Greetings, I have both Exchange 2007 Mailbox and Hub roles installed on one server and the Client Access role installed on another. This is a 32 bit test environment using only Beta 2. It also has a fully functional Exchange 2003 implementation sending and receiving email correctly. So far, I have Outlook Anywhere and OWA working outside the network, but I can only send and receive mail to and from the internal domain. Mail from outside sources (Hotmail, Yahoo, etc) is never received. I've looked at the Receive Rules and created new ones, also there is no Permission Groups tab as there is in the production version. Does anyone have experience with this? Thanks Jeff
