  • You need to change the primary domain. To do this:

    1.  Login to the Portal (
    2. On the left, go to more services then search for and select Azure Active Directory
    3. Click "Domains" on the left
    4. When it loads you should see all your domains, along with a check mark indicating the primary
    5. Select the domain  you want to be the new primary, then on the window that loads click "Make Primary"

  • I believe you will need to change them manually I am afraid, I don't think it changes them retrospectively.
