Access to Outlook

I inadvertently changed my birthdate on my profile and now Outlook recognizes me as a child needing my parents permission to get access to my emails.  I created another account for myself as a parent, and was able to give permission to sign into the account.  However, I tried to log Outlook through my phone app and its again denying me permission as a child.  Any thoughts on how to change my birthdate back so that I am an adult again so I can access Outlook on my phone and tablet?  Thanks a bunch!!!
