illegal alias

[Guest]

Hi,

I experience a stange issue, the user (e-mail address removed) tried to send an
email to (e-mail address removed) and he received this error message:
"The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was '(e-mail address removed)'. Subject 'Test',
Account: 'tata', Server: 'smtp.example.com', Protocol: SMTP, Server Response:
'550 5.1.1 unknown or illegal alias '(e-mail address removed)', Port: 25, Secure(SSL): No,
Server Error: 550, Error Number: 0x800CCC79.

But tata can send an email to another user (e-mail address removed) (titi is in the same
server as toto).
(e-mail address removed) and (e-mail address removed) are different accounts and both of them exist in
the same server.


Have you any idea what is wrong?

Thanks,

Haydar

if the server is rejecting it, it's a server problem, not outlook.
