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:
- 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).
- Use DAO to OpenDatabase for shared (non-exclusive) access. Error 3050 (“Could not lock file.”) is thrown and the database is not opened.
- 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.
