We have a few users that are having an issue with file locks NOT appearing on Excel and PowerPoint files.
When these users are onsite and they open an office file that is already opened by another user, they are not prompted to open it in read-only and it appears to open in editable mode. However when they make changes, save, and reopen that file their changes
are gone. If these users are the first to open the file they can modify it fine but to everyone else it DOES NOT appear locked and any changes that other people make are not saved.
All the times this occurred, offline file sync was enabled and on. Once we completely disabled it the problem went away. I'm concerned about this odd behavior and the fact that we do use offline file sync at some of our clients. Any insight as to why this
Try this on one of the clients that are not working:Go to Windows explorer under "Tools" --> "Folder options...", Select the "File types" option. Highlight the word file type (.doc and .docx) and click on the "advanced" button. The value corresponds
to the first check box "Confirm open after download". If you remove this option, the files are opened without any prompt
