This article will outline the causes of the error and provide step-by-step solutions to fix it.

Common Causes of the Error

  1. Multi-User Mode Conflicts: When multiple users try to access the same company file simultaneously, conflicts may arise, causing this error.

  2. Damaged QuickBooks Components: Corrupted or damaged QuickBooks files can trigger the error.

  3. Improper File Closure: If the company file was not closed properly during the last session, QuickBooks may assume the file is still in use.

  5. File Locking by Background Processes: Sometimes, background processes or services may lock the company file, preventing new access.
