I use it for everything that has to do with data input and of course Excel, Office and the like. It is pretty much the cornerstone software for what I do.

What do I think about the scalability of the solution?
The scalability is pretty good. But the enemy of something good, is something even better. There is always room for improvement.
Which solution did I use previously and why did I switch?
I was previously using Google Docs. I changed to Office 365 because it's more stable and I'm more familiar with it.
How was the initial setup?
The last time I set it up, it was pretty straightforward. This time, to be honest, I had an external company set it up.
What about the implementation team?
I used an external company for the installation.
What other advice do I have?
It has more features than somebody would expect, and it is worth taking a deeper look into the features available.
I would rate this solution as a seven out of ten. It does what it says that it does. However, as I said, it could be more user-friendly for inexperienced people, and of course, things can always get better.

What is most valuable?
I like Office 365's usability.
What needs improvement?
As a private user, I do not appreciate the cloud features, but I doubt that this is something Microsoft would consider a feature request.

I'd rate the solution a nine out of ten. It's great. It's a really excellent solution.
Which deployment model are you using for this solution?
On-premises

Adaptable and easy to use, with a good interface
Pros and Cons
- "Adaptable solution with a good interface. It's easy to set up and easy to use."
- "Microsoft Defender for Office 365 could use some customization, but this area for improvement is trivial."
What is our primary use case?
Microsoft Defender for Office 365 is mostly used for AI, SharePoint online, and importing information.
What is most valuable?
Microsoft Defender for Office 365 has been used here in Brazil for a long time, so the familiarity is there. It's being used by both individual and enterprise users, and it has a good interface. It's very adaptable and it's easy to market in Brazil. We've installed this solution for a lot of enterprise clients. It's a solution that's easy to use.
What needs improvement?
Microsoft Defender for Office 365 could use some customization, but it's trivial.
What do I think about the scalability of the solution?
There are some solutions that are easier to scale compared to Microsoft Defender for Office 365, but in general, its scalability is okay.
How was the initial setup?
The initial setup for this solution is very easy.
What other advice do I have?
I've been selling all kinds of solutions, including Office 365, Power BI, and Microsoft Defender for Office 365. I'm based in Brazil and I've been working with Microsoft partners. We have a whole list of customers who use Microsoft solutions. We usually deal with the newest versions and models of Microsoft products.
I don't know exactly what could be improved in this solution. There could be a small room for improvement, but I don't know what it is, or if Microsoft Defender for Office 365 really needs improvement, because it is a very solid solution.
For deployment and maintenance of this solution, we have five people who are in charge.
I don't have direct interaction with technical support, so I can't say from my experience if it's good or not, but what I observed it they give very good support.
My advice for people planning to use Microsoft Defender for Office 365 is that it's a very good solution, and they won't have problems using it.
I'm rating Microsoft Defender for Office 365 a nine out of ten.

Deputy Manager IT at Carl Bechem Lubricants India Pvt. Ltd.
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)."
- "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?
Microsoft Azure

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."
- "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."
- "Could include integration with other single sign-on solutions."
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
