Pros and Cons
- "The most valuable feature of Microsoft Exchange Online is it helps the IT department with problems."

What do I think about the stability of the solution?
We can experience some glitches but this could be the fault of our ISP and not the Microsoft Exchange Online. Other than this experience it has been stable.
What do I think about the scalability of the solution?
The scalability of Microsoft Exchange Online is good as long as you are paying for the approximate usage.
We have approximately 800 people using this solution in our group. We have many types of users, such as managers and architects.
How are customer service and support?
I have not used the support from Microsoft Exchange Online.
How was the initial setup?
The initial setup of Microsoft Exchange Online is very simple.
What's my experience with pricing, setup cost, and licensing?
The cost of Microsoft Exchange Online is approximately $4 to $36 per user. They do not give a discount which is not good. The solution is expensive if you have 800 to 1,000 users. They should give discounts when you have a lot of users.
Which other solutions did I evaluate?
I evaluated Microsoft Exchange on-premise, and it has a lot of glitches and needs a lot of maintenance. I chose Microsoft Exchange Online to cut this risk on our day-to-day operations for organizational communication with clients. We decided to move forward with migrating most of our users from Microsoft Office 365 or Microsoft Exchange Online, where those critical users would be not in a risk position in case anything happened on the Microsoft Exchange on-premise.
What other advice do I have?
I chose to use Microsoft Exchange Online because of the disaster recovery, and clustering, and to make sure that our users are eligible for the business continuity process.
This solution is good if you have a critical business, you don't want to have any kind of down communication, you are located in multiple regions, your IT team is not large enough to maintain an Exchange on-premise servers or you don't have the large infrastructure to have clusters.
I rate Microsoft Exchange Online a nine out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Executive Vice President and Global Head of Research and Development at Bqube Global
Secure with good support and an easy implementation
Pros and Cons
- "It's not hard to set up."
- "We'd like to see more integration with other platforms."
What is our primary use case?
We are primarily using the solution for Office 365 and various other Microsoft products. It's used for any integration of any applications. Multiple company domains have been configured on a single exchange. It helps us standardize and consolidate connectivity.
What is most valuable?
We like the standardization we can get across all of our companies. We can put all domains on one exchange. The user can then have one single ID instead of creating five emails for one user.
It scales well.
Technical support is helpful.
It's not hard to set up.
The solution is stable.
The product offers good value for money. After a few years, we have seen an ROI.
What needs improvement?
There are no features that are missing.
We'd like to see more integration with other platforms. We'd like to explore the feature of SSO and Artemis.
For how long have I used the solution?
I've used the solution for more than three years.
What do I think about the stability of the solution?
The solution is stable and reliable. There are no bugs or glitches. It's very stable.
What do I think about the scalability of the solution?
The solution can scale well. It's cloud-based, which makes it very simple. We just have to approach our reseller and add on more licenses. You can have 50 users or 50,000 users, and it will work just as well.
We have about 1,000 or more users on the product currently. We do have plans to increase it to 1,500 by the end of the year.
How are customer service and support?
We may have used technical support previously and were able to resolve any issues within a week. They are very good. They are helpful.
Which solution did I use previously and why did I switch?
I did not previously use a different solution. Past colleagues may have used something else.
How was the initial setup?
The initial setup takes two to four weeks. It's pretty straightforward. We take each domain and consolidate everything on the exchange. We can migrate everything in one go, and usually, we migrate each company each week and migrate one by one, so that end users are not disturbed.
What was our ROI?
We have experienced an ROI after three to four years.
What's my experience with pricing, setup cost, and licensing?
We pay for the solution annually. The price is a bit expensive. However, it offers good value for money. The implementation cost is minimal. Also, now it is on the cloud, we don't have to worry about storage, maintenance, or hardware. The cloud is highly secure, and it helps save us money in the long run.
What other advice do I have?
This is the latest version. We are using the cloud version, and it is constantly updated. We are using all of the standard features that come with the cloud-based product.
This is a very user-friendly enterprise solution. Everything is very secure according to GDPR needs. The product is scalable, and its offering good value for money. Everyone can use it. It's a great product.
I'd rate the solution nine out of ten.
Which deployment model are you using for this solution?

Easy to use, and straightforward deployment, but is not stable
Pros and Cons
- "The solution is scalable."
- "The stability of the solution has room for improvement."
What is our primary use case?
The primary use case of the solution is for email and SharePoint.
How has it helped my organization?
We are beginning to explore Office 365 Online Exchange and Azure, which are part of Microsoft 365. We intend to create our Active Directory and Domain Controller on Azure and integrate OnTime Active Directory with Azure Active Directory.
What is most valuable?
I haven't encountered any downtime with Exchange Online so far. Last week, the entire Azure portal experienced an outage, which caused some disruption, but thankfully, we haven't had any issues with 365 yet.
What needs improvement?
The stability of the solution has room for improvement.
For how long have I used the solution?
I have been using the solution for over four years.
What do I think about the stability of the solution?
I give the stability a seven out of ten.
What do I think about the scalability of the solution?
The solution is scalable.
We have thousands of people using Microsoft Exchange Online.
How are customer service and support?
We have a limited amount of time to contact tech support, but we usually communicate with the vendor. If I have an issue, our Microsoft partner can help us with problem-solving.
Which solution did I use previously and why did I switch?
We previously used Google G Suite before switching to Microsoft Exchange Online.
How was the initial setup?
The initial setup is straightforward.
What about the implementation team?
The implementation was completed in-house with the help of our Microsoft partner.
What was our ROI?
We have seen a return on investment since we are taking advantage of the license and Microsoft Exchange Online's useful features.
What's my experience with pricing, setup cost, and licensing?
The cost of our annual license for the solution is moderate. I would give the cost a five out of ten.
What other advice do I have?
I give the solution a seven out of ten. Microsoft Azure has experienced outages at times, but it can be comparable to Amazon Web Services (AWS).
I strongly suggest using Microsoft Office Exchange due to its ease of use and maintenance, as well as its increased reliability and added security features.
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

A stable solution with a good storage capacity
Pros and Cons
- "It has helped us because we don't have to worry about servers crashing."
- "The mail-blocking feature is not great and could be improved."
What is our primary use case?
Our primary use case for the solution is focused on the email team. We are currently in a hybrid environment and have some users on cloud and some on-premises. So we are migrating everybody from on-premises to the cloud by the end of this year.
How has it helped my organization?
It has helped us because we don't have to worry about servers crashing. Everything has been stable since we began migrating to the cloud.
What is most valuable?
We have found the availability of large storage valuable.
What needs improvement?
The mail-blocking feature is not great and could be improved.
For how long have I used the solution?
We have been using the solution for approximately three years and are currently using Microsoft Exchange 2013.
What do I think about the stability of the solution?
The solution is stable, and we have not had any downtime in the last three years.

We rate customer service and support an eight out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We have not previously used other solutions.
How was the initial setup?
I cannot comment on the initial setup as a third party did it for us.
What about the implementation team?
We implemented it via a Microsoft third-party vendor.
What was our ROI?
We have seen a return on investment.
What's my experience with pricing, setup cost, and licensing?
The licensing cost varies. For example, we have E1 and E3 licenses. Currently, it's approximately E3 $20 per user.
What other advice do I have?
I rate the solution a nine out of ten. The solution is good, but the mail-blocking feature can be improved. I advise new users considering implementing the solution to consider using a third-party vendor for the implementation process.

Reasonably priced, reliable, easy to install, and helpful technical support
Pros and Cons
- "When you used to write to someone, you would often begin typing their name and their email address would appear; you would simply click and you would have the correct email address. That has been working for a while, but having the location address appear was a pleasant surprise. It was amazing."
- "I couldn't delete an email account because it was identified as my primary account by the application."
What is our primary use case?
I use Microsoft Exchange Online for email.
What is most valuable?
I was talking to my dentist this morning, and I was manually entering the appointment into my calendar, and I was impressed that Exchange would actually give me the address.
It wasn't always this way, but now it's all connected in some way. I just entered the name without checking to make sure I didn't have a typo, and my calendar was able to give me the address, it just popped up.
When you used to write to someone, you would often begin typing their name and their email address would appear; you would simply click and you would have the correct email address. That has been working for a while, but having the location address appear was a pleasant surprise. It was amazing.
What needs improvement?
I have been having problems with Exchange. Sometimes there are issues with emails, most likely from a POP3 server, and some of the email accounts, I am not sure which one, but emails stop coming in at some point if I don't update.
Not all of my email accounts are affected, but I have a few, and I am wondering if it is not my Gmail account on Exchange. There will be an upgrade at some point, and if I put it off, emails will stop coming in. That is a problem I have seen before, but then you do the upgrade, restart or restart the application, and usually, when you do the upgrade the problem is gone, and the emails are coming in.
Sometimes they change the interface. This has happened recently, and I'm not sure if it was something I did or something else. They don't ask for your opinion when they do this, and I am not a child anymore, and I despise it when they change the interface without consulting me.
I am sure they had good reasons for the last interface change, but now you have the mail calendar people and tasks on a very narrow vertical bar on the left-hand side of the screen when Exchange is open full screen, and it used to be on the left side of the screen, but near the bottom, and I used to select them there, but for some reason, it has changed.
Aside from that, it's a good product. I recently added a new email account. I now have four email accounts attached to my main computer from which I receive emails on a regular basis, which is beneficial. I was able to add email accounts on my own.
I had an issue with a delayed email account at some point. That was a long time ago, and I am not sure if the problem is still present; it could have been two or three years ago.
I couldn't delete an email account because it was identified as my primary account by the application.
I am not sure why any of my accounts should be considered my primary account if I haven't explicitly told the app that they are. I was unsuccessful in removing it.
I needed to figure out how to change which of my accounts was the main account so that I could delete the one that the machine thought was my main account. But that was three years ago, so I'm not sure if it's still that way, but I was irritated at the time because I wasted half a day figuring out how to do this.
How are customer service and support?
I contacted technical support and was surprised that Microsoft contacted me.
I had some account, login account issues on my Xbox One, and I remember being able to talk to someone in Microsoft, which was also amazing.
Which solution did I use previously and why did I switch?
I used Google Hangouts briefly, but I have been using Microsoft Teams for conferencing.
I am not well versed in Google Hangouts. I have issues when it is not Teams, which is why I use it all of the time.
When it's not Teams, I sometimes have issues with the desktop that I am using, and the microphone and speakers are not always properly configured.
I have a camera with an integrated microphone attached to my desktop, as well as speakers connected to the desktop, and there is occasionally an incorrect selection in the inputs for the microphone.
I am not sure if this is a problem with Google Hangout, Zoom, or something else. I know that Teams always works and that my computer always knows which option is the correct one.
At the start of COVID, when I started using these applications more, like everyone else. I recall attending a meeting where my camera was turned on but I was completely silent because I couldn't figure out how to make my microphone or select the input, and the meeting had already begun, my colleagues took over and I was there, people could see my face, but I couldn't speak.
Now that I've gotten a lot better at this, if the audio doesn't work within the first few minutes of the meeting, I can usually fix it by going into settings and selecting, trying every input until I can actually test and see that, the microphone is now picking up my voice.
Microsft Teams works great for finding the microphone on my machine, or the microphone associated with my camera, but not so well for other applications.
In addition to Microsoft Exchange Online, we use Microsoft Word, Microsoft Excel Teams, and sometimes PowerPoint.
How was the initial setup?
The installation was all done online. I subscribed, received a link, and installed the application. It is not an online version, but it is online in a browser.
As it was not installed with a disc, I consider it online. I subscribed to Office 365 or 360, and then I received links to install all of the available applications. They are on my machine, but they were not purchased at a computer store.
What's my experience with pricing, setup cost, and licensing?
We have an Office 360 subscription.
I'm not sure. It's somewhere between $100 and $200, but I couldn't tell you.
I didn't install it on my computer. The app is a resident on my computer, but it's a Microsoft Office subscription with automatic updates, and it's not like a version of the application that I purchased and installed on a disc on my machine.
I don't own the application because I pay an annual subscription to use it.
Previously you had to buy it at a computer store and own it until you purchased the next version. That is not the case. I pay approximately $120 or $150 per year, and as long as I pay that amount, they will do regular updates so that I always have the most recent and greatest version of the application.
What other advice do I have?
It's a good product, I would rate Microsoft Exchange Online an eight out of ten.
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

My company requires people with some IT knowledge to handle the product's deployment and maintenance processes.
What about the implementation team?

Which other solutions did I evaluate?
My company chose Microsoft Exchange Online over other products since we have a partnership with Microsoft. For our company's business uses, Microsoft helps save costs and offers good support.
What other advice do I have?
The feature of Microsoft Exchange Online I found to be the most beneficial for team collaboration stems from the integration capabilities. Microsoft Exchange Online can integrate with products like Microsoft Teams or Windows Live.
I have seen that Microsoft Exchange Online's dashboard ensures the aggregation of all the integrated items in a single interface. I think my company has to order Microsoft Teams and apply for it separately to be used on a product like Microsoft Exchange Online.
The security and compliance features of Microsoft Exchange Online have impacted our company's business operations as it is a good tool for business needs, and I haven't seen any major issues with it in any of the items provided. I have also not had any negative reviews or complaints about the product from our company's teams.
I use the solution's calendar functions for my scheduling needs. but I don't know how it offers any support.
The tool's integration capabilities were used for the benefit of the management of the areas attached to the solution from a single place.
I rate the overall tool a nine out of ten.

How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I previously worked with the IBM Domino mail system. Compared to the on-premises model of Microsoft Exchange Online, the IBM Domino mail system's maintenance and administration upgrades were less complicated.
How was the initial setup?
It wasn't difficult to migrate the solution from on-premises to the cloud. It took us around one week to migrate from on-premises to the cloud because we don't have that many mailboxes.
What's my experience with pricing, setup cost, and licensing?
We are Microsoft partners. We bought some licenses, and some are within our package or partnership with Microsoft.
What other advice do I have?
Earlier, we had the solution on-premises, and then we migrated to the cloud. The solution helped with the planning and time management within our organization by providing everything that Outlook offers to end users, including email and calendar.
The solution does not provide 100% security, and some emails are still detected as malicious by our other endpoint security solution. Microsoft Exchange Online does not require any maintenance from our side.
Overall, I rate the solution an eight out of ten.
