Hours of useless support calls got me nowhere. The official MS support and recovery tool kept failing to update my office 365 to modern. I came across this article, followed to the correct registry key, and changed it (it already existed) from 0 to 1. Boom. Problem solved. Thank you for saving my sanity!
