Exchange - Mail-enabled user does not exist

Hi I have an exchange/SBS2003 and a number of mailbox enabled users with email addresses xxx@mydomain.com.

I have tried to add a person who never connects to the Domain, as mail-enabled user so that he can collect email using the address @mydomain.com but via his own ISP.

I believe I have setup the mail-enabled account correctly within exchange but when an email is sent to him the sender gets a message saying:-

john@mydomain.com
550 5.1.1 User unknown (in reply to RCPT TO command)

Can anyone advise me what I am doing wrong...Thanks

I  doubt that will work... do you have an rpc over http or an owa solution in place??  I cannot see how a use can pick up company emails remotley without the above apart from having to VPN in.  He cannot just download his emails without any of the above solutions

Hi.

I was trying to get this scenario to work as per a previous question because it looked fairly
simple  (exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_22730967.html?)

I work with exchange infrequently and would prefer not to use rpc over http or an owa solution as they seem complicated and I might end up getting totally confused. Thanks...

Ok simple.

that solution says instead of giving him a mailbox, create a mail enabled contact with an SMTP address this will re-direct his email to an alternative mailbox (ISP mailbox, yahoo, gmail what ever).  This way he will log on to mailbox and recieve all his company emails....

I would also consider facts like virus protection for him.... and if security is an issue then encrypted emails could be considered??
