Login forces to use Microsoft

I created an account via invitation of my company. I choose a passwort - everything fine. After logout, I want to login again. I typ my mail adress and when I switch to the passwort field, he automaticly redirects me to the microsoft login page. Why - I don't want this, because the microsoft login is corrupted and doesn't work. How can I login with my adobe password?

To ask this question, I have to create another accout, because I no login is possible.
