Office 365 Outlook connector and calendar permissions requirements

Posted on 19 Mar 2024 14:36:31 by 56

I am using several actions and triggers with the Office 365 Outlook connector.  Primarily I am retrieving calendar events and updating them for a conference room reservation system.  I set it all up using my account and gave myself all the proper permissions through a lot of trial and error.  Now I would like to run this through a service account and I'm having trouble replicating the necessary permissions. I am trying to follow least privileges and not just give the service account every permission under the sun.

 

When I run "Get Calendars (v2)" I cannot get the resource calendars to show up.  This is what I have done so far:

  • Exchange admin center: gave the SA full access to the resource calendar (this also gave the acct "send on behalf")
  • M365 admin center: gave the SA delegate permissions to the resource calendar
  • ran get-mailboxfolderpermission [email]:\calendar and confirmed the SA has "Editor" rights (which is what my acct has)
  • ran get-calendarprocessing and confirmed the SA is listed as a resource delegate

Can anyone help me with what I might be missing?
