Archive emails to a locked archive for a Shared Mailbox.
Is it possible to archive old emails to a locked archive for a Shared Mailbox (so that messages are retained and stored, but not accessible to every user)? I'd like to apply this to a number of Shared Mailboxes that are accessed widely. I'd like to archive all messages over 3 months old so that standard users of the mailbox can only see the latest 3 months emails (but all emails are available to admin users in the archive). Possible or pipe dream?
