ok, just a quick question hopefully..lol, Installing a 2010 exchange server into a domain that already has a 2007 exchange server that has nothing to do with the users that will be using the 2010. They have 2 of their own accepted domains. The new server will have its own. After installing 2010 i noticed that it went out and linked itself to the 2007 exchange server and pulled in all the mailboxes from that other server. I haven't added any mailboxes for the new users yet. Should i just leave those there or remove them. Is there a way i could filter them from the address policy so they won't get the 2010 policies?
