When I email someone from the office using outlook 2003 and Exchange 2003 I get an mail rejection:
"The following recipient(s) could not be reached: on 18/07/2008 15:54
The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address."

Yet when I email the same address from Hotmail it works, message gets through.  Sent email 8 times with 8 rejections.

Restarted all exchange services, rebooted broadband router, and did an NSLOOKUP to verify we were talking to the recipient mail server IP address.

Does anyone have any idea how email from Hotmail gets through when this looks like a problem at the recipient mail server.  Is Exchange case sensitive or something?  Recipient mail server is also Exchange.

Email is from a director so it's important it gets through.

Thanks, Peter.
