Question :
I am currently editing a Word document on my Mac, and was asked to do so in Review mode, so everybody I will send it to will be able to track the changes I’m suggesting. But with each edit or change I make to the document, my spouse’s name is added to it instead of mine…

As my spouse is in no way involved in the content or the editing and reviewing of this document, I don’t want others to get the impression she might be…

So, how do I fix this ?

Answer :
The problem you are running into is that your spouse has logged in to her Microsoft Account on your MS Office (maybe to reach her OneDrive or something) and she forgot to log out… here’s how to fix this :

To switch the Microsoft Account from MS Office365 (mainly used for school and business accounts) to Office 2021 for Mac (mainly for private use), do this :
– open Word
– in the top menu bar, click on ‘Word’
– in the pulldown menu that appears, click on ‘Sign Out’

When done, the ‘Sign Out’ option will disappear from the pull down menu, and no ‘Sign In’ option will appear there… so you need to use a different route :
– open Word
– in the top menu bar, click ‘File’
– in the pull down menu that appears, click on ‘New from Template…’
– in the new window that opens, click on the ‘Sign In’ button top-left
– now a login window will open where you can use various ways of signing in (if you have the MS Authenticator app on your iPhone, the easiest way is to select that option to login)
– when logged in, your name and initials will appear in the place where the ‘Sign In’ button used to be

That’s it !
enjoy 😉
