Trigger a message when updating the email of an unmanaged domain to a managed one

Problem Definition

Currently, there is no easy way for a user to know that the domain of the email address will update its account to is managed/verified. That could cause some unwanted side effects such as losing the ability to change the account's email address.

Suggested Solutions

Create a message, such as the example below, that informs the customer that the destination email address is managed by an Organization:

You are about to change your account's email address to a verified domain. With that your account will be managed by the owner of that domain claim from now on. Do you want to proceed?
