EMC Crash with exception “FX:{A5406CA3-6393-48a0-8827-CF06F0C94C55}”

There has been many instances where the Exchange Management console crashes when I used to work on Exchange Servers, particularly on Exchange Server 2010. Most of the time the issue gets resolved when you end the task from Task Manager and launch a new session.

However, in this particular Exchange Server I was working with, the MMC kept on crashing throwing exceptions. This post provides the steps to resolve a similar issue.

The Exception I kept on getting is shown below :

FX:{A5406CA3-6393-48a0-8827-CF06F0C94C55}

This issue can be resolved with the help of a small .bat script..

All you have to do is in a notepad copy the below script and save it in .bat format.

set __COMPAT_LAYER=RUNASINVOKER
set COMPLUS_Version=v2.0.50727
“C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc”

Execute the script and confirm the working of EMC.

Error “Outlook Web App didn’t initialize. If the problem continues, please contact your helpdesk.”

Recently, I faced an issue logging in to OWA on our client’s Exchange 2010 server. The error reported was as follows :

Outlook Web App didn’t initialize. If the problem continues, please contact your helpdesk.
Couldn’t find a base theme (folder name=base)

Initial troubleshooting steps were taken, like restarting the Microsoft Exchange Form Based Authentication service, re-creating OWA virtual directories etc..

Upon further researching on the issue, I found a similar post online where the OWA crashed after installing the Exchange updates..

So, in order to resolve the issue all you need to do is launch Exchange Management Shell, navigate to the location C:\Program Files\Microsoft\Exchange Server\V14\Bin and then execute the power shell script UpdateCas.ps1.

This script will find your OWA/ECP virtual directories, update them and make some modifications to metabase etc.. Once completed, you will be able to access your OWA/ECP like before.. 🙂
