Hi everybody, actually I have migrated from Exchange 2003 to Exchange 2007 over Windows 2008 R2, and the users that access to OWA used to access through the URL https://mail.our_domain_name.com/exchange and we have a problem because the current URL for OWA in Exchange 2007 is https://mail.our_domain_name.com/owa to fix this we have redirected into IIS7.0 in the CAS server the /exchange virtual directory to point to https://mail.our_domain_name.com/owa, but when the users type the https://mail.our_domain_name.com/exchange URL and the press enter, the browser´s addres bar changes to this another url: https://mail.our_domain_name.com/exchweb/bin/auth/owalogon.asp?url=https://mail.our_domain_name.com/exchange&reason=0&replaceCurrent=1 and we get the form of authentication of OWA, when we type the credentials in that form we get the next error: 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. And the URL in the address bar of the browser turns on https://mail.ositran.gob.pe/owa/exchange. I'd like somebody can help me to redirect the https://mail.our_domain_name.com/exchange URL to the https://mail.our_domain_name.com/owa transparently. To force the users to use the https://mail.our_domain_name.com/owa is not an optión because of the https://mail.our_domain_name.com/exchange URL is embeded in a bunch of applications that works with OWA. Thanks in advance for your help Have a good day Felxs.Felx

Hi Is this a single server setup? Is every user moved to 2007? Start with removing all redirections, get it to work without having any redirection. That can be easily changed afterward, just do it this way to avoid any unnecessary issuesJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
