I have installed Exchange 2007 SP1 as a CAS role on Server 2008. I have migrated my mailbox over to our 2007 mesaging envrionment. When I access OWA I am able to log in using the /OWA virtual directory but I cannot log in using the /exchange virtual directory. When I attempt to log in using the forms based authentication, it just displays a line "The user name or password that you entered is not valid. Try entering it again." Users with a 2003 mailbox are able to log in with no problems using the /exchange. I do not know where the problem could be here. I have uninstalled and reinstalled IIS and exchange as described in this article. http://support.microsoft.com/kb/320202
. I am running out fo things to look at. I am recieving this error directly on the CAS servers via https://localhost/owa
. The Windows firewall is turned off.
