I made a new 2012 Post Office.
Unfortunately the new address for my client is like this:
I cannot seem to restore the old mail from a local backup to the new
server. So I wanted to just leave people running on the old caching mailbox.
However the difference in naming schemes means that it will not log in.
Can I change the email address at the caching mailbox level?
Any thoughts why a local backup will not restore? It should be original
mailbox name independent...
