Well, did the client install on our Exchange 2007 server (all roles on one box with FSE). Windows 2003 R2, etc. This box only has Exchange installed.
I used SEPM to push the x64 client based on all the confidence this thread seemed to exude.... I assumed that SEP would detect Exchange and configure accordingly.
You guys must have been lucky, or I am a moron..... 'cause SEP was all but blind to our Exchange, as far as I can tell. No exceptions, no registry entry labeled "exchange exceptions" as suggested above, etc. I used a separate group with it's own policies and installed only AV/AS, nothing else.
If you read MS's Technet article on file level scanners and Exchange 2007, it is pretty scary what they want you to exclude. There is a pretty good Symantec article on SAV 10 and Exchange 2007, so why isn't there one for SEP 11????
JFTR, if folks are assuming SEP is always Exchange aware, they may be in for a rude awakening as their stores get corrupted!
