Sync health monitoring and notifications

Always-on monitoring

2calendars continuously monitors the health of your sync connections. If something stops working — a revoked authorization, a Google API error, or a connection issue — the system detects it and notifies you.

What is monitored

For each active connection, 2calendars tracks:

• Whether events are syncing successfully
• Whether Google account authorizations are still valid
• Whether there are repeated errors or failures
• The time since the last successful sync

How you are notified

When a problem is detected, 2calendars sends you an email notification. The notification includes:

• Which connection is affected
• What type of issue was detected
• Suggested steps to resolve the problem

Notifications are sent to the email address associated with your 2calendars account.

Common issues detected

• Revoked authorization — You or your Google Workspace administrator removed 2calendars’ access to a connected account. Reconnect the account to resume syncing.
• Google API errors — Temporary issues with Google’s services. These usually resolve on their own. If they persist, check Google’s status page.
• Connection errors — A problem with the sync connection itself. Try deleting and recreating the connection if the issue continues.

Checking connection status

You can view the current health status of all your connections on your dashboard at any time, without waiting for a notification. Each connection shows its current state and the time of its last successful sync.

No silent failures

Traditional calendar sync tools often fail silently — you only discover the problem when you miss a meeting. 2calendars is designed to alert you proactively so you can fix issues before they cause scheduling conflicts.
