When a user mailbox or folders on a file server are archived, the access permissions set on the original folders are also set on the associated folders in the archive. So users that had access to the original folders will also have access to the folders in the archive. This includes delegate access permissions in Outlook. For folder permissions to be set up on new archives, you need to synchronize folders and permissions.

Alternatively, you can share access to an archive either by modifying the archive's properties in the Administration Console, or using the New Archive wizard in the Administration Console to create an archive specifically for sharing. Archives created using the New Archive wizard do not contain a folder structure.
