Outlook calendar missing owner permissions

Copper Contributor

Recently I discovered that that ability within OL 2019 via M365 calendar properties when adding a user as an owner or custom doesn't show any longer. All I get is four radial buttons when adding a user. Does anyone know how to make someone an owner from OL calendar please?

That's the expected behavior now. If you want "custom" levels, use PowerShell. Or use a reg key to bring back the old dialog:
You can restore the classic permission options by creating the Following Dword in RegEdit.
DWORD: ShowLegacySharingUX
Value: 1
