DESK81 Error in QuickBooks Desktop Integration

If you see the error:

DESK81 Error: You do not have permission to access QuickBooks Desktop company file.

This means QuickBooks Web Connector does not have permission to access the QuickBooks company file.

This is a permissions issue between QuickBooks Desktop and the Workspace.

• QuickBooks Web Connector is not authorized to log in automatically.
• The integration permissions were changed or removed.
