Troubleshooting sync issues

Step 1: Check Connectors health

Go to /connectors/health and look for:

• Backoff (retries delayed)
• Recent error messages
• Last successful sync time

Step 2: Verify credentials

• OAuth connectors: reconnect if tokens expired/revoked.
• App passwords: regenerate if the provider invalidated the password.

Step 3: Trigger a manual sync

Use **Sync now** after fixing the root issue.

Step 4: Confirm results

• Email: open a thread and verify recent messages appear.
• Calendar: open Today view and confirm events match the provider.
