Hi Mike, Yes, we set something like that up a couple weeks ago. You need to include those domains in the recipient policy and create addition UPNs in the Active Directory Domains and Trusts console. Then the users can log on using their domain account (SMTP domain, not Active Directory domain).

Has anyone else done this successfully? I have already read resources like these ones: http://archive.devx.com/premier/mgznarch/exchange/2000/08aug00/ds2_0008/ ds2_0008.asp http://www.msexchange.org/tutorials/Shared_Hosting_Exchange_2003_Part1.h tml Any other resources? best regards Mike Salim. ------------------------------------------------------ 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 ------------------------------------------------------
