Is it possible to prevent a scheduled task to run, if the previous run is still in progress?

Hello, We have a task which checks every hour if jobs have been added to a list (CSV-File) and if so will start provisioning tasks including Microsoft Teams.

If there are many entries it could take more than an hour (especially the microsoft teams task may take a while) and the the next run of the scheduled task starts to run.

It would be great if we could add a condition or check withing the script, if the previous job has completed or is still running to prevent duplicate runs. Is this somehow possible?

Hello,

Sorry for the confusion, but we are not sure what exactly makes you think a scheduled task run starts while the previous one is still in action. It is generally impossible as the next run time is calculated from the moment the previous run ends, not from the time it begins.

Hm that's good to know. So it may have been a human error.. . I'm quite sure i had the situation, that the script was starting even it was running already. Could it be that if i start the task manually with "Run Now", that it does not update the schedule?

Hello,

I'm quite sure i had the situation, that the script was starting even it was running already.

A script running and a scheduled task running are totally separate and unrelated things. For example, if your scheduled task runs a script that initiates an external process, the scheduled task execution will be completed within a few seconds, but the external process will keep running. If that is your case, you need to use a script condition in the task. The condition should check the external process status and be met only if the process is not running.

Could it be that if i start the task manually with "Run Now", that it does not update the schedule?

No, you can see that by viewing the Next run property of the scheduled task.
