Well, we have a problem in our migration szenario at the moment. We are planning to migrate from Exchange 2007 sp2 to Exchange 2010 sp1 and for having a test phase we want to do it in 2 steps. The first step is to migrate our CAS-Servers to 2010. So this means the mailboxes still are in our Exchange 2007 environment.
Both CAS-Servers 2007 and 2010 see each other and know each other.

In this case we need a correct proxying between the CAS-Servers 2010 and 2007. This works fine, except the proxying with mobile phones via Active Sync. There we get an error when we want to log on via the new CAS-Servers to our Mailbox which is still in the MBX-Server 2007. Our logfile in CAS-Server 2007 says the following:
2010-09-30 08:26:14 W3SVC1 10.156.54.23 OPTIONS /Microsoft-Server-ActiveSync/Proxy User=a2824ck&DeviceId=HTCAnd8e227b39&DeviceType=htcbravo 443 - 10.156.54.141 Android-EAS/0.1 401 2 2148074254

2010-09-30 08:26:14 W3SVC1 10.156.54.23 POST /Microsoft-Server-ActiveSync/Proxy cmd=ProxyLogin 443 - 10.156.54.141 - 401 1 0
2010-09-30 08:26:14 W3SVC1 10.156.54.23 POST /Microsoft-Server-ActiveSync/Proxy cmd=ProxyLogin&Log=PrxFrom:10.156.54.141_Error:LackingExtendedRights_ 443 ADS\BADWLRZ-SWCAS1$ 10.156.54.141 - 403 0 0

So the Error is: Lacking Extended Rights (or this says the logfile)

Our question is now: What´s the problem? How can we solve this issue?

On the 2007 server, did you turn on FBA and BasicAuthentication on the OWA virtual directory? (identical to Ex2010)

E.g. Set-OwaVirtualDirectory -Identity "CASSERVER\OWA (Default Web Site)" -ExternalURL https://legacy.externalurl.com/owa -FormsAuthentication $True -BasicAuthentication $True
