powershellscheduled-tasksmapped-drive

Using PowerShell 5.1 on Windows 10, I successfully map a drive, but it doesn't when running by Scheduled Task

The below code successfully create a mapped drive on Windows 10 and 11. Running the script from Task Scheduler doesn't work. The task has been configured to run As System and I have tried the same admin account that is logged on as well. Task has been configured Windows 7 and 2008 R2 and I have tested for Windows 10. The Action in the task is PowerShell.exe -executionpolicy Bypass -file .ps1.

Thanks to anyone who can help. Amos
