I’ve been getting a lot of questions around which Mobile features work with the different versions of Exchange currently available in the Market – Exchange 2003, Exchange 2007 and Exchange 2007 SP1.  Since each is a drastic improvement from its predecessor they all have different features, and I thought I’d compile some of these feature sets into a basic matrix.

Additional information on the Matrix below at can be found on Technet and the Exchange Team's Blog.

For the Matrix below:
E2K3 SP2 - Exchange 2003 Service Pack 2
E2K7 - Exchange 2007
E2K7 SP1 SCAL - Exchange 2007 Service Pack 1 with Standard Client Access Licence
E2K7 SP1 ECAL - Exchange 2007 Service Pack 1 with Enterprise Client Access Licence

While the table above doesn't cover every feature available for every version of Windows Mobile (there are additional features such as Setting OOF, forwarding Calendar appointments etc)  it does focus on all the policy options available in the Exchange Administration Console.

This matrix was compiled with information found at the following locations:
