To turn on AutoSave in desktop Word for Microsoft 365, save the document to OneDrive or SharePoint Online, reopen that cloud copy if needed, and set the AutoSave switch near the top of Word to On. Confirm that Word shows the intended cloud location and a saved or syncing status. AutoSave continually saves eligible cloud files as you edit; AutoRecover is a different crash-recovery feature for local and cloud work.
Turn on AutoSave for a Word document
- Sign in to Word. Use the Microsoft account or work account that has access to your intended OneDrive or SharePoint location.
- Save the file in the cloud. Choose File > Save a Copy or the location control, then select OneDrive or SharePoint Online. Name the copy clearly. If you are starting a new document, save it to that cloud location before relying on AutoSave.
- Open the cloud copy. Check the file name and location so you do not keep editing a local duplicate. Microsoft notes that on some Macs, opening from Word’s online locations matters for AutoSave eligibility.
- Turn on the switch. In desktop Word for Microsoft 365, set AutoSave near the top of the window to On if it is not already on.
- Confirm it is working. Make a small harmless edit and check Word’s saved or syncing indication. Open Version History later if you need to inspect a retained earlier state; it is not a record of every keystroke.
Microsoft says AutoSave is enabled by default for eligible Microsoft 365 files on OneDrive or SharePoint Online. You may find it already on after moving a file there. Do not assume a toggle alone makes a local-only file eligible.
What if the switch is missing, off, or gray?
| Check | Why it matters | Next step |
|---|---|---|
| File location | A local folder or unsupported server does not provide Microsoft 365 cloud AutoSave | Save a copy to OneDrive or SharePoint Online |
| Account and editing access | You may have opened a file through the wrong account or without edit permission | Open the cloud file from the account that can edit it |
| File format and sync | Older formats and paused OneDrive syncing can disable AutoSave | Check the format and resume sync, then reopen the file |
| Application | The desktop AutoSave toggle is a Microsoft 365 app feature | Check your Word version; Word for the web saves its cloud file automatically |
If AutoSave still does not appear, check Microsoft’s AutoSave eligibility guidance. An organization may also control available app versions or policies. Continue to save manually while troubleshooting.
Windows, Mac, and Word for the web
Windows desktop: Use Word for Microsoft 365, open the OneDrive or SharePoint file, and check the switch near the upper left. If your app has a default-setting checkbox, Microsoft documents it at File > Options > Save. That setting is different from the switch for the current file.
Mac desktop: Use Word for Microsoft 365 for Mac, open the cloud file through Word’s online locations, and check AutoSave. Microsoft documents a separate default preference at Word > Preferences > Save. If you are working on a local file, use Command+S until you move it to an eligible cloud location.
Word for the web: The document already lives in OneDrive or SharePoint, and Word saves changes to that cloud file automatically. Make a copy before experimenting if you want to preserve the original unchanged.
Protect the original before experimenting
With AutoSave on, your edits go into the cloud file as you work. If you intend to test a new layout or rewrite a document without changing the original, choose Save a Copy first and edit the copy. If changes were already saved to the original, inspect Version History to see whether an earlier version is available. Our Word Version History guide explains how to inspect it before restoring anything.
AutoSave is not AutoRecover
AutoRecover periodically creates recovery information in case Word or the computer closes unexpectedly. It does not mean every unsaved word is safely stored, and it is not the same as continuous cloud AutoSave. If you are trying to find missing work rather than turn on saving, use our unsaved Word document recovery guide. To stop continuous cloud saving for one file, see how to turn off AutoSave.
