A Microsoft file hosting and synchronization service.
The behavior matches a file-lock or read-only condition rather than a macOS file permission problem.
Most relevant causes in this scenario are:
- A Word owner file may still exist after Word did not close cleanly.
- A second Word instance may still be holding the document in the background.
- OneDrive on macOS may be opening an outdated or undiscoverable path because the OneDrive folder path changed to Library > Cloud Storage > OneDrive.
- Antivirus or Protected View can also cause read-only opens.
Based on the details provided, the strongest supported troubleshooting path is:
- Restart the Mac This is specifically recommended for Office files that open read-only and can clear background Word processes or stale owner-file state.
- Open the file from the current OneDrive folder path in Finder In macOS 12.1 and later, OneDrive files are stored under Library > Cloud Storage > OneDrive. Open Finder and browse to that location, or use the OneDrive alias created in the old location. This helps avoid opening a pinned, Recent, or stale path.
- Avoid opening from Recent or pinned entries until the issue is resolved On macOS, pinned files and files in Recent may fail because the OneDrive path moved. Clearing Recents may help prevent reopening an undiscoverable file.
- Check whether Word is reporting the document as locked by another user because an owner file still exists Word can show this when it detects an existing owner file, including after an improper quit or when another Word instance is still running in the background.
- Install Office updates In any Office app, go to Help > Check for Updates, enable Automatically keep Microsoft apps up to date, then select Update and install all available updates.
- If the file still opens read-only, try the general Office recovery steps
The supported sequence is:
- restart the computer
- install Office updates
- perform an Online Repair of Office
- check the internet connection
- If antivirus software is installed, test with its read-only protection settings reviewed Antivirus can cause files to open read-only.
The details that support a lock-related issue are the desktop-only behavior, the temporary nature, and the OneDrive web message that the file is “open by another user.” The fact that web editing works and non-OneDrive folders work also points away from a basic Word licensing or local Finder permission issue.
If opening from Library > Cloud Storage > OneDrive consistently works while Recent, pinned items, or older aliases fail, the issue is likely path-related on macOS. If the file still reopens as read-only even from that current path after a restart and updates, the remaining supported explanation is that Word or OneDrive is still holding a temporary lock on the file.
