Contining saga with Outlook seems to be having a problem

I attempted to access Outlook (hotmail.com) on my wife android tablet.  Of course, she can access her hotmail account on it.  This time it came back and told me there was a problem with my account and that I needed to change my password, which I did.  And then it asked me again to change my password since there was a problem with my new password.  So I did.  And again it came back and asked me to change my password, which I elected not to do and shut it down!!!! So now i have a new password and still CANNOT access my hotmail account.  This is really troubling since I store much of my daily, weekly, and monthly needed data on my hotmail/outlook account.  It is also the only way that I can contact my many associates, many of which I need to have a 'conversation' at least once a week.  When we were plain old hotmail none of these problems ever arose.
