Have a look if the person you sent it to has set permissions and delegates
to this non-existent user name. I have seen this before.

Exchange 2003 SP2, Outlook 2003, When I schedule a particular user for an
appointment and hit send. I get a NDR:

The following recipient(s) could not be reached:

"Different User'S Name" on 12/13/2006 10:50 AM
The e-mail account does not exist at the organization this
message was sent to. Check the e-mail address, or contact the recipient
directly to find out the correct address.

However, the user's name in the NDR is different than the one I sent the
appointment to. In E-Mail Addresses- there is no X.500 e-mail address
listed. I checked X.400, and settings are correct.

Thank you,
BM
