I am 2-days old on w10, so still puzzled by it.

office 2016 and onedrive have been installed and activated. onedrive loads on boot.

When I click on onedrive systray icon, the window opens,
Click image for larger version.

And this remains like that, now for 2 hours.

Even sign in options don't appear. Settings are showing most of the fields dimmed, so can't fiddle anything there.

I checked and found that incoming and outgoing rules for windows firewall are enabled and allowed.

I do have a microsoft.live account, but it is not even reaching there.

How to proceed?
