A family of Microsoft word processing software products for creating web, email, and print documents.
Sign in to OneDrive in your browser and see if the Version History can be used to recover the document version you need.
Note that if your document was saved locally (not to the OneDrive cloud), no true automatic saves are made. Instead, what you have is the "Save AutoRecover information every X minutes" option (File > Options > Save). If Word has crashed, you should see the recovery pane; if there was no crash, Word will usually have discarded the autorecover (.asd) files. You can always search your C:\ drive for .asd files that may have been left behind and see if you can open them via File > Open > Browse in Word.
