I created a powershell script (AD-Mapping) which runs as scheduled task. Inside this script I want to check for different errors which I would like to write in the EventLog which is automatically created with the task visible inside the tab history.

I know, I can create my own event log with New-EventLog and Write-EvengLog. But how can I use the already existing one?

When I check the existing Event Logs with Get-EventLog * I can see my custom one but I can’t find the EventLog from my Scheduled Task.

PS C:Users**** Get-EventLog *

PS C:Users****> Get-EventLog Microsoft-Windows-TaskScheduler/Operational
Get-EventLog : The event log 'Microsoft-Windows-TaskScheduler/Operational' on computer '.' does not exist.

And I also can’t find any way to write into this one. What’s the difference between the EventLogs from Get-EventLog and the EventLog form the History in the Task Scheduler?
