What to do
Zoom Rooms calendars connect through Graph with application permissions, Zoom's recommended method. The EWS options are legacy and EWS impersonation is unsupported. Rooms still on an EWS connection need the Office 365 calendar service re-added with Graph API selected; keep the old app on EwsAllowedAppIDs until then.
