My offshore team is unable to change their JIRA email addresses. They never receive the verification email.
(1) Go to Jira settings.
(2) Change email address to a different company email address. (most people in the company use this email address domain: not the one that the user is currently using).
(3) Message says verification email will be sent, but it never is: not to Spam: not anywhere.
(4) Trigger verification email again from JIRA settings. Email never received.
