Using OneDrive to autosave Office Documents
Open a document in Microsoft word and click the toggle button labeled “AutoSave” in the top left corner:
A dialogue box will appear asking you to select the account you want to autosave with. Double click your OneDrive account.
A notification will appear in the top left of your screen, and now Microsoft word will now autosave all of your documents through OneDrive.
NOTE: AutoSave is present for files saved in the cloud only (not on your computer hard drive). If you do not see the AutoSave button at the top left of the screen, you can also set up AutoRecover in your app (Word, Excel, PowerPoint, etc.) by going to:
File - Options - Save and adjusting your AutoRecover settings.
