My app was working properly until Friday but now I am getting "Unable to retrieve user's mysite URL" error ! What is going on?
回答1:
your Office 365 subscription is in locked out state. I expect that it's not only Microsoft Graph calls that don't work, but OneDrive and other Office products can't be used directly either, without an active license.
