Have an Exchange 2000 server running in a Win2K AD environment - employee left 2 days ago so my supervisor changed the administrator password - now...we cannot receive any external email - I do not know if they are related - here is a bounce message:
Your message cannot be delivered to the following recipients:
Recipient address: email@example.com
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550 Requested action not taken: mailbox unavailable
Remote system: dns;mail.skycapitalholdings.com (TCP|18.104.22.168|42772|22.214.171.124|25) (SMTP service ready)
I am not an Exchange admin - that was the guy who left - any idea how to fix this?
