If an Office app closes unexpectedly and you did not a get a chance to save your most recent changes, Document Recovery automatically opens and helps you get your file back the next time you open the Office app.
Note: To decrease the chances of losing your work, make sure that AutoSave and AutoRecover are turned on, and manually save (press Ctrl+S) your file frequently.
Decide which file do I want to save?
If you see multiple files in the Available Files list on the Document Recovery pane and you're not sure which ones to save, the date and creation time of any automatically saved document appears under the document name, which may give you a clue about which file you want to recover. If you see multiple versions of the same file, you'll probably want to open the one with the most recent time because it will have the most recent changes. You can also click each file to open the document and review it. After opening any file in the list, you can continue working in it, and you can close the Document Recovery pane when you have recovered all documents that you want to save.
You can quickly delete unwanted files by clicking the arrow next to the file name, and then clicking Delete.
If you click Close without reviewing all recovered files, you'll see an option to view them again later. The next time you open the application you'll have the option to save or remove those autorecover files.
Yes, I want to view these files later (safest option) - Select this option if you are not sure whether you need the data in the recovered versions of the files.
No, remove the files. I have saved the files I need- Select this option if you are sure you don't need the data in the recovered versions of the files.
