Q: (from John)
We are looking into Exchange 2010 and would like to get a list of all the differences between Enterprise and Standard versions. Also, we need to know is some of the Enterprise features such as Integrated Archiving, Multi-mailbox search and legal hold, and advanced journaling are available with the Standard version, if you use an Enterprise CAL?
We are looking for more info on how the standard and enterprise CALs interact with BOTH standard and enterprise Exchange Server, and what features are available depending on which CAL you have.
We are having trouble determining which CAL and Server version to buy depending on what features we need for a certain customer, is there a breakdown for this somewhere?
the functionality of the client is dependent on the CAL and independent of the Server.
The Exchange Licensing page is a good reference:
So, to take the specific features the customer mentioned:
Those features are all defined by the CAL(s) selected and independent of the Server choice. I view the CAL as the choice of features and the Server and the choice or scalability.
