OWA Exchange 2010 does not connect to Exchange 2003 Mailboxes
-
Wednesday, February 10, 2010 4:01 PMHi everybody,
I've spent two days now trying to solve the following problem. I want to transition from an Exchange 2003 Server to the new Exchange 2010 on a Windows Server 2008 R2. I've consulted the book 'Exchange Server 2010 unleashed', so I first installed the CAS roll and now try to confirm that OWA is possible.
When I connect to https://mydomain/OWA I get the logon screen of OWA, which looks good so far. However, when I enter my logon credentials (Mydomain\User) I get the following error:
"Your request cannot be processed as no server with the correct security settings can be found to process the request. If the problem persists please contact your helpdesk."
(My actual error message is German: "Ihre Anforderung konnte nicht ausgeführt werden, da kein Server mit den richtigen Sicherheitseinstellungen gefunden wurde, um die Anforderung zu verarbeiten. Wenn das Problem weiterhin besteht, wenden Sie sich an den Helpdesk.")
I couldn't find any online resources regarding this error. I assume I missed some configuration that tells the new Exchange Server 2010 to redirect the OWA requests to the old server. I didn't do any configuration besides setting up CAS yet (no 2010 hub server or mailbox server), however in the Exchange Management Console everything looks good as far as I can tell. E.g. all mailboxes are listed as legacy mailboxes and so on.
Has anyone had a similar issue?
Kind regards
Till

Friday, February 12, 2010 12:46 PM Ok, I solved my own Problem.
Apparently the new Exchange 2010 Server's OWA wanted to redirect to the old Exchange 2003 OWA, but I had to manually configure the address of the old OWA. I still don't know why the tab "Exchange 2003 URL" isn't visible in the properties menu of my Exchange 2010 OWA in the EMC. I had to configure this manually:
Set-OwaVirtualDirectory "owa (Default Web Site)" -Exchange2003Url "https://exch2003.mydomain.com/exchange"
This did the trick. Now, when I enter my correct logon credentials at the new OWA I'm redirected to the old OWA.- Marked As Answer by T. Radermacher Tuesday, February 16, 2010 7:25 AM

Thursday, February 11, 2010 1:04 PMThanks for your fast reply. I'll give it a try, although I don't understand why these new hostnames are mandatory.
When i connect to the OWA of the new Exchange 2010 (exch2010.mydomain.com/owa), why doesn't it forward these requests to old Exchange 2003 (exch2003.mydomain.com/exchange)? And why would a certificate and new hostname for the old Exchange 2003 change this?
Edit:
Thank you for the Exchange 2010 Deployment Checklist, Brian. Very helpful indeed. Currently I get to the step 'Configure settings on virtual directories. However, there is no tab called 'Exchange2003URL' in the Properties of my OWA directory (in the EMC under server configuration --> client access --> myEx2010Server --> Outlook Web App tab).
Later in that step when i try to verify my configuration I get the same error I reported above. I try to connect to my new servers OWA using the public computer option, but after I entered my logon credentials the error "Your request cannot be processed as no server with the correct security settings can be found to process the request. If the problem persists please contact your helpdesk." shows up.
Could one reason for this be, that my Exchange 2003 isn't properly connected to my new Exchange 2010? When I try to enter the Exchange 2003 Url for my OWA via the EMS i get this error:
[PS] C:\Windows\system32>Set-OwaVirtualDirectory \OWA* -ExternalUrl https://exch2010.mydomain.com/owa -Exchange2003Url https://exch2003.mydomain.com/exchange
The transformation for the parameter "Identity" can't be processed. The value "\OWA*" can't be converted to the type "Microsoft.Exchange.Configuration.Tasks.VirtualDirectoryIdParameter". Error: "'\OWA*' is no valid value for the identity.
Parametername: Identity"
