Going from Groupwise 2014 to Exchange 2013 (what a downgrade, huh?), I would like Groupwise not to be authoritative for our domain anymore. That is if someone sends a mail from their GroupWise client, mails should not be delivered to the appropriate Groupwise server recipient, but be relayed to our Exchange server instead.

It is probably very simple when you know where to click - or which command to shoot. Anyone can share how-to?

Regards, Lars.
