What happens: users mailbox is archived locally for reduce mail box size. Other db's contains links to e-mail messages and are not longer available, because the message is gone from the mailbox to the archive.
Is there any way to indicate a fail-over when the message isn't found in the mailbox (at least for the local user) ?
No , I think there is not any way to indicate a fail-over when the message isn't found in the mailbox. Please correct me if I'm wrong.
