Tested on : Plesk Obsidian, Windows 2012 R2 Few days back i was looking into a way to find the cron details of a customer and once its fetched remove the crons created by that user. Through GUI, it can be done in 2 ways : 1. Go to Tools & Settings > Scheduler Tasks -or- Domains > Schedule Tasks 2. Login to the server > Open Task scheduler (taskschd) and Look into the task with description. You will get the domain id there But the above mentioned process is quite cumbersome. So after digging a lot, I was able to figure it out using Powershell. To get all the cron details of a particular Customer : & "$Env:Plesk_Bin\Crontabmng.exe" get "CustomerName" To Remove all the crons of a particular Customer : & "$Env:Plesk_Bin\Crontabmng.exe" remove "CustomerName"
