Is there any error message during this issue?
If yes, please share with us for better analysis.
Then I have following questions:
- How do users access the file server?
Such as UNC path, mapped drive. It is recommended to change the access method to have a test.
- After a user opens the shared file, please check whether the filename has been changed on file server, such as a file begins with: ~$<file name>.
When this issue occurs, please also check to see if any these temporary files be deleted. If these temporary files still exist, the users cannot save shared files normally.
- Can these users download the shared file?
If yes, please let them download one test file, then move it back to file server and replace the pervious one.
