When an admin changes a user’s email in the System Console> Users or via CLI command, there is no feedback to them that a user needs to confirm the change via email before the email is actually changed.
Propose we add a pop up modal in the UI and a message after running the CLI command:
An email has been sent to the user at the new email address entered. Once they confirm the new email address the email will be updated in Mattermost. The user will be prevented from using the old email address to sign in until the new email address is confirmed.
