Exchange 2011 - mail bouncing back from from one user sending scans via address book on Fuji Xerox

[SWC6284]

A user is sending e-mails on the Copier scanner to an internal e-mail address and they are bouncing back with the following error.
all other users can send to their addresses no problem. Just seems to be this particular mail box. I tried adding an Alias address, but still get the same error.

Anyone got any ideas? Seems to be something in there Exchange server.
Really appreciate the help!
