Thank you!!!!
I have been (None stop) having the EXACT SAME issues! When i tried to ask Microsoft for help I received EXACTLY the same treatment. They even went so far as to say i was not expressing my problems correctly, telling them what i needed help with, or what the main issue was. I felt as if I was absolutely ignorant.
I have, and they have, reinstalled and reset OneDrive, Office, Windows Store, Windows Update, and Windows 10 (Everything possible, I think). I am so sick of having to reinstall all my software and apps, i have finally just given up.
I want to thank you for your post. The issues and Microsoft had me thinking i was crazy and imagining the problems.
