Earlier days for the legacy versions of Exchange, there was no Shell Scripts and this was not implemented till Exchange server 2007 Release. So let’s see how to find out version Build numbers.

Ways to find out the Build numbers and Version.

STEP 1 :

Start the Microsoft Exchange Administrator program.

In the left pane, expand the objects until you locate the server object, and then click the server object.

On the File menu, click Properties.

For Exchange 2000 or Microsoft Exchange Server 2003 Server, then follow the below steps:

Start the Microsoft Exchange Administrator program.

In the left pane, expand the objects until you locate the server object.

Right-click the server object, and then click Properties.

 STEP 2 :

For Exchange 2007, 2010 or Microsoft Exchange Server 2013 Server

How can we find out what RU is currently installed?
