IT Manager at Cerberus IT Solutions
Quick setup, useful online archiving, and highly scalable
Pros and Cons
- "The most valuable feature of Microsoft Exchange Online is if you have people that are geographically distributed from each other is good. For example, if you have people in the United States, Europe, Africa, Asia, and Australia, having an online solution works best because then you can reach the scale of the data centers that are available by Microsoft. Additionally, if you're only going to have two to three people using the solution the cost is a lot less than having an onsite server and licensing. It is highly beneficial in these areas."
- "The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."
What is our primary use case?
Microsoft Exchange Online is used for emails and it does a fantastic job.
The only reason why you would choose an online solution is the company that you're working at is they do not want to have an onsite server. The companies that want something on-site would choose the on-premise version.
What is most valuable?
The most valuable feature of Microsoft Exchange Online is if you have people that are geographically distributed from each other is good. For example, if you have people in the United States, Europe, Africa, Asia, and Australia, having an online solution works best because then you can reach the scale of the data centers that are available by Microsoft. Additionally, if you're only going to have two to three people using the solution the cost is a lot less than having an onsite server and licensing. It is highly beneficial in these areas.
The online archiving option works well. If you have a lot of emails and you want to keep them indefinitely, then you can use the online archive. It's available permanently and you can store quite a bit of email inside it.
For how long have I used the solution?
I have been using Microsoft Exchange Online for approximately four and a half years.
What do I think about the stability of the solution?
The stability of the solution is good. I've only had an issue with it once or twice, but that was due to undersea cable damage.
What do I think about the scalability of the solution?
Microsoft Exchange Online is highly scalable.
We have a lot of users using this solution.
How are customer service and support?
The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience.
I rate the support from Microsoft Exchange Online a three out of five.
How would you rate customer service and support?
Neutral
How was the initial setup?
The initial setup of the cloud version is similar to the on-premise version. You can have a straightforward or semi-complex deployment. Cloud deployments do not become as complex as the on-premise version, but they can, depending on how it is used.
The deployment of the solution only takes five minutes. It is very useful when deploying from scratch. As soon as you have the domain up and running it is complete and ready to go.
What's my experience with pricing, setup cost, and licensing?
The license for the solution is cheap, but it could be more affordable in the long term.
What other advice do I have?
We have one level two or level three engineer that does the deployment and maintenance of the solution. The online version does not require a lot of people to run it.
I recommend this solution to others and they will not regret it. They should not use other solutions.
I rate Microsoft Exchange Online a nine out of ten.
Which deployment model are you using for this solution?
Public Cloud

CDO at SGROUP
Convenient, easy to install, and scalable when deployed on the cloud, but has too many products integrated with it that it has now lost focus
Pros and Cons
- "What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs. Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted."
- "What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like. Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement. I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one."
What is our primary use case?
We're using Microsoft Exchange Online for our emails.
What is most valuable?
What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs.
Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted.
What needs improvement?
What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like.
Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement.
I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one.
For how long have I used the solution?
I've been using Microsoft Exchange Online for more than ten years.
What do I think about the stability of the solution?
Microsoft Exchange Online is a stable product, in particular, when it's on the cloud. It's stable when it's dependent on the cloud, but if it's deployed on-premises, Microsoft Exchange Online is not stable.
It's a very old product with the same code, even on Windows. Nothing's changed, and my company is using Windows NT for Microsoft Exchange Online with Unix as the code.
What do I think about the scalability of the solution?
Microsoft Exchange Online is a scalable solution.
How are customer service and support?
We haven't used the technical support for Microsoft Exchange Online.
Which solution did I use previously and why did I switch?
Microsoft Exchange Online is the first service I've used, and all the new services in the market are a little bit different from this solution. Microsoft is a very old company, and almost all of my colleagues started with Microsoft products, so it's just natural to continue using Microsoft Exchange Online.
How was the initial setup?
Microsoft Exchange Online is easy to install.
What's my experience with pricing, setup cost, and licensing?
There is a license for Microsoft Exchange Online and I have information on that, but there have been so many changes to the licensing and it's a completely different story nowadays. Microsoft has been pushing users to buy a package of products under one license. Users are becoming more dependent on Microsoft rather than independent, that you can't decide anymore, and from my point of view, that is bad.
Which other solutions did I evaluate?
My company evaluated Qualitas, Unix, HP, and IBM.
What other advice do I have?
In my company, Microsoft Exchange Online is deployed both on the cloud and on-premises.
More than two thousand people use Microsoft Exchange Online in my company of four thousand employees.
At the moment, there's no plan of increasing usage of the product because of the current crisis.
In terms of whether I would recommend Microsoft Exchange Online to others, with the integration it has, it depends on the focus of the company. For small markets, Microsoft Exchange Online is "too big" because it has a lot of services and you'll be paying for services provided in the package, with some you don't get to use. For end users, this would be difficult, but for companies, especially bigger ones that would have a choice, Microsoft Exchange Online is a good product. My recommendation would depend on the case because every user is different, for example, the purpose is different, the business is different, etc.
My rating for Microsoft Exchange Online is seven out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Managing Director at ProQuanta
A stable solution for managing suites with a collaboration feature
Pros and Cons
- "One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good."
- "The solution’s pricing could be better."
What is our primary use case?
We use the solution to manage calendars and the entire online and on-premises suite. It is used in large corporate banks.
What is most valuable?
One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good.
What needs improvement?
The solution’s pricing could be better.
For how long have I used the solution?
I have been using Microsoft Exchange Online as a reseller for three to four years.
What do I think about the stability of the solution?
The collaboration speed has some issues, but it is stable.
I rate the solution’s stability an eight-point five out of ten.
What do I think about the scalability of the solution?
The solution is scalable. When you reach certain volumes, the default limits on the packages essentially allow you to use the full spectrum anyway.
The solution’s packaging makes it difficult to scale to the enterprise level without significantly upgrading the packages and negotiating higher limits on certain things, such as API calls, to accelerate data transfer.
Around 3000 users are using this platform.
I rate the solution’s scalability a nine out of ten.
How are customer service and support?
Microsoft technical support is making some improvements, but it can still be time-consuming to get an answer to a basic question. I often find it easier to troubleshoot the problem myself.
How was the initial setup?
The initial setup is straightforward and takes around a week to complete.
Exchange Online deployments can be complex, especially when migrating existing data from on-premises to the cloud. Much planning and preparation is involved, and the process can be lengthy.
What's my experience with pricing, setup cost, and licensing?
The product is expensive and has an annual subscription.
Which other solutions did I evaluate?
It's difficult to compare Exchange Online to other solutions because of its unique feature set and collaboration capabilities. For example, Google SaaS is quite limited compared to Exchange Online.
What other advice do I have?
We require a full-time team of four or five engineers across different divisions to look after this solution.
I recommend this solution. You’ll find it difficult to find a better solution with all the same features at the same price point. Most other competing solutions don't have the same feature set for the price.
Overall, I rate the solution an eight out of ten.

Support Engineer at CREST
Easy to set up with good pricing and good access
Pros and Cons
- "Technical support is helpful."
- "We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet."
What is our primary use case?
The solution is basically for access and it provides the ability to just receive and send emails. It also works with calendars and contacts and all of that.
What is most valuable?
The solution works very well. It's one of the best options available. The access it provides is good.
It has an easy initial setup.
Technical support is helpful.
It is scalable.
The solution is quite stable.
It has okay pricing.
What needs improvement?
We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet.
I haven't used the solution for too long and need more time to see if other improvements are needed.
The cost could be a bit lower.
We've had clients complain about some aspects of Microsoft Bookings. It would be great to have an opinion platform back on Bookings.
For how long have I used the solution?
I've been working with the solution for six months.
What do I think about the stability of the solution?
The solution is stable. The only thing that is not so stable is Microsoft Teams. However, Exchange has good reliability. It doesn't crash or freeze.
What do I think about the scalability of the solution?
I love the scalability. I like that I can start wherever I am and scale up or down. I love the flexibility it gives us.
We have about 50 people on the solution presently.
How are customer service and support?
Technical support is great. I've raised some requests, and they were helpful and responsive.
Which solution did I use previously and why did I switch?
We did not previously use a different solution.
How was the initial setup?
I took part in the implementation process. The initial setup is pretty straightforward and simple.
The deployment didn't take more than an hour.
We have two administrators that are global admins. We have one admin that is specifically for Exchange.
What's my experience with pricing, setup cost, and licensing?
The pricing is fine. I've discussed this with customers, and they have found the price point to be fair. When you compare it to others, like Google, it is competitive. If it could be lower, of course, it would be ideal.
The solution costs $12 to $16 per user per month.
What other advice do I have?
I currently support Microsoft products. I don't sell Microsoft. They also have my test environment, where I test a few things.
Everything is available in the documentation. It's a great solution. Everything you need is there.
Overall, I'd rate the solution nine out of ten. There's always room to improve still.
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?
Microsoft Azure

Good documentation, excellent support, and an easy initial setup
Pros and Cons
- "The solution generally works well. We can send and receive emails just fine."
- "The pricing could be a bit lower."
What is our primary use case?
We primarily have it for our customers. We primarily use the solution with mobile access, and it's just for having the ability to send and receive emails. It also works with calendars and contacts.
What is most valuable?
The solution generally works well. We can send and receive emails just fine.
It is useful and easy to use.
The initial setup is straightforward.
It's scalable.
The solution is stable.
Technical support is great.
The solution offers great documentation.
What needs improvement?
We'd like to have the ability to recall emails.
I've just used it for six months and am still working to understand the general landscape.
The pricing could be a bit lower.
Certain items have been removed from Mircosoft Booking. They should re-add the capabilities it had before.
For how long have I used the solution?
I've been using the solution for six months at this point. It's been less than a year.
What do I think about the stability of the solution?
The stability of this solution is pretty good. We do find, however, that Microsoft Teams is unstable. Exchange, so far, has been great.
What do I think about the scalability of the solution?
This solution is definitely scalable. We haven't had any issues at all. I love that I can start with what I actually need and scale up or down as needed from there.
Right now, we have about 50 people on the solution.
How are customer service and support?
Technical support is great. We're happy with its capabilities. There is also useful documentation that can help users understand the solution.
Which solution did I use previously and why did I switch?
We are not using any other solutions.
How was the initial setup?
The setup is pretty straightforward. It's not overly complex. It just took about an hour to set up everything. We simply had to go through some documentation. After we did that, it was very easy.
We have two administrators that can handle the management. They are global Microsoft admins. We also have an Exchange admin specifically.
What's my experience with pricing, setup cost, and licensing?
The pricing is fine. I've had similar conversations with my customers, and we've found the cost is fair. However, if it could be lower, that would be a plus.
The cost is around $12 to $16 per user.
What other advice do I have?
I'm an end user. We also currently support Microsoft products.
Everything is available in the documentation, and there is great support. It's worth the price, and other users would enjoy having it.
I'd rate the solution nine out of ten.
