I am running Exchange 2010 and 2003 in coexistence, and recently switched to using Exchange 2010 as my OWA server. User mailboxes are still on 2003.
Almost everything works fine, except that when users click the "Log Off" button in OWA 2003, they get a 404 error. Exchange 2010 OWA users have no problem logging off.
Exch 10 CAS: mail.company.com (This is an NLB, if it matters). Exch 2003 Front End: legacy.company.com
Outlook Web Access/App works fine for both 2003 and 2010 users. Users can successfully login and view their mailboxes on the legacy 2003 side through the 2010 CAS. I don't have any certificate errors.
- The 2003 OWA log Off button has the following URL: https://legacy.company.com/exchange/mailboxname/?Cmd=logoff
- When I click the log off button in legacy 2003 OWA, I am redirected to the following URL and a 404 not found error: https://mail.company.com/exchweb/bin/auth/owalogon.asp?url=https://mail.company.com/exchange/&reason=1
The mail URL refers to Exchange 2010, which uses a Virtual Directory to /owa for /exchweb. There is no /bin/auth/owalogon.asp file in the Exchange 2010 directory structure. That file/directory structure DOES exist on the 2003 side, but the log off button redirects to mail, not to legacy I tried copying the 2003 /bin/auth directory over to 2010, but that didn't work.
Has anyone seen this behavior? Are your OWA 2003 log off URLs different? Any idea if I can customize the logoff command in Exchange 2003 to forward to a working log off page? Any other ideas on how to address the issue? My searches have turned up nothing.
