A provider that instructs setup using POP and only offers 50MB storage should be avoided. Strongly suggest an adding an outlook.com or gmail account (if they don't already have one e.g. on their phone) and that they transition to it.
Having the old and new email address set up in the mail client makes the transition easy, means the old one can be monitored for years to come if needed.
