Learn what your peers think about Office 365. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
896,467 professionals have used our research since 2012.
What was my experience with deployment of the solution?
The initial setup process for Office 365 is not complex; it is straightforward.
What do I think about the stability of the solution?
For stability, I would rate Office 365 a nine out of ten.
What do I think about the scalability of the solution?
I would rate Office 365 a ten for scalability, ability to scale, and ability to expand.
How are customer service and support?
I would rate Microsoft technical support a five or six, as the support is not satisfactory.
The first level of support is not very helpful, especially when the issue is critical and they need to engage the backend team or the level three support team to fix the issue, causing escalations that take time to resolve the issue in a timely manner.
Which solution did I use previously and why did I switch?
Office 365 is more preferable to me than GCP.
The reason is that functionality-wise, Office 365 is easier to use, and the functionality, scalability, and feature set that are available in Microsoft are much easier to use and understand.
How was the initial setup?
The initial setup process for Office 365 is not complex; it is straightforward.
What about the implementation team?
I am working with both the hybrid model implementation and the cloud-only model for Office 365.
What was our ROI?
I would obviously recommend it to other users.
What's my experience with pricing, setup cost, and licensing?
For pricing, I would rate Office 365 a three, where one is high.
Which other solutions did I evaluate?
I can compare Office 365 with Google GCP, as GCP mostly provides the same feature set.
What other advice do I have?
Office 365 meets all our requirements, and I don't have any additional features I would add.
It is mostly suitable for enterprise sales companies.
I recommend Office 365 for around 3,000 users, based on my experience.

Efficient data analysis and seamless integration improve productivity
Pros and Cons
- "The pivot table feature is most valuable because it helps me understand large volumes of data in a very short time."
- "The pivot table feature is most valuable because it helps me understand large volumes of data in a very short time."
- "We have experienced stability issues."
What is our primary use case?
We use Office 365, specifically Excel, Word, PowerPoint, and Google Forms. These tools are used for pivot tables, data analysis, and data maintenance. Our team of 15 members all uses Office 365 to maintain and analyze data.
What is most valuable?
The pivot table feature is most valuable because it helps me understand large volumes of data in a very short time.
The integration with AI will help explore new features of Office 365. Currently, the AI integration is not good and not user-friendly.
Time savings is another valuable feature. Cost savings depend upon the scalability of the business.
What needs improvement?
The regression modules which help with regression analysis are the most difficult to use.
For how long have I used the solution?
We have been using the solution for three to four years.
What was my experience with deployment of the solution?
We did not find any difficulties integrating Office 365.
What do I think about the stability of the solution?

Manager, Information Technology Services at a manufacturing company with 1,001-5,000 employees
Enabling seamless work on the go and easy access to files with strong productivity features
Pros and Cons
- "Especially now with Office 365, you can access your files always on the go—you do not have to use your laptop or connect to the company network, and as long as you have a device, even a mobile device, you can actually use it and access your emails."
- "Especially now with Office 365, you can access your files always on the go—you do not have to use your laptop or connect to the company network, and as long as you have a device, even a mobile device, you can actually use it and access your emails."
- "Sometimes you have to wait for a while. If they could improve their response time, it would be better."
What is our primary use case?
My use case for Office 365 is because it is most suited to our environment. Most companies in Singapore use Office 365 because it is easier to use, and most people have grown with Microsoft solutions from the start. The solution has evolved to Office 365 because it is easier to use and seamless. Especially now with Office 365, you can access your files always on the go. You do not have to use your laptop or connect to the company network. As long as you have a device, even a mobile device, you can actually use it and access your emails.
What is most valuable?
I am currently focusing on productivity and have started using Microsoft Planner. I have had issues with time management because we are dealing with end user support, meetings, projects, and ad hoc activities. Sometimes, it is difficult to track via email and using tasks. I researched online for the easiest way to manage this without paying, which led me to discover Microsoft Planner.
Teams is quite effective because it has tremendously improved in terms of video conferencing and integration. You can use it to call an outside number, making it easier to interact within your company and call mobile phones via Teams. With the implementation of online federation, you can contact or add contacts that are not within the same tenant, making communication easier.
What needs improvement?
What I would suggest Microsoft improve is creating a one-stop shop where you can see everything in a single pane of glass. For example, in Microsoft Intune, you have to access the Entra ID separately, and you have to access Microsoft Intune separately. Although these features are available on one website, if they could create a seamless integration to see everything in a single pane of glass, it would be more efficient. I believe they are working on this already or have plans to implement it.
What do I think about the stability of the solution?
I would rate the stability of Office 365 as nine. I have been working in IT for about 15 years and we have experienced crashes on the solution, especially with Outlook and the Office 365 suite. Overall, it is quite stable.
What do I think about the scalability of the solution?
I would rate the scalability of this solution as eight out of ten. Now many applications are using SaaS, and when Microsoft developed Office 365, it was a huge step for SaaS solutions, especially during COVID. If we were using on-premise solutions, it would have been difficult for users to work from home, as they would need to install desktop applications to access Outlook and other Office applications. With the integration of Office 365, when you access your files, you do not need to log into your laptop. If you are outside, you can simply access your phone, open your email, and open PowerPoint easily.
How are customer service and support?
I seldom contact Microsoft regarding technical issues, but when I have, they have been quite helpful. Sometimes you have to wait for a while. If they could improve their response time, it would be better. Normally in IT infrastructure, you can have 24/7 ticket prioritization. Perhaps to them our issue may not be P1. However, as a customer, they need to understand it is very important for us to resolve issues, especially if it involves our VIP users. I would rate their technical support as seven, based on my experience.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I used another solution before Office 365 a very long time ago. We used Lotus Notes in our previous company.
What other advice do I have?
Based on my experience, I would recommend Office 365 to other people, even to my family. During the COVID period, my sisters and their children had to do schooling at home because they could not go out. At that time, I purchased the family Office 365 so I could share with them, which made things easier. I give Office 365 a rating of 10 out of 10.

My name is Adam Stevenson, and I work for Stantec as a talent development advisor. My email is adam.stevenson@stantec.co.uk.
I am a real user of Microsoft products, not a partner, and I would prefer my opinion about Office 365 to be anonymous on the platform.
I am working with both Cornerstone and LinkedIn Learning because I'm working with HR tools and employee involving solutions, and needed research for a presentation.
I couldn't specify which cloud we are using for the deployment of Office 365.
I would rate Office 365 a 9 out of 10 for all products overall.
I am totally satisfied with the security part of Microsoft for that software.

React Native Team Lead at Visible Magic
Enable seamless integration across platforms and suggest enhanced collaboration options
Pros and Cons
- "The most valuable features of Office 365 include its ecosystem integration capabilities, allowing for seamless usage across different platforms."
What is our primary use case?
I primarily use Office 365 for handling documents and spreadsheets. In my daily work, however, I am not a frequent user of office applications as I am more of a developer. We mainly use Google for collaboration and other tools like Notion, Miro, and Figma.
What is most valuable?
The most valuable features of Office 365 include its ecosystem integration capabilities, allowing for seamless usage across different platforms. The default settings work well for more than a decade, which is a testament to its user-friendly design. I also find the autosave and backup features, such as saving to iCloud and local storage, very useful. Although I use only formulas in Excel for basic calculations, this feature also provides time-saving benefits.
What needs improvement?
I do not have any specific complaints about Office 365, such as downtime, stability issues, or technical errors. I believe the choice of office apps often depends on the existing ecosystem of the business, and since Office 365 has comprehensive coverage, I am not missing any features that the competition provides.
For how long have I used the solution?
I have worked with Microsoft Office and its suite for over twenty years
What do I think about the stability of the solution?
I have not experienced downtime, stability issues, or data loss when using Office 365. It is a reliable solution.
How are customer service and support?
I have never contacted customer support for Office 365, so I can't provide feedback on their services.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup of Office 365 was straightforward and did not present any challenges. The default settings have been satisfactory.
What other advice do I have?
I rate Office 365 seven out of ten. I emphasize the integration capabilities of Office 365, though other applications like Notion, Confluence, and various Google tools are also important in my workflow. Overall, I would rate the solution a seven out of ten.

Pros and Cons
- "The ChatGPT add-in that is accessible now for Excel is one of the most helpful features of Office 365 because it gives you the opportunity to process a lot of data in a really short time."
- "The ChatGPT add-in that is accessible now for Excel is one of the most helpful features of Office 365 because it gives you the opportunity to process a lot of data in a really short time."
- "Regarding Excel processing a lot of data, I'm currently working with an Excel sheet that has approximately 10,000 lines, and I really see it struggling to process due to the many functions it contains, leading to downtime and loading problems."
What is our primary use case?
Excel and PowerPoint are part of Office 365, which I constantly use.
I have been working with Excel and PowerPoint for the last three years or so, since my studies started, while simultaneously working as a working student or as an intern, using them permanently during my lectures.
What is most valuable?
The ChatGPT add-in that is accessible now for Excel is one of the most helpful features of Office 365 because it gives you the opportunity to process a lot of data in a really short time.
I use the ChatGPT add-in to process a lot of data quickly within Excel.
I have the ChatGPT add-in directly in Excel. I used the API in my previous position as a working student in a company that had a lot of data to be processed, and I was working with the ChatGPT add-in to process it correctly.
What needs improvement?
The user interface of PowerPoint could be improved in future updates to make it easier to find features via search, because sometimes it's difficult to locate certain applications as the buttons are too small.
Regarding Excel processing a lot of data, I'm currently working with an Excel sheet that has approximately 10,000 lines, and I really see it struggling to process due to the many functions it contains, leading to downtime and loading problems.
For how long have I used the solution?
I have been using Office 365 for the last three years.
What was my experience with deployment of the solution?
I don't have any experience with the initial setup because Office 365 applications were already pre-installed on all the devices that I was using.
What do I think about the stability of the solution?
It experiences issues only with high volume and numerous functions in the tables that we're using.
What do I think about the scalability of the solution?
It's reasonable because with the Office 365 setup, you have access to a lot of devices and applications, especially when utilizing process automation tools such as Power Automate, making it reasonable in price.
How are customer service and support?
I have never directly contacted Microsoft regarding Office 365 because I didn't really need to, as any issues were just on my side.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I was working in a former position with Hotspots where I used some automation tools to make processes more automated.
How was the initial setup?
I don't have any experience with the initial setup because Office 365 applications were already pre-installed on all the devices that I was using.
What other advice do I have?
I'm currently working with the whole Microsoft setup, which includes tools such as Windows 10, Office 365, and Zoom.
I mainly use Excel and PowerPoint within Office 365.
I did some data analysis while working in strategic procurement of a company and in data management of another company while using Excel and PowerPoint.
I'm currently not working with any advanced features such as automation in Excel or SharePoint workflows, but I was using some automation tools in a former position.
I understand that Excel has to process a lot of data and, especially when working with AI, there could be downtimes.
I would rate Office 365 eight out of ten for its functionalities and features.

Power Platform Advisor and Head of Power Platform Team at Orbis AG
Daily routines streamline with enhanced communication tools
Pros and Cons
- "What I appreciate in the Office 365 world is having Copilot as an assistant that can help automate many things."
- "What I appreciate in the Office 365 world is having Copilot as an assistant that can help automate many things."
- "Sometimes there are simple bugs. For example, I create an appointment, and it disappears or is differently showcased in Microsoft Teams because Teams also has a meeting section as opposed to Outlook, but these are just temporary bugs."
What is our primary use case?
My most common use case involves starting my day with Office 365, specifically with Outlook and Microsoft Teams. Teams is very good, and I am trying to get used to the new user interface because it changed a bit, but I spend a lot of time in Teams and, of course, also in Outlook. I also use Microsoft Loop for structuring and organizing meetings that I have with my colleagues. It's a very handy way of keeping the information without being over-structured, and I use Loop because I prefer to note something down instead of just saying 'Oh, I will remember this' and not writing it anywhere. Rather than using a very complex, huge application that needs time to open and has a very big structure, Loop is something in between, and I find it a very useful tool that I also use on a daily basis. If I would have to pick three, they would be Outlook, Microsoft Teams, and Loop.
What is most valuable?
In terms of advanced features, those are things that we usually do with Power Platform. We try to avoid building super complex Excel templates when we can use another more suitable tool or build a Power App for that.
What I appreciate in the Office 365 world is having Copilot as an assistant that can help automate many things. For example, if you need to translate something and want to ensure the translation looks professional and has a specific tone—formal, informal, friendly—then you can use Copilot for that or get a first idea and then edit the result. It helps to summarize meetings in Microsoft Teams and points out the most important key aspects discussed in the meeting.
If you have people who were not able to join the meeting, you can copy the summary and the next steps and send it to them. I find the extension with Copilot very good. One of my favorites is Copilot in Microsoft Outlook, which helps you find a meeting with people who have very busy calendars. I have a lot of appointments, and it's difficult to find a free slot. When I need help finding a slot that works for three or four colleagues with busy calendars, Copilot in Outlook helps with that.
What needs improvement?
In terms of improvements in Office 365, there might be things that need to be improved in many tools. I have some improvement suggestions for Copilot, but not the actual product itself, because I grew up with these tools. I did not know it differently. I had to use Outlook, and I learned how to do it, and now it's the default for me.
Sometimes there are simple bugs. For example, I create an appointment, and it disappears or is differently showcased in Microsoft Teams because Teams also has a meeting section as opposed to Outlook, but these are just temporary bugs. In general, these tools are very synchronized with each other.
What I would to be able to do is copy-paste meetings. If I want to send several blockers or potential meetings to the customer, I create the first one, and I want to be able to paste this first blocker on another day as blocker two, just paste and change the title. That's difficult to do. This is not something which works with Outlook yet.
For how long have I used the solution?
I have been working with Office 365 for 7 years.
Which other solutions did I evaluate?
Regarding whether I consider Office 365 a cost-effective solution, I would say that if in the normal packaging, using AI—which will become the norm and the default in the near future—costs extra in Outlook, it would be nice to have those integrated in the licensing and not have to pay extra for Copilot or extra AI features. AI should be an intuitive thing and a daily job, and perhaps Microsoft should find a way to make the model still financially beneficial for them without raising the price just because we have new features and AI capabilities.
What other advice do I have?
The name of the company is Orbis SE now. It's just the company change; the rest remains the same. On a scale of one to ten, I rate Office 365 an eight out of ten.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Reliability and seamless collaboration elevate team productivity
Pros and Cons
- "The return on investment is always an improvement, and I think it's a significant improvement due to the many integration options available."
- "The return on investment is always an improvement, and I think it's a significant improvement due to the many integration options available."
- "Currently, Microsoft can improve Office 365 by enhancing the persistence of the user experience from platform to platform and screen to screen, ensuring that wherever you log in, whatever you're doing, everything is still readily accessible and intuitive, as you left it."
What is our primary use case?
Some of the use cases I focus on include collaboration, communication, and information sharing as well as project management.
In terms of industries, I focus on health care and manufacturing.
What is most valuable?
Some of the most valuable features I found with Office 365 include Teams integration with various applications, allowing for the addition of various Teams apps into Teams channels for managing teams and collaboration.
The SharePoint integration has proven beneficial.
SharePoint impacts my project management by providing shared collaborative information where people can refer back to it without having to move the information around; you can just send links instead of needing to download documents all the time.
What needs improvement?
Currently, Microsoft can improve Office 365 by enhancing the persistence of the user experience from platform to platform and screen to screen, ensuring that wherever you log in, whatever you're doing, everything is still readily accessible and intuitive, as you left it.
For how long have I used the solution?
I've had experience with Office 365 since it's been released, since its existence.
What do I think about the stability of the solution?
I rate Office 365 as reliable and stable. I haven't had any significant outages or application errors or failures, so once you put it in service in your enterprise, there's not a whole lot of product issues, mostly user issues.
How are customer service and support?
I really don't go to technical support very often, as we usually handle our own in-house support, but when I've escalated to Microsoft on occasion, they've been very responsive, so I would say they're adequate.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I am familiar with other types of collaboration tools, such as Google platforms, although I haven't used them in a while, so it's come a long way since my last experience.
The main difference between Office 365 and perhaps Google is that Microsoft products are much better integrated across all those platform products.
How was the initial setup?
Setting it up is fairly well thought out for the end-user experience at the moment, especially for the initial engagement. They've developed a lot of on-demand help and training resources for new and casual users, so I believe they've done a good job with it.
What was our ROI?
The return on investment is always an improvement. If they don't have it, it's a huge improvement going from no collaboration to a collaborative platform, and I think it's a significant improvement due to the many integration options available.
What's my experience with pricing, setup cost, and licensing?
As for the pricing for Microsoft Office 365, it can always be cheaper.
The cost is probably at least in the upper two-thirds range.
What other advice do I have?
I would recommend Office 365 to others.
Office 365 utilizes AI, and while it's just getting started, I think the integration is still in its beginning stages; there's likely to be a whole lot more integration across all the application stack within the next year or so.
Using AI has proven to be a good resource for creating a first draft when we start getting stuff started.
On a scale of 1-10, I rate Office 365 a 10.
