I agree with David..."it must involve OneDrive and how Word interacts with that server-based data". My recent list functionality also has returned without an update. Yesterday, I totally uninstalled One Drive as I've always been suspect of it anyways. This didn't help. Today everything is fixed however, when I click the Open icon, "OneDrive - personal" is still displayed. If I click on it and right-click the folder and select "Copy path to clipboard" and paste it to notepad, it displays "https://d.docs.live.net/........". If I paste the URL into a browser, it brings me to One Drive online with my account info.
Hey, Microsoft. I do not want One Drive! I have uninstalled it. Do not host web space for files from my computer. I do not want this!
One other note. I never "Stay logged in" when signing into Microsoft and until yesterday everything has worked fine. Now, I can no longer run an Office app that's installed on my PC without being logged in to my Microsoft accoutn. Hmmmm. Cut it out Microsoft!
You cannot stop OneDrive from being reinstalled as its part of Windows and if its files are missing, it will automatically reinstall it. To keep it from LOADING up you need to disable it via Task Manager on the "Startup" tab by right-clicking and selecting "Disable".
