With EVPM, sometimes it's the simple things

I have to admit I do spend a long time battling with EVPM between different versions of Enterprise Vault, and different versions of Exchange. It can be a pain.  But it is also pretty powerful, and useful for many different tasks.  Sometimes though, it's the simple things.. as I spotted on the Symantec forums a little while ago.

The issue was that EVPM was erroring with:

65 10:20:17.015  [8408] (EVPM) <7184> EV:M CMAPISession::GetExchangeServerDnFromSession - calculate ExchangeServerDn

76 10:20:17.171  [8408] (EVPM) <7184> EV:M ~EVPM - Successfully processed 0 out of 0 mailboxes

The error: 'Error creating privileged MAPI session'.

Annoying.

But the fix is cunningly simple, as shown in the technote.

It's just a matter of removing the cached mode switch on the Outlook profile on the machine! Okay, not quite so super simple..  it's often pushing by a group policy so the thing that has to be changed is that:

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Cached Mode

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\Cached Mode

1 = Enabled

0 = Disabled

Hope that helps someone!
