Enterprise Vault slows down Outlook 2010
We are using Outlook 2010 with Exchange 2007 SP3 and experience the following problem:
Switching to other mailboxes is very slow. Opening the users primary mailbox is normally, but switching to another (shared) mailbox can be very slow. Sometimes it takes for more than 20 seconds before the folder is opened. I must say that the mailbox is 6,7 Gb large, with 106.000 items, but is was no problem with Outlook 2003.
We do not want to use the Outlook Caching feature as we are using Vmware View.
After troubleshooting with Microsoft we discovered that disabling the Enterprise Vault Plugin (EV HTTP client 9.0.1) eliminates the problem.
Is this a known issue ?
First thing i would suggest is try the newest cumulative client hotfix

See if that helps at all, and if not try opening a case with Symantec, i can see what it's doing but no explanation as to why since i don't have access to source code any more :)
