Exchange Server 2003 to Exchange Server 2010 you may encounter an issue with the cas proxy and cas redirection legacy Outlook Web Access URL redirection. When users connect to the Exchange 2010 Client Access server for OWA login they receive a proxy redirect nginx second login prompt for the legacy URL. Authentication prompt when accessing OWA legacy URL No matter which credentials are entered into this authentication dialog box the login is not successful, and a HTTP 500 error is https://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx displayed. HTTP 500 error accessing OWA legacy URL The solution is to enable forms-based authentication on the Exchange 2003 front-end server. This is located in the Properties of the Exchange Virtual Server. Open the Properties of the Exchange Virtual Server In the Settings tab enable forms-based authentication and click OK to apply the change. Enabling Forms-Based Authentication for Exchange 2003 Exchange will warn you that SSL must be configured and IIS restarted if http://exchangeserverpro.com/exchange-2010-owa-legacy-url-redirection-http-500-error/ you are not offloading SSL elsewhere, or have not already configured it in IIS.

Comments Siiby says January 8, 2011 at 5:08 am I have a situation where the Exchange 2003 org (for various reasons that I dont necessarily agree with) have 2 FE servers, one using HTTP and no forms based auth and one using SSL and forms based auth. For other reasons, management refuses to have users redirected to the SSL enabled FE. So, during a co-existence phase with 2010, would this mean that users would HAVE to use the SSL enabled FE? I am negotiating with them on decommisioning the non-SSL FE altogether, as it is on very old hardware. Reply Paul Cunningham says January 8, 2011 at 9:11 am I

Instead of moving everything and renaming and adding certificates, we merely added the exchange 2010 owa CAS as a totally new name. The legacy environment has webmail.domain.com. We opted to test prior to changing our DNS entries. So for our new environment, we are using webmail2.domain.com. We have added a redirect to the legacy boxes for the 2003 mailboxes. The redirect works to the legacy boxes using a new URL (which will eventually become the legacy name during coexistence - mail.domain.com ---which is the webmail.domain.com server). The redirect works, but the users are prompted to login twice. They login to the 2010 OWA and the redirect displays the 2003 OWA login page. I would like single sign on. Another issue is that even when testing the login, it errors out and says that the user can't be authenticated. Is it that the redirect points to a name that hasn't been added to IIS? Forms Based Authentication is enabled on the 2003 servers as well. I hope I explained it well enough. Essentially, we are trying to test the 2010 environment in a production environment prior to changing the DNS entries and chan
