Pros and Cons
- "Intuitive and easy to use."

- "I feel that there is a need for improvement in the product, considering that there are some concerns with the tool's integration capabilities."
What is our primary use case?

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.

Used for emails and provides integration with other services for shared calendars
Pros and Cons
- "The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars."
- "The solution’s technical support could be improved."
What is our primary use case?
We use Microsoft Exchange Online for emails.
What is most valuable?
The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars.
What needs improvement?
The solution’s technical support could be improved.
For how long have I used the solution?
I have been using Microsoft Exchange Online for two to three years.

I rate the solution’s technical support a six or seven 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.

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?

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.

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.

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?

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.

What's my experience with pricing, setup cost, and licensing?
