Microsoft Exchange

Hi, recently changed mail/dns for a domain to use Microsoft Exchange. Now I need to setup a new email address but can’t unless I remove all the DNS info for Microsoft Exchange. Once Exchange is handling email, if I want to setup a new email address do I go through Exchange to do so?

Correct. The DreamHost Panel can only manage addresses which are hosted by DreamHost. If you’re using another service, such as Google Apps or Exchange, you will need to use their management interface.
