My use case is mainly the email solution of Office 365. I use the exchange online for my emails, corporate emails. I use OneDrive for saving my data on the internet, and the other good features are Excel, Word and PowerPoint online, which allows me to create online documents. I also sometimes use Microsoft Teams within Office 365. We generally use Teams for our video conference meetings and presentation meetings. We also sometimes use SharePoint to share documents with people outside our organization. I am a cloud security lead and we are users of Office 365.

Extremely reliable with an all-encompassing suite of features
Pros and Cons
- "Reliable without any glitches."
- "Could include integration with other single sign-on solutions."
What is our primary use case?
What is most valuable?
What I like most about Office 365 is its reliability and that I haven't experienced any outages, it's always worked fine for me. It also has a unique 'giving' feature in that if I go for Office 365 licensing for a particular license level, Microsoft also offers me other services along with Office 365.
What needs improvement?
The product could be improved if there was integration with other single sign-on solutions that are available on the market. I'd also like to see integration with other privileged identity or access management solutions. If there are only particular solutions that we have to go with and other market leaders have other solutions that we'd like, then that becomes costly. If they came up with more access or solution integrations that were less expensive, then that would be helpful.
Microsoft should come up with some documentation or presentation related to specific use cases. There are times when companies or organizations migrate to Office 365, but they are not aware of each and every feature that's available and that they could be using. I think they should have special feature-based training sessions, where information can be shared with users. It can be subdivided into departments whether it's accounting, HR, technical.
For how long have I used the solution?
I've been using this solution for more than five years.

861,524 professionals have used our research since 2012.
What do I think about the stability of the solution?
I think this is a very stable solution.
What do I think about the scalability of the solution?
This is a scalable solution. You just need to invest in the new added user licenses and get those onboard. It is on your tenant ID, which is already created. So I guess scalability is quite easy in Office 365. You can go in for new licenses every year and easily scale up. My organization currently has between 400-500 users of this product. We have a team of two or three who deal with it. We plan to increase usage and we already give training sessions on usage of this product on a use case basis depending on the department you're working in.
How are customer service and support?
The technical support is quite good from Microsoft.
Which solution did I use previously and why did I switch?
We were using G-Suite before this but G-Suite doesn't have the features that Office 365 offers. We have access to Teams, video conferencing, SharePoint and all the other features which is why we thought it was a better solution for us.
How was the initial setup?
The initial setup was straightforward. I think deployment took around one and a half months. and the strategy was to get a batch of users first migrated to Office 365 and then continue in batches until everyone was on board. We worked directly with Microsoft for the deployment.
What other advice do I have?
I would rate this solution a nine out of 10.
Which deployment model are you using for this solution?
Public Cloud

Head of Solutions Delivery (Systems) at a wellness & fitness company with 51-200 employees
A great all-in-one solution that's stable and has a straightforward setup
Pros and Cons
- "It's nice that it's an all-in-one solution and everything is all in one place."
- "The one big problem with the solution is if you are presenting in Teams and someone puts their hand up, you don't get a notification. If you are running a meeting and just presenting you don't know that people have their hands up and want to ask a question."
What is our primary use case?
We use it primarily for collaboration across teams. We use it to collaborate either via email or we use Teams quite a lot. For all of our meetings, we are now using Teams. Then we use the planner boards and things in Teams as well for keeping track of the work that we need to do.
What is most valuable?
It's nice that it's an all-in-one solution and everything is all in one place.
You can have your meetings, your meeting history, you can record meetings, you've got a place for meeting notes, you can create your task board, or have planner boards, or you can use other tools like Trello within Teams.
Just the integration that it gives allows us a lot of different other platforms in basically one place, and it's good to have everything at our fingertips if and when we need it.
What needs improvement?
The one big problem with the solution is if you are presenting in Teams and someone puts their hand up, you don't get a notification. If you are running a meeting and just presenting you don't know that people have their hands up and want to ask a question.
What I don't like is that not all of the capabilities exist on a chat. You have to have a Teams channel to use, for example, a planner. It would be nice if I could still use a planner board on a chat.
For how long have I used the solution?
We've been using the solution for more than a year.
What do I think about the stability of the solution?
The stability of the solution is very good. We use it extensively and have run big meetings with lots of people. It has never crashed or froze on us. There aren't bugs or glitches. We've been quite satisfied with it.
What do I think about the scalability of the solution?
In terms of scalability, we haven't had any issues. We've been using it quite heavily over the last couple of months with lots and lots of people running different meetings at the same time, and lots of people in a single meeting. We haven't had any issues so far in terms of scaling the solution in that sense.
We've got probably about 5,000 people in our organization using it and they vary from technical IT teams to our business unit is across different areas, like marketing, finance, HR, etc. Pretty much the whole organization is using it. I don't think we could possibly increase usage at this point as it's already so pervasive in our organization. That said, we have no plans to move away from it.
How are customer service and technical support?
If we do have issues, we engage it with our internal support and they would then reach out to the third party support. Therefore, I don't know what that support looks like.
Which solution did I use previously and why did I switch?
We still use Office, or Outlook, for emails. Previously we used that and then we used Slack for collaboration instead of Teams.
Teams obviously has more integration with other tools. Slack had the chat capability and it allowed us to have meetings, however, it didn't record meetings and it didn't have a meeting history section. You weren't able to see everyone in the meeting. Again, you didn't have the planner boards and all the other widgets that you can integrate with from a Team's point of view. Teams is more usable and has a lot more features. It's just one place where everything's captured. When we'd use Slack and we'd use Trello, they were separate tools, and information was in two different places. Teams basically gives you Slack and Trello together, along with so many other things.
How was the initial setup?
The initial setup is not complex at all. It is very straightforward, in my opinion.
Our central team rolled it out, therefore I wasn't part of the deployment process. I'm not sure how long it took to roll everything out.
I'm not sure how many people are needed to maintain the solution.
What about the implementation team?
I do know our central team rolled it out, however, I'm not sure if we brought on any outside help.
What's my experience with pricing, setup cost, and licensing?
I'm not sure how much our organization pays for licensing.
What other advice do I have?
We're just a customer. We do not have a partnership with Microsoft.
I'm not sure which version of the solution we are currently using.
I'd recommend this solution to other organizations.
I'd rate the solution eight out of ten.
Which deployment model are you using for this solution?
On-premises

IT Officer at a manufacturing company with 201-500 employees
A good, complete and secure suite of products for standard business tasks
Pros and Cons
- "The products are quite simple for the end-users to use, the up-time is very good, the product is practically maintenance-free, and the multi-layer security is excellent from the security standpoint."
- "The online applications have limited functionality compared to the local applications."
What is our primary use case?
Our primary use for the product is for performing office tasks like word processing for critical business staff. I work with the product mostly from the administrative side but also have experience using the product itself.
How has it helped my organization?
Email transmission has greatly improved since we migrated to office 365 , collaboration with SharePoint and Teams has increased users productivity, downtime is minimal and I.T management is very minimal hence we can concentrate on other I.T tasks.
What is most valuable?
The thing I have found most valuable is that the product is quite simple for end-user so there is not much reason to use the product support. The support for users is good and adapting the product from the user's perspective is quite easy.
The uptime of the solution is quite good, I can say it has about 98 to 99% uptime.
The product is also easy from the standpoint of administration, especially for the IT team. We have good control over who has access to the program components and what parts they can use. In terms of the IT team, it makes our work quite easy. We do not need to spend too much time monitoring the solution because it is quite good.
Security-wise, it is also good. There is multi-layer authentication which I think is good from a security standpoint.
And finally, the reporting is also good.
What needs improvement?
One part of the suite that can be improved is their online applications. Those are quite limited compared to the desktop applications and this can make them more difficult to use. That is one area of improvement that Microsoft should address.
The cost is a big challenge. It is really quite expensive and puts quite a strain on our budget. Because of that, we have to set a limitation on the use of the online application and the distribution of user licenses. If the pricing were more friendly, we might want to get more people using the product.
The pricing is really the key feature that holds us back from making more and better use of the product.
For how long have I used the solution?
I have been using the product for about one year.
What do I think about the stability of the solution?
The product is very stable. We only have very rare issues when something goes wrong.
What do I think about the scalability of the solution?
The scalability of Office 365 is quite good. The cost of the licenses is the main issue when it comes to scalability, not the product itself. We have to try to balance the number of licenses according to the most critical users.
We do plan to increase usage over time since the company will always grow. As the number of critical users increases, we will need to purchase more licenses.
So there is the possibility of changing the number of licenses we are using and that would be all we need to do to scale usage with some very minor attention to security issues.
How are customer service and technical support?
The technical support is good. Probably the best thing about tech support is that we do not need to be involved with them because the product is stable.
Which solution did I use previously and why did I switch?
We previously used on-premise Exchange server , the solution was good but administration of the solution was very time consuming , security was a key concern and downtime was very frequent.
How was the initial setup?
The initial setup was okay. It was not too complex, but it also was not as straightforward as it might have been.
What about the implementation team?
We implemented through a Microsoft vendor and their expertise is very good.
What's my experience with pricing, setup cost, and licensing?
We find that the licensing costs are high enough that it makes us restrict the number of users in our organization.
Which other solutions did I evaluate?
We evaluated G-Suite
What other advice do I have?
The advice I would give to others who are looking into implementing Office 365 is that this solution is a good one for anybody needing a scalable, stable solution with good uptime.
It is virtually a worry-free solution especially from the standpoint of IT administrators.
On the scale from one to ten, with one being the worst and ten being the best, I would rate this product as a nine-out-of-ten. I would rate OneDrive as a nine as well.
Which deployment model are you using for this solution?
Hybrid Cloud

BI/Qlikview Architect at DataForce Ltd.
Great for building formulas, good integration with other apps, and very stable
Pros and Cons
- "The integration with other applications is pretty good."
- "If two people update the same file, it causes issues."
What is our primary use case?
We primarily use the solution for Excel, for analyzing data, and PowerPoint, for presentations.
What is most valuable?
There aren't any features that jump out at me as being valuable.
The Excel application's ability to handle spreadsheets and calculations if very useful.
The integration with other applications is pretty good.
What needs improvement?
There's a matter of sharing with other users. If someone is working on it or disconnects from the mutual storage, I need to save it as is and I need to override it. I cannot work together with other users on the same document. That may be possible on the cloud version of Office 365, however, I'm not sure as we use the desktop version. This is one issue we have with the solution.
If two people update the same file, it causes issues.
For how long have I used the solution?
I've only been at this company for three months, and two months in the office. I've been using Office 365 since I arrived.
What do I think about the stability of the solution?
The solution is quite stable. I haven't had any issues so fr. There are no bugs or glitches. It doesn't freeze or crash. It's very reliable.
What do I think about the scalability of the solution?
I'm not sure if scalability is an issue for this kind of application.
In our organization, there are hundreds or maybe even thousands of users. Everybody probably has some instance of it, whether it's on the cloud or on-prem. it's pretty prevalent across departments.
We are a huge company. For all of the applications we use, we have 20-30 people engaging in the support of all the projects, and not this solution in particular.
My understanding is the organization is planning to move exclusively to Office 365 and probably to the cloud. That's the next step we are taking.
How are customer service and technical support?
I have never personally dealt with technical support, however, I believe it to be quite good.
Which solution did I use previously and why did I switch?
I don't believe the organization used a different product before this solution was implemented.
How was the initial setup?
The initial setup was straightforward. It wasn't complex at all. However, I'm used to working in the Microsoft environment.
I'm not sure how long deployment actually takes.
What about the implementation team?
I don't know if we used an integrator or reseller to assist in the installation of the product, as I only really started at the company a few months ago.
What's my experience with pricing, setup cost, and licensing?
I don't deal with accounting, so I'm unsure as to what the licensing costs would be.
What other advice do I have?
We're a Microsoft customer. We don't have a business relationship with them.
I believe I'm using the 2019 version of the solution.
While this version is on-premise, it's my understanding that the organization is testing the cloud version for future deployment.
I would certainly recommend this product to others.
I'd rate the solution nine out of ten.
Which deployment model are you using for this solution?
On-premises

Works
Multi-user editing and integration with OneDrive brings better focus and efficiency
Pros and Cons
- "The most valuable feature is the integration with OneDrive, which has allowed us, a small business, easy access to a cloud environment, with no need to back up the data from five different computers."
- "Integration between Outlook calendar and Google Calendar would be a good improvement since many of our team use Android phones and personal Gmail accounts as their main calendar application."
What is our primary use case?
Our team is comprised of five people in a small consultant firm. Office 365 allows for all team members to work on the same files at the same time on OneDrive while using the market standards (Excel, Word, PowerPoint) for file editing and creation.
We've experimented with free options, but there is no point of trying to work in a file format that is different from that of our clients. That's the main reason that led us to Office 365.
All of our workstations are Windows 10 and Office runs perfectly.
How has it helped my organization?
Easy sharing of files between team members in different locations, using both OneDrive and Office 365 (desktop and online), has improved efficiency by two times. Before using this solution, we had to rely on email to send files back and forth. No more renaming a document V1, V2, V10, Vn. Just open, edit, and let the seamless integration of Office and OneDrive deal with versions and edits.
What is most valuable?
The most valuable feature is the integration with OneDrive, which has allowed us, a small business, easy access to a cloud environment, with no need to back up the data from five different computers.
The multiple-user editing capability is helpful, improving the productivity of our team on creating and editing files together, even when in different physical locations.
File formats that are the market standard (docx, xlsx, pptx), is an important and relevant need to deal with clients' provided files.
What needs improvement?
In general, the desktop apps could be a little leaner and open faster in less powerful machines.
The interface for Outlook could use a refresh, to make it more like the other software in the suite.
Integration between Outlook calendar and Google Calendar would be a good improvement since many of our team use Android phones and personal Gmail accounts as their main calendar application.
For how long have I used the solution?
We have been using this solution for three years.
What do I think about the stability of the solution?
Office 365 is very stable. Actually, it is more stable than other similar solutions we have tried in the past (Libre Office).
How are customer service and technical support?
MS has excellent support and tech support. They really engage in solving the issues you might have with the software.
Which solution did I use previously and why did I switch?
We tried Google Docs, but it messed the formatting on our complex - designed - documents. We have also tried Libre Office, but with similar results. Only by using Office 365 were we able to read and create documents without any formatting issues.
How was the initial setup?
The initial setup was easy and our team handled it by themselves. MS support gave some advice when needed.
What about the implementation team?
We handled the implementation in-house.
Which other solutions did I evaluate?
We did not evaluate options beyond Google Docs and Libre Office. Once we understood that there was no point on going against the market standard for file formats, we went straight to Office 365.
What other advice do I have?
If you need, reach out to MS support. They were really helpful in setting things up for our team.

Document sharing and cloud access simplify remote work
What is our primary use case?
I use Office 365 for general word processing, data processing, and using its cloud storage.
How has it helped my organization?
Sharing documents has been easier, especially with remote work.
What is most valuable?
Office 365's most valuable features include its cloud storage and the ability to have the same document accessible on multiple devices. Sharing documents has been easier, especially with remote work.
What needs improvement?
It's sometimes challenging to find a file within a team as it's not always intuitive where it might be stored.
For how long have I used the solution?
I have used Office 365 for approximately ten years.
What do I think about the stability of the solution?
It is stable for the most part.
What do I think about the scalability of the solution?
I would rate its scalability as a five, indicating it does what it is designed to do, but there isn’t much room for expansion.
How was the initial setup?
On a scale of one to ten, I would say it is an eight, indicating fairly simple initial setup.
What was our ROI?
There is not a significant return on investment for personal use. However, it might provide some efficiency with time for team use.
What's my experience with pricing, setup cost, and licensing?
I am not aware of the cost at work, but the cost for personal use has increased significantly and feels expensive.
What other advice do I have?
I would recommend Office 365 to others because many people use it, making it easy for users to adapt. Overall, I would rate the solution as a nine.

Flag as inappropriate Office 365 Enterprise
Office 365 is one of my most used applications. I love the way that I can leverage the Cloud capabilities of my Office applications to access from anywhere. I have access from my phone, tablet, laptop, desktop, etc., and it is always easy. Outlook is nice when I do not have access to a laptop or phone (rare), and One Drive is my file collaboration solution. Although I like the functionality of One Drive, it can be frustrating if your IT team goes overboard on security. :) The single-sign-on we utilize at work keeps me signed in to all apps, and the applications load quickly and efficiently. Office 365 plus the 64-bit 2016 versions of the Office desktop applications is a great combination that I could not function without. I use Outlook, One Drive, Excel, Word, PowerPoint, Yammer, and Skype for Business every day, so without them, I would be "dead in the water.
What do you like best?
I like how collaborative Office 365 allows me to be on my projects. Currently, a co-author and I are working in real-time on a project. I could see her typing and commentary while I was making corrections to the APA at the bottom of the page. We can also work asynchronously on projects, store them, and return to them. The ability to work in a browser ensures that I can review, make slight edits to the document, print, and then save. As a person who is moving from a campus computer to my computer, to my printer at home, to my office printer at work, this is about as fast as having a flash chip with me at all times, but I never forget it. It also integrates well with Citation software, similar to Word 10. We have a lot of files we share, and I like how easy it is to access from any location I'm at, as long as I'm logged into my university account.
What do you dislike?
One of the things I struggle with regarding Office 365 is what is the real difference between Office 365 and Google Docs/Sheets other than the price and privacy. At my university, Office 365 is free as long as you are a student or a researcher. As soon as I leave the school though, I'll lose access to Office 365, most of the work I've saved on the system. And while it's... nice? to have so much technology (meaning Access and the other programs that come in the suite) I never use Access but I "have to" have it. I wish it integrated better with my Google Calendar so I could have an app on my phone but if that feature is available I don't have it.
Recommendations to others considering the product
If you are going to be a full-time single user of Office 365, this might make sense if it automatically updates to the latest Word, Excel, PowerPoint, or Publisher. It would make sense to pay a yearly/monthly fee to continuously have Word rather than having to buy the expensive office suite every few years or so. But, if you don't need to update to the latest software, if you aren't someone who needs Word, Excel, PowerPoint, or Publisher to be at their most flexible, and if you get around on Google just fine, I don't know if it makes sense to buy it as a single user. However, for large universities or companies that need flexibility, and collaboration for their employees, then Office 365 might be right for you.
What business problems are you solving with the product? What benefits have you realized?
I work on a lot of collaborative research projects and Office 365 lets me share files and reading and work with others. However, I really don't like their "calendar" system integration with Outlook, but I've never liked the Outlook calendar. I always use my Google calendar and I wish there was a way to sync those two, but as far as I know there isn't.
