Optional. Lets you reset the permissions on archive folders to the user's default permissions.

When it migrates the contents of a PST file to an archive, Enterprise Vault assigns the same access permissions to the imported PST folders as it does to their parent folder. The access permissions on the PST file itself are not transferred to the newly-created folders. This is in line with standard Exchange policy, but it may give rise to a possible security issue: Using facilities such as Archive Explorer, any user who has read permissions to the parent folder in the Exchange mailbox can access the migrated items in the PST import folders. You can address this issue by resetting the permissions on the archive folders and thereby stopping unqualified users from viewing the contents of PST import folders.
