Infrastructure Architect at a tech services company with 5,001-10,000 employees
I really like the unlimited archiving, the hold and redemption policy functionality.
Pros and Cons
- "Tech support has been great, when necessary."
- "It is a stable, and highly scalable product."
- "Migration can be an issue if you do not have a good audit process."
- "Functionality wise, I can't really say it's improved from Exchange Online, I think it's not so much change on-premise. It's about the same. Other than that, it's the extra features that make a difference, really"
What is our primary use case?
We primarily use this as a business solution for service desk, mails and the automation process. This year, we did a migration process from Exchange to Exchange Online, and that included everything that goes with that.
How has it helped my organization?
A better approach for them to use Exchange Online was to have the host serve us in a cloud service. Functionality wise, I can't really say it's improved from Exchange Online, I think it's not so much change on-premise. It's about the same. Other than that, it's the extra features that make a difference, really.
I think with Exchange, it's a lot of integration functionality with the Skype for business. It's quite accepted if you like an almost-defective standard. Especially in the region that we email them, definitely in the Asia-Pacific region or at least Oceania region. It's really easy to use. The the room and shared mailbox functionality that people use, it just all really works well together.
What is most valuable?
The features that are most valuable are: unlimited archiving, the hold and redemption policy functionality.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
There were no issues of stability at all. I have not experienced issues of connectivity or backend issues at all.
What do I think about the scalability of the solution?
This is a highly scalable solution. We implemented it for 160 users. All the space you need is there. You could quickly grow it. All the functionality is there. You've got the power shelf or bulk work that you need to do. There are no issues.
How is customer service and technical support?
Tech support has been great, when necessary. There is a quick response time. The specific issues we were dealing with were to verify an end-case. We did have to go through three or four different people, who gave us different answers. But, we finally got a response from a tech specialist who plainly told us that we could not do what we wanted to do. We found the tech support highly intelligent and knowledgeable.
How was the initial setup?
Initial setup was straightforward.
What was our ROI?
We worked out the investment was a worthwhile investment that saved itself in about eight months. The investment in the project to get it across would pay for itself by reducing the on-premise Exchange costs. There is a definite return on investment by using this solution.
What's my experience with pricing, setup cost, and licensing?
Regarding the pricing and licensing of the solution, it's great. I think it's just awesome. There's no argument about how much value you get on the per user, for user expenditure. It's really great, I don't have any issues with it. I think it's excellent.
What other advice do I have?
Make sure you've got a set user base from all areas of the business because everyone in different departments uses the mail functionality differently. Just make sure you have a really good audit process of what your current environment really is doing before you do your migration.

Tech Lead at a tech services company with 1,001-5,000 employees
The management is very simple. The unlimited storage is a nice feature.
Pros and Cons
- "It is a reasonable solution."
- "It is very manageable."
- "Its most valuable feature is the unlimited storage. It also has very little downtime."
- "For example, recently there were some spam incidents that Microsoft does not currently mitigate because they have another paid solution to do so. It would be nice to integrate the security and the anti-spam (i.e. the fake links, etc.) along with the Exchange Online default."
What is our primary use case?
Our primary use case is for a mailing solution. It is an amazing solution that we have been using for quite some time.
How has it helped my organization?
The management is very simple, using Exchange Online. So basically you just start a license. So that way, management is very simple.
What is most valuable?
Its most valuable feature is the unlimited storage. It also has very little downtime. In addition, there is a lot of security which comes with this product. I do not think of integration of anything without this solution.
What needs improvement?
There is still room for improvement. For example, recently there were some spam incidents that Microsoft does not currently mitigate because they have another paid solution to do so. It would be nice to integrate the security and the anti-spam (i.e. the fake links, etc.) along with the Exchange Online default.
For how long have I used the solution?
More than five years.
What do I think about the stability of the solution?
I have not experienced any issues with stability of the solution.
What do I think about the scalability of the solution?
I have not experienced any issues with the scalability of the solution.
How are customer service and technical support?
I think the tech support was very good. There are different types of support provided. We had some recent issues regarding anti-spam.
Which solution did I use previously and why did I switch?
We upgraded from earlier versions of Exchange to the current Exchange Online. We noticed that the last version had a limitation of data storage. With the current Exchange Online, if I have a license, I can have unlimited storage. So, I do not have to worry about anything, and I can keep all of the emails on the cloud, accessible from all of my devices. It is also a welcome integration with all Microsoft Suite products. This is a nice added advantage.
How was the initial setup?
The initial setup was not that complex. If you have experience with Microsoft Exchange, then the setup of Microsoft Exchange Online is still fairly straightforward.
What's my experience with pricing, setup cost, and licensing?
I think it is a very manageable and reasonable solution. There are different licensing agreements that you can choose, according to your company's needs. In general, I think this is a pretty reasonable solution.
Which other solutions did I evaluate?
We started with Exchange, so we did not look at other solutions.
What other advice do I have?
Exchange Online is the best solution currently available in the market. And we see from our experience that people are moving from different mailing solutions to Exchange Online. It works very well with your Microsoft Suite of products such as : Word, Excel, PowerPoint, and Outlook.

Allows collaboration and file sharing with a bigger inbox
Pros and Cons
- "Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing."
- "The demo version we were provided had issues with emails bouncing or being delayed."
What is our primary use case?
I use MS Exchange Online for corporate emails.
How has it helped my organization?
Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing. It also gives you a bigger inbox per account (50GB) than Gmail.
What needs improvement?
The demo version we were provided had issues with emails bouncing or being delayed. This hasn't happened since we purchased licenses, but it shouldn't happen even in the demo.
For how long have I used the solution?
I've been using this solution for eight years.
What do I think about the stability of the solution?
Exchange Online's stability is good once you have a license - in pre-licensing trial mode, it's not so good.
What do I think about the scalability of the solution?
The scalability is good.
How are customer service and support?
I wasn't happy with the support from the partner I was directed to and would prefer to get direct support from Microsoft. Microsoft's technical support is good.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is a little complex because you don't get any assistance - you just go to a site and do it yourself. I would rate it as two out of five.
What's my experience with pricing, setup cost, and licensing?
The licensing price is ok, I'd rate it as four out of five.
What other advice do I have?
I'd give Exchange Online a rating of nine out of ten.

Delivery manager at a computer software company with 201-500 employees
Completely scalable and flexible
Pros and Cons
- "The solution offers complete scalability and flexibility."
- "The solution should have more integration with other platforms."
What is our primary use case?
I use the latest version.
The solution obviates the need for infrastructure. The model is pay-per-use. We are not talking about a single email but a complete collaboration suite. One gets very well integrated IT which is tightly stitched with collaborations. One can chat and field calls. As such, it is not only Exchange Online coming on, but Office 365 Suites, which Microsoft provides the users. This availability ranges from first-line workers to CEO level users, depending on one's requirements. All the industry needs are covered. One can take the model best suited to him and tailor his solution to his investment capacity needs.
This means that the solution offers complete scalability and flexibility. A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also options. The solution's handy. One can use it on his mobile, or any other devices, including multiple devices and single identity. So, the picture is comprised of many components.
What needs improvement?
The solution should have more integration with other platforms. It is more integrated to the collaboration suite and other document management systems.
For how long have I used the solution?
I have been using Microsoft Exchange Online for the last couple of years.
What do I think about the scalability of the solution?
The solution boasts complete scalability.
How was the initial setup?
As the solution is cloud-based, there is no installation required. There is no need to worry about its applications and no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
What's my experience with pricing, setup cost, and licensing?
The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also posibilities.
What other advice do I have?
The solution is an SaaS cloud-based solution.
There are a thousand-plus users making use of the solution in our organization.
I would recommend the solution to others, although this depends on the capacity one is interested in and whether he utilizes another solution. For someone who wants the complete bouquet of the solution, he can go with Office 365. There are others solutions which are geared to one who is only interested in email capabilities. There are many cloud-based solutions available, although these vary with the needs of the organization. Office 365 is geared towards someone who is looking for a complete collaboration suite. Someone who is not looking for this is advised to go with another solution.
I rate Microsoft Office Exchange as an eight to nine out of ten.
