How to Fix QuickBooks Error -6073, -99001?

The QuickBooks -6073 -99001 error can occur when multiple users try to open the company file at the same time. It usually occurs if QuickBooks fails to read the company file.

Due to this error, you may fail to open the company file, thus disrupting invoicing, payroll processing, and other financial tasks, in QuickBooks associated with the company file.

Causes of QuickBooks Error -6073, -99001
