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.

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

Assistant Manager Technical at Ironbridge Systems (Pvt.) Limited
Features like SharePoint Online allow for collaboration between our team members
Pros and Cons
- "We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good."
- "They should tighten their cloud security."
What is most valuable?
We use SharePoint Online for the collaboration of our team and for other desktop applications we are using in-house.
We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good.
What needs improvement?
They should tighten their cloud security. If you are using Microsoft Office 365, the responsibility of backup is not on the part of Microsoft. It is on the part of the customer. Microsoft Office should give some kind of built-in solution with the Office 365 subscription regarding the backup of their online mailboxes.
For how long have I used the solution?
My company has been a Microsoft Gold partner for the last 12 years. As soon as we became a Gold partner, we started to use Office 365.
What do I think about the stability of the solution?
It's stable.
What do I think about the scalability of the solution?
We can have different plans. If we are scaling, then obviously we can go for the enterprise plan and add an unlimited number of users to our Office 365 plan.
How are customer service and support?
Overall, technical support is very good. My colleagues reached out to Microsoft technical support many times for queries. They are very responsive.
How was the initial setup?
Setup was really simple. We migrated our customers from a different platform to Microsoft Office 365. There is a separate technical team. I designed the solution only.
What's my experience with pricing, setup cost, and licensing?
They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription.
What other advice do I have?
I would rate this solution 8 out of 10.
I would recommend Office 365. It's a global product, and overall they have a larger footprint in the world. We're a Microsoft Gold partner, so as soon as the customer moves to Office 365, obviously our business will also grow.

Provides a secure login and is intuitive but needs to be more user friendly
Pros and Cons
- "Intuitive and easy to use."
- "Using this solution is initially quite complicated."
What is our primary use case?
This product provides us with a secure login and enables us to gather information from our users. We are resellers and I'm a key account manager.
What is most valuable?
The design is intuitive and better than the solution we had previously used. Once it was configured it was very easy to use.
What needs improvement?
This is a single solution and if it's the first time you've used Exchange, it's extremely difficult to get users onboard because it's much more complicated than you'd have with 365, for example.
For how long have I used the solution?
We've only just started using it, it's been a week.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is scalable, we have around 100 users.
How was the initial setup?
The initial setup was complex and took us around two weeks. We deployed in-house; it's in the cloud so there's no maintenance required.
What other advice do I have?
The problem is that it's a little complicated when you first start using it. It's important to read up about it and figure out whether it's the right solution for you.
I rate the solution seven out of 10.
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

Program and performance manager at Ethio Telecom
Simple, easy to use, scalable, and easy to install
Pros and Cons
- "Microsoft Exchange Online is very simple and easy to use."
- "For non-technical people, some configurations might be a little bit difficult. We can use it on our laptops or our portable devices like mobiles and others gadgets, but we have had repeated problems with syncing. That is, when using different gadgets and devices, there are issues with syncing. The configuration could definitely be improved."
What is our primary use case?
We use SharePoint and Active Directory, meaning that all telecom users and customers are authenticated. We use it as a gateway.
What is most valuable?
Microsoft Exchange Online is very simple and easy to use.
What needs improvement?
For non-technical people, some configurations might be a little bit difficult. We can use it on our laptops or our portable devices like mobiles and others gadgets, but we have had repeated problems with syncing. That is, when using different gadgets and devices, there are issues with syncing. The configuration could definitely be improved.
Technical support is needed for any log-in credential problems and other related issues.
For how long have I used the solution?
I've been using it since 2008.
What do I think about the scalability of the solution?
It is scalable. We have around 16,000 users in our company.
How was the initial setup?
There are no problems with the installation, but when you finish the installation and get to the authentication part of the log-in, there may be problems. It needs improvement.
A team of not more than ten is needed for deployment and maintenance.
What's my experience with pricing, setup cost, and licensing?
We have yearly licensing costs.
What other advice do I have?
I would rate Microsoft Exchange Online at eight on a scale from one to ten.
Which deployment model are you using for this solution?

Performs well, and is simple to install, but the technical support could be improved
Pros and Cons
- "Microsoft Exchange Online's resiliency is its most valuable feature."
- "We use different software for email spoofing filters and similar functions because Exchange is quite limited in this area."
What is our primary use case?
We use Microsoft Exchange Online for email.
What is most valuable?
Microsoft Exchange Online's resiliency is its most valuable feature.
What needs improvement?
We use different software for email spoofing filters and similar functions because Exchange is quite limited in this area.
Email spoofing, monitoring, email marketing, and email broadcast have limits or are governed by the number of emails you can send, in any given hour.
I would like to use it as my email broadcasting method.
For how long have I used the solution?
I have been using Microsoft Exchange Online for three years. We were migrating before Covid.
What do I think about the stability of the solution?
Microsoft Exchange Online is quite stable.
I would rate the stability a nine out of ten.
What do I think about the scalability of the solution?
I would rate the scalability of Microsoft Exchange Online an eight out of ten.
How are customer service and support?
I would the technical support a five out of ten.
How was the initial setup?
The initial setup is pretty straightforward.
What other advice do I have?
Make sure that's what you want to use. Consider your requirement. And if you want to scale to, say, an enterprise-class, you should be aware of certain of Exchange online's limits.
I like it, I would rate it a seven out of ten.

ICT LAN Administrator at Zambia Revenue Authority
Scalable hosted messaging solution that highlights mailboxes that have experienced a violation
Pros and Cons
- "The best part of this solution is the security it offers."
- "This solution involves a lot of work for an administrator. It is not always easy to find exactly what you are looking for within the system."
What is our primary use case?
We have 2,000 users supported by this solution.
What is most valuable?
The best part of this solution is the security it offers. Where we are able to determine which mailboxes have been blocked, or which mailboxes cannot be allowed to send traffic because of a violation.

This is a stable solution.
