If you decide you do want to save the changes, just turn AutoSave back on. Then click No when you are asked to save. If the changes are meant to be temporary and not saved, close the file. Unfortunately, the hack works only in Office 365 ProPlus. The easy way is to turn the AutoSave switch off before you make your changes. That's according to a Microsoft support article.

If you're equally miffed, there's one more option: You can disable AutoSave by tweaking the Windows registry. If you want to turn AutoSave off, by default, for all files, go to File > Options > Save and uncheck the box next to AutoSave OneDrive and SharePoint Online. Plenty of web and mobile apps present users with informative overlays when introducing them to new features. I wouldn't be so miffed about this if Microsoft had notified me first. What if I make changes and then decide to abandon them? Now I've got an unnecessary, unwanted copy I have to manually delete. Microsoft recommends that when you open an existing document with the intention of saving it with a different filename, you use the new "Save a Copy" option (which is what replaced "Save As") before you make any changes. There's another way to work around this, but it means changing the way you work, and probably have worked for decades. Sure, you can turn off AutoSave - but only if you turn off automatic backups as well. If you're willing to do that, click File > Options > Save, then clear the checkbox next to "Save AutoRecover information every X minutes." That effectively disables AutoSave - while also leaving you without the aforementioned backup. What you can do is turn off AutoRecover, the feature that automatically creates a backup at regular intervals.
There's no way to globally disable AutoSave. It gets worse: Although you can easily turn off the new AutoSave feature by clicking the little toggle in the upper-left corner of the screen, that turns it off only for the current document.
