How to Recover Unsaved Offline Edits in a Shared Excel Workbook

Launch the Excel application, click on the 'File' tab in the top left corner, and select 'Open' from the sidebar menu.

Click on 'Recent' and scroll to the very bottom of the recent files list. Click the 'Recover Unsaved Workbooks' button.

A file explorer window will open pointing to the default UnsavedFiles directory. Look for any files ending in .tmp or .xlsb that match the date and time of your offline session.

Open the located file. If it contains your missing edits, immediately go to 'File' > 'Save As' and save it to your desktop with a new name.

Open Windows File Explorer and navigate to the local OneDrive or SharePoint folder where the shared workbook is normally stored.

Look for duplicate files in that directory. The filename will typically be the original workbook name followed by your computer name (e.g., 'Budget_LAPTOP-123.xlsx').

If no conflict file is found, right-click the original shared file or its parent folder, select 'Restore previous versions', and check if Windows created a local shadow copy during your offline editing time.
