Lock File Problems with Access 16.0.13801.21086

On 12/14/2021, SemiAnnual Enterprise channel updated to version 16.0.13801.21086. This is causing several strange behaviors in Microsoft Access. For example:

  1. Create a new Access database on a network drive or open an existing database from a network drive. Close it. The .laccdb file is not automatically deleted (even though no other users are in it).
  2. Use DAO to OpenDatabase for shared (non-exclusive) access. Error 3050 (“Could not lock file.”) is thrown and the database is not opened.
  3. Databases opened on a network drive appear to always be opened for exclusive access. Once one person has opened a database, others can't--even when opening for shared access.

Reverting to the prior version 16.0.13801.21050 fixes the problem.

This problem seems specific to databases located on a network share. For databases on a local machine, there is no issue.

    I reported it to Microsoft earlier this morning, waiting to hear back.

    Use the application feedback command within Access to send in your comments to the Dev Team.

    Here is the fix that worked for me regarding the shared MSAccess database locked file issue. No MSOffice updates were listed in the "Installed Updates" Control Panel section. (Office 2016 Click2Run Version)

    1.  Close all MSOffice applications

    2.  At an elevated prompt, run the following (with quotes in the path)

    1. "C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update USER displaylevel=True forceappshutdown=true updatetoversion=16.0.14701.20226

    4.  After completed, verify the version number has reverted to the 20226 version (Dec 3rd) listed under the Account settings of the MSOffice application.

    1. Temporarily "Disable Updates" from the MSOffice Account screen and verify your MSAccess database operation.
