We use Microsoft Exchange Online for sending emails between companies.
System and Network Engineer at Pointec
Reasonably priced and used for sending and receiving emails between companies
Pros and Cons
- "The best thing about Microsoft Exchange Online is that it's integrated with the Outlook application."
- "The configuration of the solution's on-premise version is a little bit difficult, and its troubleshooting is more difficult than the installation itself."
What is our primary use case?
What is most valuable?
The best thing about Microsoft Exchange Online is that it's integrated with the Outlook application. Google also has the same solution, but Microsoft is more integrated with Outlook because the Outlook application is its own product.
What needs improvement?
The configuration of the solution's on-premise version is a little bit difficult, and its troubleshooting is more difficult than the installation itself. You need to configure load balancing, high availability, databases, and user policy to complete the configuration. If anything happens, it will take a very long time to troubleshoot.
For how long have I used the solution?
We have been using Microsoft Exchange Online for ten years.

885,376 professionals have used our research since 2012.
What do I think about the scalability of the solution?
All of our users are using the solution.
How are customer service and support?
The technical support for the solution's on-premise version is a little bit slower.
What's my experience with pricing, setup cost, and licensing?
The solution's pricing is reasonable. It's not very cheap, but it's reasonable somehow. It depends on the plan because the cloud users do not buy Microsoft Exchange Online separately. They take a Microsoft 365 plan. It's very rare that a customer comes and says that he needs only emails.
Customers purchase the plans of Microsoft Office, including Windows license from the cloud, Microsoft Teams, OneDrive, and SharePoint. All these products come with the bundle of Microsoft 365. So, the pricing depends on the plan you are going through.
What other advice do I have?
Most of the customers want to send emails securely. Things changed when the cloud came. Microsoft Exchange Online is still important as on-premise for the government of Saudi Arabia because they have a policy that they don't allow their data to go on the cloud.
Most of our customers use Microsoft Exchange Online, which is a great solution because it reduces the headache of technical support. Very few users who deal with the government still use the solution's on-premise version. I would recommend the solution to other users to send and receive emails. It's a very great solution.
Overall, I rate the solution ten out of ten.
Which deployment model are you using for this solution?

IT Lead at CMH
An easy, simple, and secure product with an excellent message-tracing feature
Pros and Cons
- "Message trace is the most valuable feature of the product."
- "The interface is a bit confusing."
What is our primary use case?
The product is used to create email addresses. We can also create groups and distribution lists. The product also provides email forwarding features. We can create rules, monitor the flow of emails, and trace messages. We can use connectors on the platform for email security and email signature.
What is most valuable?
Message trace is the most valuable feature of the product. We can get a customized report on what is happening in our environment. We can trace all the emails, understand what happened, and get information on how they reached the user and the hops before delivery. It is very interesting.
We can also know how many deliveries failed and are pending in the queue and customize our reports how we want them to be. The product is very easy, simple, and secure. It is available everywhere because it is cloud-based.
What needs improvement?
The solution should have a better interface. The interface is a bit confusing. It should be more simple. The product should also improve the email flow. The rules are a bit complicated compared to the previous version. The previous version was much easier, and the latest one is more complicated.
For how long have I used the solution?
I have been using the solution for four to five years.

How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I was using Lotus Notes five to six years ago. It was centrally based in our head office. I didn’t contribute to it. Later, when I applied to have my own email solution, I chose Microsoft.
How was the initial setup?
The solution is very easy to set up. We just have to enter the username and password and start using it. We can deploy emails to end users within five to ten minutes. The product is cloud-based.
What was our ROI?
In our business, everything is done by email applications, Microsoft Excel, and Microsoft Word. So, we get a 60% ROI on the solution.
What's my experience with pricing, setup cost, and licensing?
We pay a yearly licensing fee for the solution. The cost depends upon the plans we choose and the types of applications we want to use. We have a three-year deal with Microsoft to get a good price for the product. They are very willing to revise the price, accompany us for the setup, and give us a framework. They are very impressive to work with. There are no additional costs associated with the product.
What other advice do I have?
I am using the latest version of the solution. Most businesses and users are using Microsoft for email business. I would recommend the solution to others. Overall, I rate the solution a ten out of ten.

Director of IT ISO at a financial services firm with 51-200 employees
Quick to deploy, easy to set up, and works with minimal issue
Pros and Cons
- "The solution is very easy to set up and quite quick to deploy."
- "It does what it's supposed to do with minimal issues, and the solution is very easy to set up and quite quick to deploy."
- "When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."
- "When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."
What is our primary use case?
We primarily use the solution for email and calendar functionality.
What is most valuable?
It works. It does what it's supposed to do with minimal issues.
It's one of the products that Microsoft has absolutely done its very best with.
The solution is very easy to set up and quite quick to deploy.
What needs improvement?
Right off the top of my head, I can't think of anything that I would change to improve Exchange.
The pricing could always be better.
Right now, I'm writing documentation to upgrade the existing Exchange and Active Directory from 2016 to 2019.
When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid. At present, once you establish a hybrid organization between cloud and on-prem, there's no way to undo it. Fixing that would be most beneficial. At the last organization I was at and did a migration, I had 31,000 users, and my largest mailbox was 90 gigs. It took three months to complete the migration.
We had no choice but to put it into hybrid mode due to the period of time. The MX record can only exist in one place. Therefore, you can't route mail from one system to another system. All the mail had to be routed through the on-prem and then synced from the on-prem to the cloud until everything was in the cloud. Then we were able to move the MX record from being on-prem to being in the cloud. Then all mail could be received in the cloud. However, then there was no way to tear down the Exchange organization on-prem. We are still left with a server, server maintenance, licensing, OS upgrades, patching, and everything on the on-prem server. The on-prem server is literally sitting there doing nothing except filtering air in the data center, costing me power, time and cooling. Therefore, fixing that would be awesome.
For how long have I used the solution?
I’ve used the solution throughout my career - for over 30 years.
How are customer service and support?
Typically, by the time I open a ticket, and they get back to me, I've figured out how to fix it. I don't call them until I'm really stuck.
They're not very good. I have had one of their technicians call me back more than once, and I'll go, "I figured it out, I fixed it." They flat asked me, "Well, how did you fix it?" I'm like, "You're Microsoft. You figure it out." They may not have the best understanding of the system.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I've used Exchange my entire career. My best friend is currently trying to get rid of Lotus Notes where he's at. He's been working on that for a year now, and it just doesn't seem to want to go away. I've always been with this product. I did a bunch of work with GroupWise and got GroupWise out of the environment and so forth - replacing that with Active Directory. However, that really didn't have a mail component to it.
How was the initial setup?
The initial setup is very straightforward. It only took a few hours to deploy.
What's my experience with pricing, setup cost, and licensing?
The pricing is always something that could be better. We always like to work towards protecting our budget.
I know what the cloud cost per user is. I don't have what the on-premises costs are.
What other advice do I have?
I’m a customer. I don't have any direct relationship with Microsoft.
I’d rate the solution a nine out of ten.
It's an excellent product. It's an excellent mail system. It does exactly what it's supposed to do. If you are under 5,000 employees, I would say that Microsoft 365 is the way to go. If you're over 3,000 or 5,000 employees, I would have some serious conversations about on-prem versus cloud. Once you get over about 3,000 or 5,000 employees that are mail users, the cloud really starts to get much more expensive than on-prem.

Solutions Architect at Vvolve management consultants
An easy-to-use platform providing mail tagging and other top-notch security measures
Pros and Cons
- "The solution is stable."
- "The cost is very high, and not every customer can afford licenses."
What is our primary use case?
It's a messaging card with the assembly solutions. I manage multiple platforms and upgrade and migrate the environment on-prem to online.
What is most valuable?
It is an easy-to-use platform. It provides both browser-based and desktop versions, accessible through a single license or up to three licenses. Additionally, with enterprise plans, you can use desktop licenses. It includes mail tagging and other top-notch security measures. You can manage mailboxes and utilize many other features based on your needs. Shared mailboxes are also available and can be used freely.
What needs improvement?
The cost is very high, and not every customer can afford licenses. Many customers only require the desktop version, so they don't opt for desktop licensing. Also, Exchange lacks a tunneling system. We need to explore third-party solutions and tunneling systems.
They are improving the new version of Outlook. It's free, and we provide the desktop application. This can be quite resource-intensive on the desktop level. When you open Outlook, it heavily utilizes your internet connection, slowing down your email access. Another issue concerns security features. There have been reported bugs in Microsoft's security features where emails marked as spam may still get through, leading to concerns about spoofing.
For how long have I used the solution?
I have been using Microsoft Exchange Online for 11 years.
What do I think about the stability of the solution?
The solution is stable. However, some certain limitations and issues arise, particularly with the desktop application and related functionalities. Recently, Microsoft announced an issue with email invitations not functioning correctly in Exchange Online, leading to duplication and other disruptions.
What do I think about the scalability of the solution?
We must procure licenses and ensure we have everything required based on the requirements. However, this also depends on the network. For instance, scalability and other issues may arise if we have fifteen users and a network speed of ten Mbps from our ISP.
How are customer service and support?
I experienced an issue with Microsoft Exchange Online, where creations are typically sorted out within 15-16 days.
How was the initial setup?
I've worked on involved setting up Microsoft Exchange Online. We implemented DMARC, DKIM, and other essential email authentication protocols. Additionally, we focused on configuring API access to enhance security measures. We also redirected all mail services to Office 365, a standard procedure. Our approach included reconfiguring settings according to best practices for Exchange Online.
The deployment spans one month at maximum, depending on specific requirements. For me, it is crucial to meet all prerequisites, such as domain names, DMARC policies, certificates, and other necessary configurations. Once these are prepared, straightforward implementations can be completed within seven days, barring unforeseen complexities. Integration with licensing structures, email gateways, and potential hybrid environments adds further considerations. Understanding hybrid configurations is essential and tailored to meet client-specific needs for an optimal online deployment.
What's my experience with pricing, setup cost, and licensing?
All of that is managed within the pipeline. The cost-saving aspect involves reducing licensing requirements. For instance, if you have fifteen licenses, you must evaluate which licenses are unnecessary for non-required production. Reducing those licenses will reduce costs.
What other advice do I have?
The compliance features are crucial. We have options such as rights management, marking as confidential, and restrictions on sending emails. Additionally, we monitor tunneling systems for security threats such as malware and employ spam filtering and anti-spam measures. These practices are designed based on industry best practices and tailored to meet customer requirements, including regulatory compliance. Retention policies are also implemented online for five to ten years, depending on customer and regulatory requirements.
It can be integrated using the Graph API. Third-party tools like IronPort and Mimecast can also be integrated with Exchange Online. These integrations often utilize Azure APIs for connectivity.
It requires maintenance based on our needs. Unnecessary licensing can become an issue, especially in large environments with multiple users. Therefore, it's essential to manage licenses effectively, such as by removing licenses from groups based on usage. Regular maintenance involves disabling users, removing sync, and adjusting licensing accordingly. Security features like spam filtering should also be upgraded quarterly to ensure optimal protection.
I recommend using Microsoft Exchange Online because it offers a straightforward environment. Administrative tasks are easily manageable at the L1 and L2 levels. However, it's important to note that Exchange Online operates primarily through a UI-based control interface. If issues like data corruption occur on the backend, we lack direct control to fix them ourselves. In such cases, we must report the issue to Microsoft for resolution.
Overall, I rate the solution a nine out of ten.

What's my experience with pricing, setup cost, and licensing?
The product is very cheap. It is relatively affordable.
What other advice do I have?
If someone plans to use the solution, they must consider the number of users. They must choose the license model depending on their organization. The documentation must be put together in detail, and the right model must be chosen. Overall, I rate the tool a ten out of ten.
