Well, for simplicity sake, set the delivery point to Mailbox - XXX. Then open Outlook (or excange client) on the server and let it remap your folders and inbox. This doesn't buy you anything as far as reliability is concerned, however, it should solve your issue.

If you WANT to use personal folders, let me know and I'll try to respond when I have more time. Using personal folders will allow your SQL Server to cue up e-mails in your outbox when the exchange server is unavailiable, and send them when exchange comes back on-line.
