There are no intrinsic permissions that you can set in Outlook to provide that capability in a mailbox or .pst file, since a user has full access to all their own folders. Any "permissions" would be restrictions imposed by the operation of such a tool, e.g. deleting new items the user puts in a particular folder or rolling back the user's changes. (Note that the Outlook model itself provides no way to prevent the user from deleting items. I'm not conversant in Extended MAPI's capabilities in that area.)

The obvious (theoretical) alternative is to use Extended MAPI to create your own custom information store.

Aha, and if I use such a tool, it will set permissions specifically for
outlook-like tools or globally with MAPI? Or i can't set that dirty
permissions for ALL mapi clients at all?
What u said is my goal - i mean creating that "3-rd party tool with its
own security mecanism", so i need to know if it will be able to set
permissions
"once and forever" ))))
