Hi Jim Yes, you would need a trust relationship between the domains, would it not be simpler to let them use OWA to access the mailbox rather than establishing trusts, they can do most things with OWA.

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 ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: mark@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
