Intune script fails "Powershell execution has exceeded defined timeout."

Question

Hi All,

The script only takes backup of Outlook signatures and removes them.

Applied the script through Intune.

The device is marked as compliant.

What might be the reason of the script failing with the result "Powershell execution has exceeded defined timeout."

@X-Box-11-2021, Thanks for posting in Q&A.

From your description, I know you got the error of PowerShell execution has exceeded defined timeout.

Based on my research, the error means a script takes longer to execute than the maximum time allowed by Intune.

Here are some steps you can take to troubleshoot and resolve this issue:

1.Review the script to identify any inefficiencies or unnecessary operations that can be optimized to reduce execution time. Break down the script into smaller parts and test each part individually to identify the slowest sections.

Here are some related issues you can refer to.

2.It is well known that script execution is very slow in Intune and if you want to make it faster, you would need to create win32 app of the script.
