When making the initial setup, PowerApps doesn't allow the use of common email accounts (e.g. gmail, outlook), and looks instead for work or school accounts. I created a new domain for myself, thinking I can get around this limitation. However, when I tried to use the email address from my domain (i-ryan.net) I get an error message "This email is part of a reserved domain. Please enter a different email address." I don't get it. Who reserved the domain? It certainly wasn't me! Why can't I use it for PowerApps? Is there a workaround?
