QuickBooks company file opens read only on one workstation

Scenario

Only one user opens the company file in read-only mode while everyone else works normally.

Recommended Resolution Path

1. Check whether the workstation cached the file locally or lost proper share permissions.
2. Verify the user is not opening a copied file from a sync folder or Downloads.
3. Compare mapped drive versus UNC behavior.
4. Document the correct launch path for the team so duplicates do not creep in.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
