Before retrying, check whether the event already exists on the destination. Repeated saves can create duplicate appointments or conflicting versions. Record the first attempt, retry time, and whether the failure changed from an error to a pending state.
Use a harmless test event rather than a real meeting with attendees. Note source and destination devices, network, broad region, and official status information. If the original event might have synced later, avoid deleting or recreating it until you inspect both calendars. Report a safe timeline to support without exposing private event names or join links.
