Using Outlook for Android for personal email and calendar management
Yes, I am aware of that, indeed that is what I did for the account using two-step authentication; it makes no difference at all, both that account, and the one not using two-step authentication, still produce the password issue in BB Hub+.
However, using the Samsung mail app does not have any issues with Hotmail, proving that Hotmail can work fine with at least one 3rd party app, but obviously not with BB Hub+ at the moment.
