The Microsoft Information Store Service (Store.exe) is repeatedly crashing an Exchange 2007 Mailbox Server.
In the application log, we get the following error message and store.exe is crashing due to EXCDO.DLL file:
Faulting application store.exe, version XXXX, time stamp XXXX, faulting module EXCDO.DLL, version XXXX, time stamp XXXX, exception code XXXX, fault offset 0x00000000001ed390, process id 0x1fc8, application start time XXXX.
Have opened up a case with MS PSS and had them analyze the crash dumps. They have identified it as a Bug. The issue is casued by Mac's, Entourage clients that does calendar bookings in the ICS format and the crash is occuring due to Entourage Client accessing a badly created ICS.
MS will provide a fix to this issue in Update Rollup 6.
If anyone is experiencing this issue, make sure you call MS PSS first thing and have them provide the temp bug fix to you.
