Why did a calendar stop syncing?

Start by checking one expected upcoming event. Compare its listing on Sync2Cal with the calendar app where you expect to see it. This separates a missing schedule from a delivery problem.

1. Check whether one calendar or every calendar is affected

If only one calendar is affected, open its public Sync2Cal page and look for upcoming events. A season break, an unannounced schedule, or a source problem can leave a calendar without future events. An empty event list alone does not establish which explanation applies.

If several calendars stopped at once, check your account access and the connection to Google or Outlook. If events appear on a computer but not your phone, use the multiple-device checklist.

2. Check your plan and subscription

Open My Account and review the Subscription section. If your trial or paid access ended, some or all calendars may be paused according to your account's allowance. Refreshing the calendar app does not restore expired access.

Open My Calendars from your profile menu and check that the schedule is still synced. A saved calendar that is not synced does not deliver events to your calendar app. See managing your calendars.

3. Check the delivery method

• Connected Google account: check Integrations in My Account. Reconnect if it actually shows disconnected, then check a known event. See Google connection help.
• Connected Microsoft account: check the Outlook integration and the Microsoft account you authorized. See Outlook troubleshooting.
• Calendar subscription link: your app fetches updates from the link. Check that the subscription is still present and visible. See how often calendars update.
• Downloaded ICS file: a file import does not receive new events or schedule changes. Use a subscription or account connection for ongoing updates.

4. Use Resync for the affected calendar

In My Calendars, open the calendar's menu and choose Resync to reopen its setup flow. Complete the steps for your intended destination, then check an event in that destination.

Resync cannot make an unannounced fixture available, correct an upstream schedule, or force every calendar app to fetch a subscription immediately. Avoid repeatedly adding new copies or disconnecting all your calendars while diagnosing one schedule.

5. Report the specific mismatch

If the event is missing or incorrect on Sync2Cal, report the source discrepancy. If it is correct on Sync2Cal but absent in your calendar, include your calendar app, connection method, and whether other schedules still update.

You can email hello@sync2cal.com. Include the public calendar page rather than your private subscription URL.
