Is there away (without using the individual Rule setup) to redirect any mail (internal and external) sent to a GroupWise user to an external address.

Have several users who are being setup in a external exchange system and don't want to maintain 2 e-mail accounts.
Can the e-mail sent to the old GroupWise account be re-directed to the external address if a internal GroupWise user sends e-mail to the GroupWise account ?

If a user has the old GroupWise account in thier Frequent contacts or personal address book we want this forwarded.

Also how do you redirect a internet e-mail addressed to the GroupWise address to the external address ?
