Resolving QuickBooks Error 6073 requires a systematic approach. Follow these step-by-step instructions to troubleshoot and fix the issue:

1) Understanding the User Login Issues

  • When encountering Error 6073, it’s essential to assess if the problem is related to user login.

  • Verify that the file is not locked by another user or being used on a different computer.
  • If needed, create a backup of the company file and restore it to resolve any file corruption.

Verify User Access Permission

To troubleshoot this issue, you need to verify and adjust the user permissions and settings within QuickBooks.

Once you access the user settings, review the permissions assigned to each user. Ensure that the user experiencing the Error 6073 has appropriate access rights to the affected company file.

  • Open QuickBooks and log in as the administrator or a user with administrative privileges.
  • Navigate to the “Company” menu and select “Users” or “Set Up Users and Roles” option.
  • Review the permissions assigned to each user.
  • Ensure the user experiencing the Error 6073 has appropriate access rights.
