If you send a message, the following error message may be displayed:
The message interface has returned an unknown error. If the problem persists, restart Outlook.
CAUSE
The message that you tried to send is addressed to a user or personal distribution list that does not reside in your personal address book or does not reside in the global address list.
This may happen if you log on to a mailbox and try to send a message that was previously addressed by using a personal address book for that mailbox.
RESOLUTION
The user who created the original message must send that message from the computer where the personal address book that contains the personal distribution list is stored.
