The two VPN clients I used do not work with Outlook and OneDrive. They are working on it. My work hardware VPN works (most of the time) I would ping your VPN provider.

Thanks. Turned out to be a third party block by a company xfinity contracts with. Someone previously had used that VPN IP to send massive amounts of spam. When asked, they lifted the block, and it resumed working again.
