• single Exchange 2010 SP3 UR 26 server;
  • Windows 2012 R2 domain (.local)

Few days ago I started preparations for migration to Office 365 and added certificate and unified Exchange namespace to mail.mydomain.lt.

Suddenly OWA stopped working - it hangs on "waiting" after password input with no timeout.

Authentication works, because if I enter wrong password, I get:

"The user name or password you entered isn't correct. Try entering it again."

I reset OWA virtual directory with these commands:

Remove-OwaVirtualDirectory -Identity 'EXCHSRV\owa (Default Web Site)'

New-OwaVirtualDirectory -InternalUrl 'https://mail.MyDomain.lt/owa' -WebSiteName 'Default Web Site'

with no success.

Any hints how to troubleshoot this issue? Or suggestions for active Exchange related community?
