I'm attempting to change the environment system variable TEMP and TMP to a different location other than the system drive as recommended my Microsoft (http://technet.microsoft.com/en-us/library/aa996133.aspx
The issue is that when I make this change I can no longer mount any of the mail stores. The information store is running but I get the error "An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724
Exchange System Manager"
I have tried following instructions detailed here http://technet.microsoft.com/en-us/library/aa996027(EXCHG.65).aspx
but without success.
The only way i have been able to fix the stores is by running a eseutil recovery and defrag.
If I switch the TEMP and TMP locations back to original and reboot, stores mount fine.
This seems like a simple change. Is there anything I need to do prior to making this change so the stores will remount?
