Can't use Virtual Vault when also using GPOs to block PST files

[BryanC]

Hi,

I'm testing methods of blocking users from creating PST files in Outlook 2007 and 2003.

I've noticed that once PST use is prevented on 07 or 03, the Virtual Vault feature can not be used.

We have tested several delivery methods, the end result is a registry key "disablepst=1" in the appropriate location in the registry.

Once that is achived, Pst use is prevented just fine but the Virtual Vault begins to fail.

Any ideas?

To configure users' computers

The setting must be of type REG_DWORD, and have a value of 1.
