4 Best Ways to Fix “Access File Locked by Another User” Error
Are you facing the “MS Access database locked by another user” issue when trying to open, modify, or share MDB & ACCDB files? This usually occurs when another person has opened the database, an active session is running in the background, or a leftover lock file prevents access. Sometimes, incorrect password or folder permissions can also trigger this problem, which restricts users from making changes to the file.
In this blog post, we will explore easy, effective techniques to fix the “Access file locked by another user” error and regain access to .mdb & .accdb files. To resolve the problem, you need to identify the exact cause and then apply the suitable method to access locked files. Now, let’s get started.
Why Does “MS Access File Locked by Another User” Issue Occur?
The Access file locked by another user error appears due to multiple reasons related to database use, file permissions, or other system settings. Understanding the root causes helps you find the source of the problem and choose an appropriate solution. Here are some main reasons explained:
- Database in Use: When someone else has opened the MDB or ACCDB database in exclusive mode or is actively using it.
- Leftover Files: Temporary files may remain in the database after unexpected shutdowns or application crashes; this causes locking issues.
- Insufficient Permissions: Users may not have required permissions to read, edit, view, and share MDB and ACCDB database folders.
- Active Sessions: If any session is running in the background, this can hold a lock on the entire database.
- Internet Connectivity: Unstable network connections or interrupted access to a shared database file can prevent Access from releasing locks.
- Incorrect Database Closure: Closing the system suddenly, forcing Microsoft Access to shut down, or a sudden power failure may leave the database locked.
- Password Restrictions: A secured database file restricts access to unauthorized users. If the correct credentials are unavailable, then users are not allowed to use MDB or ACCDB file.
Before applying any approach, create a backup of original MDB or ACCDB database file to safeguard important information. Now, it’s time to find out the right troubleshooting methods below to restore access and streamline the workflow.

If some other user or a background Access process is using the database, you are not allowed to open or modify the folder. Now, follow the quick steps to open Access database file:
- Ask all members to save their changes & close the database.
- Now, open Task Manager and look for any remaining MS Access processes.
- Lastly, reopen the database and check whether the issue is resolved ot not.
Note: Try not to end an ongoing process while another user has unsaved changes, as it can lead to data leakage when you fix the “Access file locked by another user error.
#2 Remove and Check Leftover Lock MDB/ACCDB Files
MS Access generates temporary locking files when a database is opened. There are usually two files that have the .laccdb extension for ACCDB files and .ldb for MDB database files. So, here are the easy instructions mentioned below:
- Close the entire database on every PC that is using it.
- Now, open the folder that contains MDB and ACCDB files.
- Look for temporary files with both extensions.
- Confirm that no other user is still using the database.
- Finally, try to delete the lock files temporarily.
Note: Do not delete the file permanently while the database is in use. Access normally removes it when the last user closes the entire database. If the file cannot be deleted, then identify active sessions and permissions.
#3 Verify Folder Permissions Properly
When you need to access, edit, open, or update the database, it requires appropriate permissions to use shared files and to remove or create its locking file. Follow the step-by-step instructions to understand how to do it:
- Move to the folder containing your database.
- Now, right-click on it and select Properties icon.
- Open the Security tab from the dashboard.
- Choose your Windows user account to check file permissions.
- Confirm that you have all the access permissions, such as modify, read, or write.
- If the database is stored on shared network share, then ask the administrator to verify both folder sharing and security permissions.
Note: Reopen the MS Access database after correcting permission errors. Try to avoid offering full control to everyone and assign only the access required for authorized users.
Limitations of Using Manual Approaches
