Did the sync work? It appears that it did not but it very well could be because I don't understand its functionality.
The administrator guide states: Controls whether synchronization of delegate and shared folder
permissions within mailboxes are synchronized. If these are not synchronized, only mailbox owners have access to the corresponding archives. For example, this prevents delegates, from having access to mailbox archives.
I have turned this value to ON and then I ran a synchronization on a specific shared mailbox. The synchronization task included:
Archiving Settings
Mailbox properties and permissions
Folder hierarchy and permissions
At the top of the information store for this particular mailbox, there are a couple of distribution groups with permissions assigned: Owner and Reviewer. Permissions to a Vault can have three values:
Read
Write
Delete
Perhaps I am over-analyzing this, but I would assume that an information store permission value of "Owner" would inherit all three Vault permissions. "Reviewer" permission would inherit the "Read" Vault permission.
If this isn't the case, I will resort to EVPM for issuing permissions. Thanks again.
