The control aspects are top-notch, it could email quarantine details, block, and allow domains
Pros and Cons
- "Quarantine email alerts to users to allow the email to their inbox (tricky but handy) - tricky if one doesn't have third-party email security, handy if one has got good third party email security)."
- "Overall excellent product with great features, consider small and medium businesses to have at least basic ATP and DLP features."
- "Data protection and email security are almost the same for all the organizations, irrespective of their segment (SMB or enterprises), with standard subscription at least basic Data loss prevention and Advance threat protection can be enabled for SMB segments, it is available in enterprise version / Premium versions."
What is our primary use case?
Email, Instant Messaging with Teams, Teams Video Conference & Mobile Outlook Application.
Office 365 works very well with Microsoft Windows ECO system without any friction. Microsoft Teams video conference is a very good tool to have instant or scheduled video conferences, the quality of the video and audio is excellent but requires good internet bandwidth. As an email Admin, control aspects are top-notch, it could email quarantine details, block, allow domains, etc. especially Microsoft email filters (Spam, Malware, etc) with a basic standard subscription are on par with leaders in Email filters (Like Symantec, Barracuda, Cisco). These features are really handy for small and medium organizations. Outlook configuration for receiving and sending emails is very simple.
How has it helped my organization?
We have been struggling with quarantine email details, with office 365 as an admin, with an easy interface, we could able to trace which are all the emails are in quarantine, sometimes Genuine emails also will get blocked and quarantine, with trace option we can easily find the quarantined email and can allow the same to deliver it to recipients. IP Blocklists and country-wise, language-wise blocklist or allow list can be enabled to have better email security controls. Additional features like audit logs, message trace (delivered or failed to send or receive) are handy for IT admin personnel. And this solution can be easily connected with the help of Microsoft connectors to third-party cloud partners like Symantec, Sophos, barracuda, or Cisco email security. Last but not least exceptional channel partner and Microsoft services, based on the subscription services will be honored (like phone/email/remote, etc.)
What is most valuable?
1. Admin Console, control on allow, block, and quarantine list - always top feature as an admin.
2. Strong sharing control options in One drive & Share points.
3. Microsoft Teams (instant message or audio or video conference with excellent quality).
4. Easy integration with Microsoft Windows environment.
5. Outlook is or was an all-time favorite email application for most of the users, IMAP or Exchange configuration for sending and receiving emails are very easy and frictionless.
6. Outlook is capable of integrating multiple calendars and it can enable add ons like Webex/go-to-meeting/teams/team viewer etc...
7. Seamless integration with third-party partners for email security aspects.
8. Quarantine email alerts to users to allow the email to their inbox (tricky but handy) - tricky if one doesn't have third-party email security, handy if one has got good third party email security).
What needs improvement?
Data protection and email security are almost the same for all the organizations, irrespective of their segment (SMB or enterprises), with standard subscription at least basic Data loss prevention and Advance threat protection can be enabled for SMB segments, it is available in enterprise version / Premium versions. For basic business subscriptions, Microsoft can think of providing PC and mobile management features to enable good security for data in different devices (It comes with additional cost). Overall Microsoft can think of providing DLP and ATP (at least some basic) options to Small and Medium organizations (Its already available for premium and enterprise customers).
For how long have I used the solution?
I have been using Office 365 for two months.
What do I think about the stability of the solution?
Microsoft product works very well with the Microsoft Windows environment. (It could be windows 10/windows 7/Office 2019,2016,2013), works well with Mac Environment with Outlook as an email application.
What do I think about the scalability of the solution?
Scalability is not at all a problem when you use Microsoft products.
How are customer service and technical support?
Excellent.
Which solution did I use previously and why did I switch?
We were using IBM Smart Cloud Notes (IBM Verse). Switch because of IBM Email solutions migrated to HCL technologies, the cost of subscriptions are very high with external data centers with disaster recovery. So thought of switch over to Microsoft (Since Microsoft is a reliable player in the globe).
How was the initial setup?
Very easy, no third party support is required. Microsoft services team will definitely help you in this with a single service request (at least the basic setup).
What about the implementation team?
We have done the deployment with an internal team.
What was our ROI?
Maximum two months with the features or products like Microsoft Teams, OneDrive, and SharePoint (these are bundled with Basic business subscription) that's a great move from Microsoft.
What's my experience with pricing, setup cost, and licensing?
Pricing and licensing are not an issue with Microsoft - they offer good prices for any subscription. Migrating from other solutions like IBM Domino (NSF format emails) is tricky because Microsoft outlook only accepts *.PST (Windows) or *.OLM (Mac Book) converted emails to have a backup of your older emails or till the last email before the switch over to Microsoft email solution.
Which other solutions did I evaluate?
We have evaluated HCL & Google Suite.
What other advice do I have?
Overall excellent product with great features, consider small and medium businesses to have at least basic ATP and DLP features.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure

Director - R&D at Axtria - Ingenious Insights
Promotes collaboration and we can access our documents from anywhere
Pros and Cons
- "Using Office 365 has allowed us to go digital and onboard people seamlessly for working at home during the COVID pandemic."
- "Integration with other platforms can be improved."
What is our primary use case?
Our primary use is for document management.
We use Sharepoint for managing documents, Teams for collaboration, Excel, Word, PowerPoint, and Outlook for email management. We also use the document creator for creating internal surveys.
How has it helped my organization?
Using Office 365 has allowed us to go digital and onboard people seamlessly for working at home during the COVID pandemic.
What is most valuable?
The most valuable feature is that we can access our documents from anywhere. If we aren't using our official laptops, we can still go online to work. I think it helps a lot.
What needs improvement?
Integration with other platforms can be improved. As it is now, it works really well with Azure and other products from Microsoft. However, if you want to integrate something outside of this, especially with Excel, it gives us challenges. There are a lot of use cases in Excel where we want to integrate with other services.
For how long have I used the solution?
I have been using Office 365 for the past couple of years.
What do I think about the stability of the solution?
I think that Office 365 is pretty stable. We are using it pretty extensively and I have not encountered any major issues.
What do I think about the scalability of the solution?
I'm pretty sure that this platform is very scalable because now, almost everybody is working from home and using it. We have between 1,500 and 1,600 users who are scattered across geography. Approximately 1,300 are in India and the remainder is spread across the US.
How are customer service and technical support?
I do not deal with technical support personally, although because we haven't had any major issues, I think that our interaction with them has been smooth.
Which solution did I use previously and why did I switch?
Prior to using Office 365, we were using the on-premises version.
How was the initial setup?
I would not say that the initial setup is complex. Rather, it is of medium difficulty, somewhere between straightforward and complex.
Once we decided to use Office 365, we were able to onboard people seamlessly. We were able to quickly start working with Team, Skype, and other products.
What about the implementation team?
Our internal IT team took charge of the implementation and deployment. They were able to complete it without assistance. The deployment is now fairly automatic for new people and there is very little time spent on maintenance.
What other advice do I have?
In summary, the features are really good, it has made our lives easy, and I highly recommend it.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Solution Manager at Softtek
Good integration between products in the suite, and I can do my work from anywhere
Pros and Cons
- "I like that it is cloud-based, wherefrom any computer I can access my documents and continue working."
- "The most valuable feature is the integration, where all of the modules are talking to each other."
- "I would like to see the macro functionality in Excel made simpler."
What is our primary use case?
I use Office 365 for a variety of things including sending emails to customers and colleagues, creating PowerPoint presentations, using Excel, and using Access.
What is most valuable?
The most valuable feature is the integration, where all of the modules are talking to each other.
I like that it is cloud-based, wherefrom any computer I can access my documents and continue working. Even if my computer is down or something has happened to it, I can use another computer for work.
What needs improvement?
I would like to see the macro functionality in Excel made simpler.
Excel should be made more intelligent in terms of being able to figure out data types. For example, it should understand that if I have 16,000 records, it should know the datatype of each of the columns. There might be numbers, dates, and other types of data, and it should be able to recognize these based on context. If this were the case then it would make things easier for me.
I would like to see Azure artificial intelligence available in Office 365 so that it is available to everyone.
For how long have I used the solution?
I have been using Office 365 for the past three years.
What do I think about the stability of the solution?
The stability is great. I have never faced any such issues. If I load too much into PowerPoint then it will slow down a little bit, but nothing like the old desktop version. When I was using the desktop version of Office, it would hang. The cloud version is far more stable.
What do I think about the scalability of the solution?
Office 365 is scalable, although collaboration has to happen through SharePoint. I would say that it can scale to large, global enterprises very easily.
How are customer service and technical support?
I have never spoken to technical support for Microsoft Office. I have never had a problem that needed it.
How was the initial setup?
The initial setup is easy because it's online. You pay for it and you get it, and that's it.
What's my experience with pricing, setup cost, and licensing?
I think that we pay $9.99 USD per user, monthly. There are yearly packages available.
What other advice do I have?
I would rate this solution a nine out of ten.

Cloud Security Lead at a security firm with 1-10 employees
Extremely reliable with an all-encompassing suite of features
Pros and Cons
- "Reliable without any glitches."
- "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."
- "Could include integration with other single sign-on solutions."
- "The product could be improved if there was integration with other single sign-on solutions that are available on the market."
What is our primary use case?
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.
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.
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 technical 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

Agile Coach at SWIFT
Collaboration and documentation improve project management, but security needs enhancement
Pros and Cons
- "Office 365 is particularly valuable for collaboration, reporting, and documentation related to compliance."
- "I rate Office 365 six out of ten. It does the job without much excitement and fits the needs of people due to a lack of alternatives."
What is our primary use case?
I mostly use Office 365 for project management and reporting. I utilize tools like Excel, Jira, Confluence, Microsoft Suites, and others primarily for collaboration, documentation, and compliance reporting.
What is most valuable?
Office 365 is particularly valuable for collaboration, reporting, and documentation related to compliance. The tools are utilized for project management as well, with Excel, Jira, Confluence, and the Microsoft Suite playing significant roles.
What needs improvement?
When buying an external product, I believe the security is lower. Therefore, there is room for improvement or development internally for better security.
For how long have I used the solution?
I have been using Office 365 for more than ten years.
What do I think about the stability of the solution?
From time to time, I face minor issues, but nothing really major has occurred.
How are customer service and support?
I mostly rely on the community for support and have not had any direct contact with Microsoft's technical support.
How would you rate customer service and support?
Neutral
How was the initial setup?
I was not involved in the deployment of the tools.
What's my experience with pricing, setup cost, and licensing?
I do not have a clear understanding of the cost, as I use the tools provided by the customer. I know they are quite expensive.
What other advice do I have?
I rate Office 365 six out of ten. It does the job without much excitement and fits the needs of people due to a lack of alternatives. However, it is known to be quite expensive.
Which deployment model are you using for this solution?

Office 365 Enterprise
Pros and Cons
- "Office 365 plus the 64-bit 2016 versions of the Office desktop applications is a great combination that I could not function without."
- "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."
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.
