Hello!
Why am I told that my account needs to be linked to a valid email before activating a sandbox?
The email address your Microsoft account is linked to must be verified to prevent abuse of the Learn sandboxes. As a result, some known disposable email providers (including .onmicrosoft.com
) are blocked. The recommendation is to use an account with an email provider that requires additional security measures during activation. I hope this helps!
