Title
tmpEXO filling up disk -
Description
C: drive is close to be full. The following folder is full of tmpEXO files:
C:\Users\SVCACC_ARS\AppData\Local\Temp
Can these files be safely removed?
-
Cause
These tmpEXO files are normally created by customized scripts.
-
Resolution
A very common reason these files are not deleted occurs when Active Roles connects to Exchange Online using a script module, the script completes but the EXO session is not closed using for instance cmdlet "Disconnect-ExchangeOnline", this keeps building up EXO Powershell sessions that are not correctly closed.
Note that removing these tmp files should not cause any issues, however it is strongly recommend to review all ARS custom scripts to verify any calls to Exchange Online.
