Outlook 2000 on Windows 2000 pro (sp2), Exchange 2000 (sp1), Window 2000
I have a problem when sending mail to a select few domains for just a couple
of users out of approx 40 users.
An email can be sent to UserA from a domain (eg uk.royalsun.com) and
received by UserA. UserA replies, but the exchange server gives the error
"Your mail system could not find a way to successfully communicate with the
However, userB on a different workstation can send mail to that domain
without a problem - using Outlook connected to the same exchange server (we
have only the one).
UserA has tried logging on to a different workstation but still Exchange
server returns the error message.
I have run exhaustive tests and always UserA cannot send mail to *some*
domains whereas all other users can.
Has anyone experienced anything similar?
