Convert the Legacy DOC File to DOCX Format

Since the older Word 97-2003 (.doc) format lacks support for modern AutoSave capabilities, converting it to the current .docx format will enable the feature.

The legacy DOC format is considered obsolete and does not support the background synchronization required for real-time AutoSave and co-authoring. Updating the file format allows Word to utilize its modern cloud features.

1
Open the Document

Launch Microsoft Word and open the older DOC file that you have saved in OneDrive or SharePoint.

2
Navigate to Save As

Click on the 'File' tab in the top-left corner of the ribbon, then select 'Save As' from the left-hand menu pane.

3
Select the DOCX Format

Choose your current OneDrive or SharePoint location. In the 'Save as type' dropdown menu below the file name, select 'Word Document (*.docx)' and click 'Save'.

4
Enable AutoSave

Once the document refreshes in the new format, locate the AutoSave switch in the top-left corner of the Word window and toggle it to the 'On' position.

Frequently Asked Questions

Can I force AutoSave to work on a DOC file without converting it?

No, Microsoft Word's modern AutoSave feature strictly requires the underlying XML structure of the DOCX format to synchronize changes to OneDrive or SharePoint in real-time.

Why does Word display a warning when opening my older files?

Word displays a warning to notify you that the DOC format is obsolete and that certain modern features, including AutoSave and real-time co-authoring, will be disabled to prevent file corruption.

Will I lose formatting if I convert my DOC file to DOCX?

In almost all cases, converting from DOC to DOCX retains your exact formatting. However, some extremely old Word 97 layout features might be automatically updated to their closest modern equivalents.

What is the difference between AutoSave and AutoRecover?

AutoSave continuously saves your document to the cloud as you type. AutoRecover is a separate feature that saves a temporary local backup at specific intervals (like every 10 minutes) to help you recover data if the application crashes.
