Exchange 2007 Update Rollup 9 breaks OWA
Having installed Update Rollup 9 for Exchange 2007 on a number of different sites we finally had one that broke Outlook Web Access. OWA would load yet several images were just placeholders and after logging in no actual inbox could be read as all the Fonts and styling were screwed up.

In our case running the UpdateOWA.ps1 resolved the issue.
FIX:
Step 1) Load the Exchange Management Shell

Step 2) Navigate to your Exchange Bin directory via the management shell - usually C:\Program Files\Microsoft\Exchange Server\Bin
Step 3) Run the UpdateOWA.ps1 script (done by entering .\UpdateOWA.ps1)

Solution worked great for us. Thank you very much!
Rollup-pack 9 deployed with 3.5 .NET updates and Webmail would give a blank screen and javascript error — After running the “UpdateOWA.ps1″ Webmail is back.

Thank you very much. Apparently this has been a problem for every post SP1 rollup since number 5 (it was 9 in my case). There are all sorts of proposed fixes (scary like removing roles and reinstalling IIS).. rather than butcher my production exchange server I just ran this simple script and it worked straight away.
