Office 365

Learn what your peers think about Office 365. Get advice and tips from experienced pros sharing their opinions. Updated: August 2025.
865,384 professionals have used our research since 2012.
What do I think about the stability of the solution?
To be honest, in the past I used G Suite and other email providers that, use an IMAP or POP3 protocol. However, my customers were always complaining about poor email deliverability. They may occasionally send spam emails, but with Office 365, I don't have to deal with such issues. As a result, they're very good at what they do. As I previously stated, I strongly recommend it.
What do I think about the scalability of the solution?
Office 365 is scalable, but it is dependent on the situation. We don't have a problem with it from an organizational standpoint. They started with 100 employees and then added another 500 after six months, for a total of 600 employees. The setup of new users, new emails, and new applications to be assigned to the new users is straightforward.
They also provide the PowerShell command, which they provided more, development type, like, for example, you can create users, not manually, but through a script that can create users, for example, 100 users in two, three minutes, and you don't do it manually. They're fantastic.
My portfolio contains approximately 50 companies. Office 365 is our primary platform for the 50 companies. I only have one on G Suite, and the majority of them will be migrating from G Suite to 365 in the coming month.
How are customer service and support?
On a scale of one to ten, I would rate their performance a nine. However, you may encounter users who are just getting started and require a little more time to resolve the issue. But their assistance is quite efficient and simple.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
One of my teachers from the university suggested I do the course to have an official engineer certificate in Office 365. I went to the university, and I did the course, which was a one-month course. Once I learned Office 365, I was able to provide more security and more stability not only, for the company, but as well, when I was going to the interview, I was providing tables and show them that I know and I'm an official engineer for this solution. Through the courses and learning that I received at the university for Office 365 on the technical side, I discovered that there are many things that you can do with the platform. For the first time, I like them. I told myself, "I have to stop using other email platforms and start using Office 365." This is one of the reasons I participated in the movement.
How was the initial setup?
The initial setup is straightforward. You simply purchase a domain and assign it to the platform. If your domain is registered with one of the hosting platforms, such as GoDaddy, they have integration with GoDaddy, you can use it at the same time. With your GoDaddy login information, the process is going very smoothly. I didn't notice any difficulties with the setup.
What's my experience with pricing, setup cost, and licensing?
In general, we buy licenses depending on the needs of the client. Most of the time, we purchase Microsoft Exchange licenses, which are less expensive and provide only an email platform and 50 gigabytes of email storage for free.
You can begin for as little as 5 Euros per month. You will receive a discount if you choose a yearly plan. Then, depending on what license you require, it is paid 10 Euro, 12, 16, or 20 Euro, depending on how much you require. However, if you choose a yearly plan, you will receive a discount.
In terms of pricing, I would rate them a three out of five. They are not expensive, but they are not cheap. When comparing the solution to G Suite, one of their main competitors, they are priced the same. If it is also other competitors, they are very inexpensive. I can tell you that charging 5 Euros per month for an email is a small amount.
What other advice do I have?
I strongly recommend this solution. they are very good at what they do.
I work as a reseller. I am unable to be a partner. It's similar to having one in each country. For example, we charge most of the sales and pay something to Microsoft. Then, in cycles. As an authorized seller, I'm here to help.
The advice I would give them is to go with the best plan, which is both expensive and not cheap. Then they can start using it a little bit to see how the platform works, and then they can go to the Microsoft site and see how scalable the email as a mail platform is.
I would rate Office 365 a five 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?
Amazon Web Services (AWS)

Robust collaboration features improve document sharing and enhance productivity but integrating live collaboration could enhance efficiency
What is our primary use case?
I use Office 365 to make PowerPoint presentations, Microsoft Word to put together memos, and Excel for building financial models.
What is most valuable?
The most valuable features with Office 365 are Excel's robustness around financial modeling, which is super helpful for my job.
Office 365 brings a very strong return on investment through time savings and different efficiencies. We would never cut it as it is table stakes - it is necessary to operate in our world. The biggest KPI is functionality, specifically the ability to execute the work that needs to be done.
What needs improvement?
Office 365 could be improved in areas such as their collaboration functionality. I have used it before, but being able to work on documents in a cloud-connected manner with co-workers simultaneously would be super helpful. This feature is not available in the version we have.
For how long have I used the solution?
I have approximately 15 years of experience with Office 365.
Which solution did I use previously and why did I switch?
We haven't used a different collaboration tool before this; we've always had Microsoft. We currently have both Microsoft and Google Suite.
Some main differences between Microsoft and Google Suite are that Google is cloud native, enabling collaboration with people working on documents simultaneously. Google Sheets, compared to Excel, is not as robust. You sacrifice some robustness for sharing functionality. The same applies to PowerPoint versus Google Slides, where PowerPoint is much more powerful. The ability to work with others in a cloud native product is the selling point for Google Suite and represents a real benefit.
What other advice do I have?
I would recommend Office 365 to other businesses due to its robustness and functionality.
We haven't been using AI in Office 365 for document management or data analysis because we don't have Copilot, which is their AI feature. It hasn't been integrated into our work.

Transitions to advanced email increases productivity by offering more space for communication and document management
What is our primary use case?
I use Office 365 for communication, specifically for sending emails. I also use SharePoint for official documents, internal communication, and a combination of private and public SharePoint for Teams use. Additionally, I use OneDrive.
What is most valuable?
I primarily use Office 365 for email and SharePoint. The email capabilities are very handy to use, with no hidden options, allowing me to use them efficiently at any moment. Since transitioning from a simple, normal Outlook to Office 365, there has been an increase in productivity due to the larger amount of space available to handle emails without needing to delete older ones.
What needs improvement?
From my side, I don't see any improvement needed in Office 365. However, there should be more integration of Copilot.

Additionally, we use Teams and the email solutions provided within the Office 365 environment. The tool enhances productivity if the team is collaborative, helping us speed up work.

The cost of Office 365 has become a bit costlier in the last few years. We manage expenses based on user requirements, but cost optimization should be considered.

Collaboration tools have streamlined our teamwork with real-time and asynchronous editing
What is our primary use case?
I work with Excel, PowerPoint, and Word primarily. My work involves collaboration with multiple people, especially when using these tools.
What is most valuable?
The most valuable features of Office 365 for me involve collaboration. My work requires collaboration with multiple people on Excel, PowerPoint, and Word. We use real-time collaboration as well as asynchronous work, where I can continue from where someone else left off. Additionally, automation features like formulas and linkages in Excel save me substantial time, at least forty to fifty percent in certain tasks.

It helps us work with other companies securely
Pros and Cons
- "OneNote is the feature I use the most. We also frequently use the Power Apps features."
- "Office 365 could allow for smoother collaboration with other companies, which is the main reason we use it. The B2B connection is something we need, like global adverse lists between two tenants or multiple users. That's what we're missing at the moment."
What is our primary use case?
We use Office 365 for project management. Around 2,500 people at my company use it.
How has it helped my organization?
Office 365 helps us work securely with other companies.
What is most valuable?
OneNote is the feature I use the most. We also frequently use the Power Apps features.
What needs improvement?
Office 365 could allow for smoother collaboration with other companies, which is the main reason we use it. The B2B connection is something we need, like global adverse lists between two tenants or multiple users. That's what we're missing at the moment.
For how long have I used the solution?
I have been using Office 365 since I started work at this company in September last year.
What do I think about the stability of the solution?
Office 365 is highly reliable. The company hasn't had any issues so far.
How are customer service and support?
Microsoft support is great.
Which solution did I use previously and why did I switch?
The company used Nextcloud and WeTransfer in the past, but we switched because Office 365 is an all-in-one solution. However, I think Nextcloud is more usable than Office 365, but it ultimately came down to security.
How was the initial setup?
I wasn't involved with implementing Office 365, but it should be complex when you do it right because 365 is constantly evolving. You have to look at your tenant: Are things new? Are they open? Is it a security risk? What has Microsoft opened? Do I want to let all colleagues access the new features?
What's my experience with pricing, setup cost, and licensing?
We have an E3 license, and we pay 15 euros a person. 3,000 euros is a lot per month.
What other advice do I have?
I rate Office 365 eight out of 10.
Which deployment model are you using for this solution?
Hybrid Cloud
