Outlook Web Access Error Message in Exchange 2007

Posted on 2010-01-04
Last Modified: 2012-08-14

We are running an Exchange 2007 server and some of our users are experience this error when using OWA.  I did some research on Google and saw there was a hotfix for a 2003 Exchange install, but not for 2007.  Any ideas?

This is a screenshot of the error box:

I have also included the error text verbatim.

    Accepted Solution

    First please try to go to IE-Tools-internet options-advanced-disable script debugging (other) & disable script debugging (Internet Explorer),please ensure that you have tick these two items.


    Then please verify if you have install S/MIME plug-in from Add/Remove.It will be listed under Microsoft Outlook Web Access S/MIME (2007)".If yes, then please uninstall it.


    Also as a workaround, please try to add the TabProcGrowth key to 0. After adding this key you should only see 1 IE process in the task manager instead of 2+ processes. This will be like the behaviors of IE 6/7 that run only under a single process.

    HKCU\Software\Microsoft\Internet Explorer\Main.


    Besides, please apply SP2 with rollup 1 for Exchange Server 2007.
