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.

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

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.

Solution Architect & Cloud Architect & Project Manager at a tech company with 51-200 employees
If you have a global solution, you can go from one product to the other very easily
Pros and Cons
- "If you have a global solution, you can go from one product to the other very easily. And then you can share data between all the different tools of Office which is good because participation and sharing is very good. That's the most important aspect of Office 365."
- "A need that a company like ours has is that we want to be able to have data flow into one tool, for example, for all the management of tasks through the company and workflow of who is doing what and so on. There are no real solutions for this at the moment in Office 365. It would be nice if they could implement this in the next release, so we can have one solution from one company giving us the whole data and flow of data into the company."

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
