The most valuable features of the solution are the security of the email flow, the primary security, having a dedicated, consultative space where if I send an email from a billing app or from a browser or anywhere, it gets stored in consultative space, and some of the end users features such as Word solution.

The solution
The solution doesn't require any maintenance. The solution is a cloud platform and everything is taken care of by Microsoft, so there is no maintenance required. It's maintenance-free.
I recommend the solution. As soon as you know what your needs are, you can go ahead with Microsoft Exchange Online. You don't need any demonstration of features, and you don't need to do any POCs.
I think the solution is pretty reasonable in what it does. In terms of mobile applications, that is Microsoft Outlook for Android and iOS integration, which can make some integration to Microsoft Teams application, which is already prospected in the desktop application. If they can have it in mobile application also, that would be good. But as a solution, I couldn't think of any new features that are required presently.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

What is most valuable?

Project Manager at a tech vendor with 10,001+ employees
Great for collaboration and syncing calendars with good reliability
Pros and Cons
- "The solution has been stable with good performance on offer."
- "The solution could be a bit cheaper."
What is our primary use case?
We use Microsoft Exchange for sending emails and running calendars. With the calendars, we are able to check other people's calendars and be sure of their availability so that they can deploy solutions. That's what we normally use it for.
What is most valuable?
The solution is great for collaboration purposes.
The calendar capabilities are great.
The solution has been stable with good performance on offer.
The product can scale.
What needs improvement?
The solution could be a bit cheaper.
I'd like it to be more voice-activated and to have more AI so that it becomes easier to use. The world is moving toward more AI and machine learning, and likely they will adopt more of it in the future.
For how long have I used the solution?
We just migrated to the solution. We've used it maybe for about a year and a half so far.
What do I think about the stability of the solution?
The solution is very stable and reliable. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
I've not had any problem with it personally in terms of scaling. Due to the fact that it's connected, it pulls everything down. I'm able to do whatever is needed of me with it without stress.
Everybody is using it now in the company. If it was not scalable, I don't believe over 100,000 staff members could be using it without issues. It has to be scalable.
If we want to increase usage, we simply purchase more licenses.
How are customer service and support?
I've not had any contact with tech support. It's been very stable for me. There has been no need.
How was the initial setup?
I'm not part of the team that does the installation. That said, I know that Exchange should be good in terms of implementation. In the mailing lists that I used to install, the installation was straightforward. If you get your configurations right, it works. It works well without any trouble. This is Mircosoft. I'm sure it's fine to install.
What's my experience with pricing, setup cost, and licensing?
You do need to pay a licensing fee in order to access the solution. There are also enterprise agreements where companies would have to agree to a certain level of volume.
It could be less expensive. If it was, more companies would use it.
What other advice do I have?
I'm an end-user.
I would recommend the solution to others and rate it at a ten out of ten. It's in the Cloud; people don't need to have anything on-site or to worry themselves with problems any longer. Microsoft takes care of the back end while companies can focus on their day-to-day work and be more productive.
Which deployment model are you using for this solution?
Public Cloud

Excellent email solution with EOP filtering service
Pros and Cons
- "There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well."
- "I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default."
What is our primary use case?
I am an implementer of this solution. My clients use it as an email solution.
What is most valuable?
There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well.
What needs improvement?
I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default.
What do I think about the stability of the solution?
It's a stable solution.
How are customer service and support?
Microsoft always has nice support. You are able to create some tickets on the Microsoft support pop up, it's quite simple.
How was the initial setup?
On-premise setup for one server took about seven hours in total - I would expect this time to double, triple, etc. depending on the number of servers that you have.
I would expect cloud deployment to be significantly faster - maybe two hours for 100 email boxes.
What about the implementation team?
We used an in-house team of one senior engineer and one junior engineer.
What's my experience with pricing, setup cost, and licensing?
I think that the price is a little high, especially considering that Google have a similar, free email solution.
What other advice do I have?
If you are looking to deploy on-premise, make sure that you have a small data center, or even a small room for physical security. Otherwise, you should deploy Exchange online.
Which deployment model are you using for this solution?
On-premises
