SCCM Package with Powershell script to read from sharepoint

Hi All,

i have a powershell script that reads from an Excel file on sharepoint and update my calendar with shifts events. it simply create tasks on my calendar according to what present in excel sheets.

when running the script from my desktop with my user rights (normal user rights -  not admin) the script runs and updates my outlook calendar but when i setup a package on SCCM and set the script to run with user rights  nothing happens when i run it from software center. it runs actually but no updates to my calendar.

any ideas on what could be the Problem / Solution.

I have full access to SCCM so any suggestions can be done and any help is appreciated.

Regards to all
