Hi everyone,

We have a 801 front and back-end environment. A client of ours get an undeliverable email message with "User not on post office
Error = D101" when trying to send to a self "created contact" within a self "created Address Book" that is a nickname within our GroupWise system. If we create the contact from within the "Default Address Books" and send a message, it is delivered successful. If we type in the email address in the To: field of the message, this also deliver successfully. Have anyone ran into this issue and found a fix?

Thank you for your time and attention towards this issue in advance
