Exchange 2007 SP1 available for download

As announced yesterday in the TechNet flashes Exchange 2007 SP1 is now available for download here.

Of course I'm most interested in the Unified Messaging enhancements, but there many other interesting improvements as the import/export of PST files which is very interesting for our migration projects (And we also look forward to better stability of the product due to all the included fixes)
