After you install update rollups on Exchange 2010 it is common to get a blank white OWA page when browsing to the OWA page.
the URL will show something like the following "https://mail.mydomain.com/owa/auth/logon.aspx?url=https://mail.mydomain.com/owa/&reason=0 ."
To fix this issue you must run the Exchange Management Shell and execute the updatecas.ps1 command from the "C:\Program Files\Microsoft\Exchange Server\V14\Bin" folder. This will fix your issue, it causes the owa install to complete correctly.
