My small business recently moved from Exchange to Yahoo for email. I interested in allowing users to still access the old Exchange emails through Outlook Web Access and allowing them to forward any emails they wish to the new Yahoo account. They can access Exchange fine through OWA but when they forward an email it is processed and shows up at OWA instead of at Yahoo. What do I need to change at the server so Exchange can still process outgoing email but would sends them to the new Yahoo accounts?
The domain name has not changed.
