I just setup my Exchange 2000 server at home through cable modem.
Ironically, I am able to send and receive the email through internal and
external on Outlook2000. However, Express is having a problem to send the
message with the following error code even with internal client:
The message could not be sent because one of the recipients was rejected by
test', Account: 'mail.domain.com', Server: 'mail.domain.com', Protocol:
Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
The closest answer I can find from technet is
Unfortunately, it did not help me out. The thing puzzles me why Outlook
works except Outlook Express. I understand Express is using pop3 to
retrieve the data but both of them are using SMTP to send the memo out.
Any help will be appreciated.
