I only recently moved my important folders into OneDrive (involuntarily). And I have Microsoft 365 Home 64-bit on my Win 10 Pro 64-bit (version 1909) home PC.

I've discovered that if "Auto-Save" is on, then merely opening a Word or Excel document will update its "Modified" date to today even if nothing is done to it. That's terrible.

I have turned off "Auto-Save" in both programs, but now I understand that real-time collaboration on a file by myself and another person will no longer be possible.

Is there a way to leave "Auto-Save" on but NOT let it "update" a file's Modified date merely by looking at it?
