I am having this exact same problem, but, it's sporadic. If I step away from
my desk and a "message storm" occurs I could have 1000s of e-mails when I get
back. It doesn't happen with every e-mail just certain ones and there
appears to be no pattern as to who is sending them.
We are all using MS Office Outlook 2007 (12.0.6316.5000) SP1 MSO
(12.0.6320.5000) and we connect through our enterprise network to the same
cluster of exchange servers.
