Hi, My company has over 200 (mail) domain names. Without polluting the users Active Directory policy addresses, how can I strip the (accepted) domain name and replace it with the authoritive domain name? For instance, the authoritive domain name is 'auth.com' and a message comes in with the TO field addressed to the accepted domain name 'James.Bond@accepted001.com', or 'James.Bond@accepted200.com'. Question 1: How can I re-route this message to the mailbox that has only one mail address equal to the authoritive domain James.Bond@auth.com ? This issue results from a groupwise to exchange migration, the groupwise environment just accepts the mail, and in case the recipient does not exist it will replace the accepted domain with the authoritive all by itself. In my opinion this can be realized by Exchange 2010 also, but only if every user has all the accepted domains as well as the authoritive defined as a policy address in AD. Question 2: Is this Correct? Gr, Mike Schmeitz

hi, What's your exchange version? >>>How can I re-route this message to the mailbox that has only one mail address equal to the authoritive domain James.Bond@auth.com ? I don't think you can. Why not consider to use transport rule to forward message to the mailbox, or directly set the forward on these mailbox. If you have mutiple address, you can use all addresses to receive mail, but you only can use primary one to send. >>>Without polluting the users Active Directory policy addresses You can use the email address policy to distribution the address.

Hi, Thought about transport rules also, but they are too limited. Solution is to use address rewrite. This requires an Edge server, can't be done in Office365 nor on HUB role :-( Thnx for your effort! Gr, Mike

Ed, Came to the same conclusion, which means we require an EDGE server since Office365 can not handle it, not can a HUB. Thnx for your effort! Gr, Mike
