Hi @NootNoot, thanks for reaching out! Sorry to hear you're having trouble creating a Udemy account.
You should be able to create a new account using an email from outlook, the only instance where you would have an issue with this is if the same email address is already in use or belongs to a closed account.
If you have another Udemy account with this email that was closed, we can restore it on our system so you can use this email address again to log in. But if this is your first time creating an account with this email, I would recommend reaching out to the Instructor Support team - the team is best equipped to investigate what might be causing this and assist you!
