OWA breaks after moving mailbox to exch 2010

Not open for further replies.


All my users are on exch 2003. I build a 2010 CAS server, re-directed my webmail.domain.com name space to the new 2010 CAS server. That works fine. The 2010 CAS re-directs exch 2003 OWA to Legacy.domain.com – works great. (EX 2010 windows 2008 R2 and the exchange 2003 is on windows server 2003) CAS server running CAS and HT, separate win 2008 R2 server is mailbox server. My users are using the exch 2010 URL..
But as soon as I MOVE a user"s mailbox from Exch2003 to 2010, the users cannot open OWA. OWA logon just hangs while trying to login. users are able to login to their mapi sessions just fine.
This is happening to all users, regardless of the domain they"re in.
So far I"ve confirmed that permissions on the users accounts are set to inherit.
I"ve added domain users group (domain\domain users) to the local users group – Did not resolve the issue
I"ve confirmed that domain users (in both Domains) have ntfs permissions to the OWA Virtual directory – Still having issues…
What can we try next?
Your help is appreciated!

Assuming you've all the prereq

Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy

Try testing the connectivity using the PS & share the output please

Test-OwaConnectivity -MailboxCredential (get-credential domain\user) -URL https://ExchCASServerName.domain.com/owa -TrustAnySSLCertificate | FL

Everything else on the CAS works fine i.e. Outlook anywhere, autodiscover, mapi, activesync, even OWA all seem to authenticate the user. then as soon as I moved the users mailbox to ex2010, all the above still work except Auth to OWA. The results of your PS command:

Try to access owa using the actual CAS server name...

Also Perform iisreset /noforce

You may have to run above command a couple of times for it to be successful & then Test the connectivity.

You may also move one more user to narrow down if it is an issue with just that user or OWA in general please.

I have tried accessing the actual server name/owa .. Same behavior...

I've moved 3 account and all cant login... same behavior

I've reset IIS multiple times, even rebooted the CAS - no joy....
