I have Exchange Enterprise CAL w/o service 75and Exchange Server Standard CAL 75How do I determine if my Exchange server is Enterprise or Standard?Thanks for helping the newbee.

Hey,You can use Get-ExchangeServer cmdlet to retrieve server edition in EMS.Get-ExchangeServer | FT Name, Editionhttp://technet.microsoft.com/en-us/library/bb123873.aspxOr you can see the properties of Exchange Server in EMC.Server Properties > General Tabhttp://technet.microsoft.com/en-us/library/bb125221.aspxHowever CAL license and Server license are different.
