We would like to automate the process of injecting calendar items into people's calendar without their input by Organizational Unit. Examples of the use would be holiday calendar for the entire organization or Mandatory meeting for Finance OU. We use Exchange Online/o365/Azure AD. We are looking for detailed instructions on connecting to EMC, how to modify the variables to suit the calendar item we want to inject and how to execute the code. The instructions need to be detailed enough to allow execution by an IT student with no EMC experience.
