Outlook Web Access isn’t working any longer. Iit stopped to work just after the recent Tuesday updates have been applied (not sure if that has anything to do with it).

We're using Exchange 2010, version 14.2 (Build 247.5) SP2

The error message is:
An error occurred and your request couldn't be completed. If the problem continues, contact your helpdesk with this HTTP Status code: 500.

It seems as if the recentMS updates have broken CAS...
The solution was to run the Cas update package in Powershell:
C:\Program Files\Microsoft\Exchange Server\V14\Bin>.\UpdateCas.ps1

This at least restored OWA but it now forces our users to logon twice to OWA (We are publishing OWA through TMG so I will need to do some more work).
