I am unable to remove a "Mail Delivery Error" in Outlook
98. The Error reads as follows" "The message could not be
send because one of the recipients was rejected by the
server. Server Response "501 need user@domain at
<Undisclosed-Recipient:;>',(Account:'postoffice.worldnet',
SMTP Server:'mailhost.worldnet.att.net',Error Number:
0x800ccc79).

Has anyone seen this before? How did you get rid of the
Error message??
