EMS – Exchange Server 2007 Product Keys

Exchange Server 2007 permits you to install the product and use it for 120 days in trial mode without entering a product key. If you intend to use your system in production you should enter your Exchange Server 2007 product key within that 120 day period (preferably before your system goes into production).

You can check the status of your servers using the Exchange Management Console.

[PS] C:\>Get-ExchangeServer | fl name,productkey,*trial*

To add your product key to a server use the Set-ExchangeServer cmdlet.

[PS] C:\>Set-ExchangeServer -Identity MAILSRV1
-ProductKey 12345-ABCDE-12345-ABCDE-12345 

WARNING: The product key has been validated and the
