Hello. we have had a server running W2K8 with exchange 2007 installed on it. we have recently increased the number of exchange licenses. These licenses were added to the existing exchange server standard CAL license, but i do not understand how to increase this number on the exchange server. all examples i find show how to add a license key to a unlicensed server.

Hi, Exchange 2007 has two edition, Standard Edition and Enterprise Edition. You can mix and match the server editions with the CAL editions. For example, you can use Enterprise Edition CALs against Standard Edition. Similarly, you can use Standard Edition CALs against Enterprise Edition. The Enterprise Edition CAL is an additive CAL, which means that you buy the Standard Edition CAL, and then add an Enterprise Edition CAL on top of it. An Enterprise Edition CAL provides you with the features listed in the last column of the Exchange 2007 CAL Offerings table. Note that some of the listed features can only be purchased through a volume license program, and they are not available as retail purchases.
