When I signed up, I used a family email address. Now, I made my own email account in Microsoft, so I was trying to switch most of my important stuff to this one. When I tried to change it, I got an error that said I was denied access. Anyone know what this means? And does anyone know how to fix it?

If any staff members need to know my email, please message me. I don't want the world to know my email.
