Calendar sharing - sharing policies apply to mailboxes assigned to them; the default policy covers everyone else.

Required Microsoft Graph permissions

Exchange.ManageAsApp — application permission, granted to the app registration with admin consent.

Endpoints: Get-SharingPolicy · Get-OrganizationRelationship

If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.

Calendar & External Sharing Policy

Can users publish their calendar details or contacts to any outside domain, and which organisations get free/busy information automatically? Detailed calendars reveal meetings, attendees and locations.
