Hi

I followed the link on this site to forward someones mail - it works well but every message sent comes back with 5.1.1 mailbox user@mydomain.com.au does not exist but the user gets the mail on both the exchange server and the forwarded mail (Gmail)

Any ideas how to overcome this?
Interesting point - it seems to drop the au off the message - the address is mydomain.com.au but when the message comes back it says .com Hmmmmmm?

When creating the forwarded email, did you create a contact in Active Directory Users and Computers, then forward the email on to the contact?
Assuming that this is the case, as this is the standard way to do it, check the email address in the contact is the address you are expecting to see.
5.1.1 means that there is no recipient by that name at the organisation that you are sending to, but if the mail being forwarded is received externally, this is rather odd!
Have you checked the recipient domain in DNS? - you can use a site like www.dnsstuff.com to check.

If the user@mydomain.com.au is part of the internal exchange organisation then there should be no need to create an external contact?
Is your internal domain .com?

Can you provide some details as to how the forwarding is configured?

My appologies for the delay - it seems that loading sp2 for Exchange has solved the problem.
