Automatic update holidays in AutoAttendant!

AlexanderHolmeset 

Thanx we are using this option & evolved it an little bit..

We are (ab)using the holliday's to enabel our user te implement an custom message when the phone Auto attendant is unmanned. (day off for example). We've enhaced the option with

- replace the forms input tot an sharepoint-powerapp input  (runbook action)

- The hollidayname (script) is automaticly renamed  to <username>-<AA-name>- User_input_name
f.a. mbs02-ITdeptAA-sickday

- We've made an an powerapp to controll who can choose which AA, so not everyone can set an holliday for other departments..

The sollution is an great succes... but..

Now we would like to automatic clean up the hollidays in our enviroment.

Idealy once a week an scheduled task to erase all expired "hollidays" .

Do you have any idea how to schedule/ powershell this option?
