Hi,
Thank you for posting in Microsoft Q&A forum.
Per my experience, when we use Retire action, email profiles that are provisioned through Intune are removed. And cached email on the device is deleted.
If you need further help, it is suggested to create an online support ticket to get more help. Here is the support link:

Thanks for your understanding and hope everything goes well with you.
Best regards,
Simon
