There's nothing more frustrating than realizing your core outlook calendar not syncing with google calendar correctly, leading to double bookings.
The "Ghost Meeting" Problem
If you are looking for an outlook meetings not showing in google calendar fix, the primary culprit is usually caching delays on Google's end. Native Google imported links only refresh once every 24-48 hours. By utilizing a continuous tool like Calsyncx, those ghost meetings appear immediately.
Token Expirations
Another major reason synchronization drops is due to credential expiration. To successfully keep outlook and google calendar in sync automatically without breaking, always ensure your OAuth permissions to Google remain authorized, and that your Outlook publish link was not reset by global Office 365 domain policies.
