SSO to OWA using ADFS 2.1

Hello there,

according to this question,

http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/4b8ee874-8d22-437a-bb37-e5e38f40ab0a

it is not possible to use Exchange 2010SP2 and ADFS 2.0 for OWA. Is there a chance that this constellation is working with the new ADFS 2.1 on Windows Server 2012?

Thanks,

Michael
