Hello @Dr. M. Isabelle Dugast,
Thank you for your question and for explaining your situation so clearly. I completely understand how useful the “Pick up where you left off” feature can be, especially when working on long documents.
Based on my research and testing, this functionality works when two conditions are met:
- You are signed in with your Microsoft account in Word.
- The document is saved on OneDrive or SharePoint.
When these conditions are in place, Word will automatically display a prompt such as “Welcome back, pick up where you left off” or a small bookmark icon on the right-hand side of the scroll bar when you reopen the document. Please note that this prompt may only stay visible for a few seconds.
I tested this on my side with a file saved on OneDrive while signed in to a Microsoft account, and the feature worked as expected.


Unfortunately, there is no permanent setting to enable this feature for local files only, as it relies on cloud synchronization to track your last position.
To assist you further, could you please confirm whether you are signed in with a Microsoft account and if your document is stored on OneDrive or SharePoint? I look forward to your response so I can assist you further if possible.
Best regards,
