Email Failure: Insufficient Permission for 2-Way Sync

If you are seeing an email error that says insufficient permission, it means Gmail is blocking email sending due to missing or revoked permissions.

This usually happens in the following scenarios:

1. Password Changed – Your email password was changed after the integration was set up.

2. Access Revoked – The LeadConnector app’s access was disconnected from your Gmail account settings.

3. Incomplete Permission Granted – At the time of integration, all required permissions (scopes) were not selected when authorizing Gmail access.
   
   

How to Fix This

Step 1: Reconnect 2-Way Sync

• Clear your browser cache and cookies.

• Go to Settings → Email → 2-Way Sync.

• Reconnect your Gmail account and make sure all permissions requested are granted.

Step 2: Remove & Reconnect (if issue persists)

If the error still occurs:

1. Go to your Google Account → Security → Third-party apps with account access.

2. Remove the LeadConnector app.

3. Return to your LeadConnector account and re-connect Gmail for 2-way sync.

This will refresh the connection and resolve insufficient permission issues.

Important Notes

• Always grant all requested permissions during integration.

• If your password changes, you will need to reconnect the integration.

• Ensure the connected Gmail account has the necessary sending/receiving permissions.
