Hi all, am scrapping the idea of IMAP I floated before but was hoping to get clarification on one point. 1. If domaina has 250 users distributed over 10 sites and using Exchange with no relative problems via a VPN but at the 11th site users belong to a different AD domain named domain b, can I have the users at domain b access Exchange mailboxes at domain a without a trust relationship. 2. I configured an Outlook account at a pc in domain b to open a mailbox in an Exchange server in domain a. It resolved via DNS and checked the name properly but the Outlook client only open with a set of Personal Folders I have configured on pc in domain b. 3. Both the PDC in domain a and b can see each other via a VPN connection over the Internet with routing helping. 4. Do I need to set up each domain to trust each other in just have domain a trust domain b to let it use the exchange mailboxes? Thank You and I need help on this one Jim
