Has anyone had numerous issues with TSM TDP for Exchange 2010. We continue to 
struggle with VSS issues
and Microsoft claims its not their issue. We initially had Exchange circular 
logging enabled and have since
turned that off as recommended.  I see that  TSM TDP for Exchange 6.4  is 
available.

Configuration

TSM 6.3.1.15 server on Windows 2008 R2 Enterprise
TSM 6.3.1 BA client  on Exchange servers
TSM TDP Exchange 6.3.1
Exchange 2010 Version 14.02.0247.005
Exchange Windows servers 2008 R2 Enterprise SP1
