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 most valuable?
OneNote is the feature I use the most. We also frequently use the Power Apps features.
What needs improvement?

857,162 professionals have used our research since 2012.
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
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Director, Customer Success at SAP
Highly stable, beneficial bundled package, and straightforward implementation
Pros and Cons
- "The most valuable feature of Office 365 is that it has many solutions bundled together."
- "Sometimes the configurations of the error troubleshooting are pretty problematic and there are a lot of issues that happen even if you follow the step-by-step guides. They can work on fixing this issue. If there are a lot of issues in your Windows or your Office or anything, you restart your PC and it works. They need to get rid of this need."
What is our primary use case?
I am using Office 365 for emails, presentations, spreadsheets, documents, PDF conversions, creation of PDFs, whiteboarding on the conference calls, OneNote for taking notes, and OneDrive for data storage.
What is most valuable?
The most valuable feature of Office 365 is that it has many solutions bundled together.
What needs improvement?
Sometimes the configurations of the error troubleshooting are pretty problematic and there are a lot of issues that happen even if you follow the step-by-step guides. They can work on fixing this issue. If there are a lot of issues in your Windows or your Office or anything, you restart your PC and it works. They need to get rid of this need.
While using Microsoft OneDrive, which is part of Office 365, we use it to store all our data files. At this point in time, OneDrive doesn't support PST files. PST files are for our Outlook data. OneDrive doesn't take backup of the PST files, which is a big setback.
In the future release, there should be better automation. When you're scheduling a meeting, it should be in an automated way, it should prove us with more information about kind room slots. If there is a travel booking that is coming onto your email, it should go ahead and block your calendar as well in accordance with the times. This is an Outlook-related suggestion.
On PowerPoint, there could be more templates that could be added in, which makes your job slightly easier when you're designing something.
Excel, I think is a phenomenal solution, the only problem is it becomes very heavy as data increases. If they can work towards compression, that should be helpful.
For how long have I used the solution?
I have been using Office 365 since they launched the solution.
What do I think about the stability of the solution?
The stability of Office 365 is fantastic.
What do I think about the scalability of the solution?
Office 365 is scalable.
We have 40,000 people using the solution in my organization.
How are customer service and support?
We use our internal support for Office 365.
How was the initial setup?
Office 365 is very straightforward to implement.
What's my experience with pricing, setup cost, and licensing?
There is a license required to use this solution.
The price of Office 365 is very expensive.
What other advice do I have?
I would recommend this solution to others, it is a very good solution.
I rate Office 365 a nine out of ten because I have faced certain issues, such as the solution crashing. If there are solution issues, it's difficult to resolve and that's the reason why I'm taking that one point away. Office 365t helps me do my job, I'm very happy with the products.

Manager, Cybersecurity Engineering and Audit at a tech services company with 11-50 employees
Suite of tools for productivity and collaboration, is straightforward to set up and quick to deploy
Pros and Cons
- "The most valuable features of Office 365 are Word, PowerPoint, Excel, and Teams. Teams helped us to collaborate more through its call and document sharing features."
- "Performance-wise, Office 365 needs a lot of bandwidth. The problem is, the solution requires very high bandwidth and internet usage. Meaning, the desktop application consumes a lot of internet data. Sometimes, when the connection is slow, it won't work and it won't load. This is an area for improvement for Office 365."
What is our primary use case?
We use Office 365 for documents, like Microsoft Word, PowerPoint Excel, and Teams.
How has it helped my organization?
Microsoft Teams helped us to collaborate more. We use the call feature to communicate with colleagues, and the document sharing feature is a secure way of sharing through the cloud.
We use it more for Word, Excel, and PowerPoint. With the addition of Teams, which is an added feature that I like.
What is most valuable?
In terms of the most valuable feature, I use Word, PowerPoint, Excel, and Teams, but Teams is new for me.
What needs improvement?
Performance-wise, Office 365 needs a lot of bandwidth. The problem is, the solution requires very high bandwidth and internet usage. Meaning, the desktop application consumes a lot of internet data. Sometimes, when the connection is slow, it won't work and it won't load. This is an area for improvement for Office 365.
In the next release, I would like for Office 365 to be more of a finished product. It should have the ability to place calls and do system messaging. Those would be good improvements.
I would also like for the license to include a video cloning feature.
For how long have I used the solution?
I have been using Office 365 for five years.
How are customer service and support?
I never contacted Office 365 support because we have our IT support person who resolves any issue we face.
How was the initial setup?
The initial setup for Office 365 was straightforward.
What about the implementation team?
I deployed Office 365 in my machine. The deployment was really straightforward and took just half an hour.
What other advice do I have?
Before choosing Office 365, we didn't evaluate other options, because we've been using Microsoft Office products over the last decade. Microsoft Office is the preferred choice here in my country.
We purchased the Office 365 license for 40 users. The solution is deployed in a single location. We are only 55 people in the office.
My advice to others looking into using Office 365 is to go for it because it's an all-in-one solution that they can use for collaboration and other things.
My rating for Office 365 is eight out of ten. I would give it a ten if the bandwidth issue was solved because currently it uses up a lot of bandwidth, plus if they added more features to it.
Which deployment model are you using for this solution?
Public Cloud

Chief Information Officer at BeeBryte
Allows us to collaborate through Microsoft Teams and maintain a documentation repository
Pros and Cons
- "We use it for documentation management, to collaborate with Microsoft Teams, web calls, web conference calls, chats, and as a documentation repository mainly. We have an Office pack suite to be able to write documentation, make spreadsheets, and create PowerPoints."
- "The integration with mobile services is not so good. It's coming, but they could improve a lot."
What is our primary use case?
We use it to collaborate. We use it for documentation management, to collaborate with Microsoft Teams, web calls, web conference calls, chats, and as a documentation repository mainly. We have an Office pack suite to be able to write documentation, make spreadsheets, and create PowerPoints.
We are also using Microsoft Bookings to have calendars and automatic booking with people. At the moment, we are also using Microsoft Flow to be able to integrate between our CRM and SharePoint.
What is most valuable?
It's a very good suite. I did a survey, and our people are very happy using Microsoft.
What needs improvement?
The price is getting more and more expensive. They increased the price recently.
We are thinking about the way we are using our ERP and our CRM. The integration with ERP is not so good, but mainly due to the ERP, not due to Office. For integration with CRM, we are using Pipedrive.
The phone systems are expensive at the moment. The integration with mobile services is not so good. It's coming, but they could improve a lot.
For how long have I used the solution?
I have been using this solution personally for many years. My company moved to Office 365 in September.
What do I think about the stability of the solution?
It's magic. We had many issues with our previous open source solution Nextcloud, and now we rarely have any incidents. Those who are using this solution in my company are very happy with it.
How are customer service and support?
We installed the solution by ourselves and encountered some issues. We had some questions for technical support and they provided the answers, so it was quite efficient.
I would rate them a 5 out of 5 because they were very fast and precise.
Which solution did I use previously and why did I switch?
We were using the Nextcloud open source tool.
How was the initial setup?
It was quite easy considering our expertise, which was not very high. I trained my team thanks to Wiki and online documentation. It was okay. We did not use any partners.
What about the implementation team?
We did the installation in-house.
What's my experience with pricing, setup cost, and licensing?
For the moment, we are paying on a monthly basis because we are still adapting the support and how we want to proceed. I think we will move to paying for the annual license.
We are planning to switch from Office 365 to Microsoft 365, because we will deploy the security part and the configuration management part with Microsoft Defender and Intel.
What other advice do I have?
I would rate this solution 9 out of 10.
Some people might be disappointed with this solution because I discovered that for my team, it wasn't so easy for them to use at the start. I provided all the links for online training for Microsoft, but sometimes when we have new people, they don't know. The training is really well done. Everybody's able to manage and to use it after following the online training.

Assistant Administrator at PostsTechnohub Limited
High level support, flexible, and useful automation
Pros and Cons
- "The most innovative feature of Office 365 is the Power Apps, which allows us to automate literally everything that we want automated. For example, sending attachments to specific folders on SharePoint, adding people's SharePoint when certain apps are performed, or emailing certain people at certain instances, such as when you've done a follow-up with the CRM and you need a marketing email to be sent out at a particular point."
- "I rate the support of Office 365 a four out of five."

Junior Middle Office Officer at a financial services firm with 501-1,000 employees
Good applications, helpful for work, and can easily expand
Pros and Cons
- "It is stable."
- "Microsoft Word is a little bit left behind regarding the tools it has."
What is our primary use case?
In my workplace, we were mostly using Excel and Word to organize files, to be able to do tables, and handle general work. Mostly, these tools are the ones that we're using, however, it has a whole suite.
What is most valuable?
It's easy for you to create tables, organize your data, write some text, et cetera. If you want to apply for a job, you need to do, for example, your CV or cover letter, and you need Word to write in. The various applications and software available are excellent.
The implementation is easy.
It is stable.
The product can scale.
What needs improvement?
They are a little bit behind Microsoft Word in regards to the ability it has. It has many things you can add, and they keep adding tables, diagrams, and everything in other places. However, Microsoft Word is a little bit left behind regarding the tools it has.
For how long have I used the solution?
I’ve been using the solution for four years now.
What do I think about the stability of the solution?
The solution is stable and reliable. The performance is good. There are no bugs or glitches.
What do I think about the scalability of the solution?
It is a scalable product. You can expand it as needed.
We have more than 200 people on the solution currently.
How are customer service and support?
I’ve never directly dealt with technical support. I’m not sure how helpful or responsive they are.
Which solution did I use previously and why did I switch?
I did not use a different solution previously. It was my first choice, and I went with it.
How was the initial setup?
The initial setup is very straightforward. It’s not complex. It’s not difficult.
What about the implementation team?
I didn't handle the setup myself; someone else handled the implementation. I’m not sure exactly who was involved.
What's my experience with pricing, setup cost, and licensing?
I’m not sure of the exact cost. In the past, it might have been free. However, now, people do need to pay in order to use it.
I would put the pricing around two out of five. It's not the cheapest price per se. However, due to what it offers, it's actually worth the money.
What other advice do I have?
I am a customer and end-user.
I’m not sure which version of the solution we’re using. I use both cloud and on-premises deployments.
If you do not think about the money you have to pay to activate it, the tool offers good value and many applications, making it worth it.
I’d rate the solution nine out of ten. There’s still room for improvement. However, it’s pretty good.

Associate Vice President - Office of Strategic ManagementVice President - Office of Strategic Management at Sakthi Finance Ltd,
Feature rich, great for collaboration, and reasonably priced
Pros and Cons
- "There's a lot there in terms of apps and features."
- "We have found that, with Teams, if you are including one more person who is not in the company ecosystem, supposedly I'm inviting them as a guest in the chat. However, when I do that, I can't share files."
What is our primary use case?
We use this solution alongside Sharepoint and Teams.
It's primarily used for collaborative work. We use Teams, for example, to stay connected. Word we are using as a word processor. Then for exchanging emails we are using Microsoft Outlook. There are also certain basic analytics that we are using this Excel. We're taking advantage of the whole suite of tools.
What is most valuable?
It's a good solution in general. It's very feature-rich.
The product is a very good collaborative tool.
We are using the entire Microsoft product, including Outlook, Word, Excel, and PowerPoint. Apart from, them, we are also using Teams. There's a lot there in terms of apps and features.
The Channels and Microsoft Teams are the most valuable aspects of the product.
The initial setup is simple.
It is a very stable product.
You can scale the solution if you want to.
The cost of the product is not overly expensive.
What needs improvement?
We find that there is an abundance of features. Nothing is missing for us right now.
We have found that, with Teams, if you are including one more person who is not in the company ecosystem, supposedly I'm inviting them as a guest in the chat. However, when I do that, I can't share files.
For how long have I used the solution?
I've been using the product for the last two years. It hasn't been too long just yet.
What do I think about the stability of the solution?
The solution is stable. There aren't bugs. It's not glitchy. It doesn't crash or freeze. it's reliable.
What do I think about the scalability of the solution?
The product can scale. It's not an issue.
Not everyone is using it in our company right now.
How was the initial setup?
The setup has been pretty simple and straightforward. We haven't had any issues. It's not overly difficult.
What's my experience with pricing, setup cost, and licensing?
We are using the Enterprise Edition. We pay a yearly subscription fee on a per-user basis. It's reasonably priced.
What other advice do I have?
I'm a customer and an end-user. I don't have a specific business relationship with Microsoft.
It's all cloud-based. Therefore, we are always using the current version. It's a product that automatically updates itself.
Before using Microsoft Office 365, some sort of familiarity is required. Most people are aware of Word or Excel or PowerPoint, however, if they're using Teams, they should have some sort of in-field training.
I'd rate the solution eight out of ten. It has all t business tools that most companies require to run a business effectively. It is useful.

Executive Director at Onsearch
Presents information in a clear way for users and provides a good ERP for services but not for logic systems
Pros and Cons
- "The way the ERP presents information for the user is very good."
- "Normally, they have a way to work with specific developments, and I think they shouldn't allow the partners to make some changes they have made. When I have a client with a lot of changes, we have a problem with that because there aren't rules to develop inside the ERP, so you can do anything."
What is our primary use case?
I am using the new version, which they launched at the beginning of this year in Portugal. Business Central is the new version of the ERP for Microsoft.
The solution can be deployed on a public cloud and on-premises.
My company implements the solution, but the clients I do projects for usually have 50-60 users.
What is most valuable?
The way the ERP presents information for the user is very good.
What needs improvement?
I'm working with logistics a lot, and I'm seeing that the Business Center is not so good because I've been working in IT since 1984, so I have some experience in logistic systems. Three years ago, I had a project with a big client here in Portugal and I started using Microsoft Navision, which is the old version of Microsoft ERP. Now we are changing to Business Center, but it's not very good.
I think Office 365 is a good ERP for services but not so good for businesses, for industries, or for logistic systems. Those areas could be improved.
I'm not happy with how Microsoft Office 365 works. Normally, they have a way to work with specific developments, and I think they shouldn't allow the partners to make some changes they have made. When I have a client with a lot of changes, we have a problem with that because there aren't rules to develop inside the ERP, so you can do anything. I think that's not a good point.
I think SAP is very well prepared for that compared to Microsoft because it has the rules that departments have to follow. So, there should be more rules regarding restrictions for partners.
Procurement could also be improved.
For how long have I used the solution?
I have been using this solution for about three years.
What do I think about the scalability of the solution?
The scalability depends on the service area. For example, the scalability is good for the public sector, banks, and companies that are doing projects. For businesses like that, it's very useful. But for industrial and logic sectors, it's not scalable.
There are some simple ERPs that are much better than Microsoft Navision and Business Center. For scalability, SAP is much more powerful than Microsoft.
How are customer service and support?
I would rate technical support 4 out of 5.
Which solution did I use previously and why did I switch?
I worked with SAP for three years. For maybe 15 years, I worked with another Portuguese ERP.
I switched to Microsoft because I started working for a multinational company. The problem is that for software that is made locally in Portugal, if you start a project with a company, you are stuck with that company. You can't change solutions, so you have a big investment in that kind of process.
I think it's better to work with international products, because if you don't like that partner, you can switch to another partner. I think that is the best reason for one company to choose software that is implemented with lots of tech companies, because you can change and use another company.
How was the initial setup?
Initial setup is very easy.
What's my experience with pricing, setup cost, and licensing?
Some clients are starting to choose to pay monthly, and I think it's easier for them to understand the impact of the cost to the company.
I would rate the solution 3 out of 5 for the price. I think Microsoft presents a good solution concerning the price.
What other advice do I have?
I would rate this solution 5 out of 10.
For someone who wants to implement this solution, my advice is to ask your company to study the business and the needs of the project really well before choosing it.
When a company wants to buy a solution, they usually don't understand what they want. They know they have some reasons to change or buy a new solution, but normally they are not very well prepared for a change. I think companies should make a study and then choose the best solution for their company's needs.
