Microsoft Exchange Online is cloud-based and we always use the latest version.
I believe that my company has been using the solution for many years, although I cannot state for certain how many, as the company was doing so prior to me having joined.
We are currently using the online version of the solution, Office 365.
We use the solution in respect of Office 365, email, Office, OneDrive, SharePoint and Teams.
The licensing price of the solution could be lower.
The solution is scalable.
The technical support is decent.
We did not make use of other solutions prior to Microsoft Exchange Online.
As the solution is cloud-based, we found the installation to be easy. I do not know how long it took, as I was not responsible for this.
Deployment and maintenance involved two people.
The licensing price could be lower. The subscription fee is monthly.
Our organization has 300 users making use of the solution.
