How to check the current version of your Exchange Server?

Just like myself, I forget where to look to check my Exchange Server version. This is a simple guide to remind me, and I hope other administrators will help them too.

Open your Exchange System Manager, go to Administrative Groups, First Administrative Group, then Servers. The list of servers will appear in the right box, in here you will see the edition, server version, and last modified date.

Cheers.
