We have a strange problem. After migration of Forefront 2010 from Windows Server 2008 Enterprise to Standard Edition one of the two test users cannot log in (cannot display page) to webmail.

All FW policies, NIC's, IP's has been recreated  from scratch as per old server rules. From my perspective everything is the same.

P.S. Lync mobile FW rule working fine just OWA doesn't work for all users.

Did I missed something?

Check your owa work inside the firewall if it is working fine then there is issue with your firewall or Forefront 2010 rule for OWA.

Yes it's working fine inside also from outside via old enterprise server.
I believe FW is ok because works fine with old Enterpise server also I have checked the logs on our FW and is all green.

P.S. Old and new TMG is virtual machine on the same vmware ESX.

But all the settings in OWA rule looks the same. Where should I look?
