Help and Support:


Edited C:\Program Files\Microsoft\Exchange Server\V14\Scripts\ManageScheduledTask.ps1

and changed line 462 to write-output instead of return.

Exchange 2010 & Windows Server 2012 exchange management console crash.

Trying to gather data from the exchange console kept getting: error FX:{A5406CA3-6393-48a0-8827-CF06F0C94C55} Exception has been thrown by the target of an invocation.

Everything showed "Unavailable".

Fix is here:

Open mmc, add the exchange management console snap in and save it as emc.msc

create a bat file 

set COMPLUS_Version=v2.0.50727

and the management console will work.
