Changing user names
Rename the First Name, Last Name, or email username (for example, name@domain.com -> fnamelname@domain.com) on an active order domain. The domain stays; only the inbox names change. Use this when the user’s names are wrong or need to be changed.
Each inbox address is derived from its persona’s names (for example,
Jane + Doe becomes jane.doe@domain.com); you provide names, not
addresses. profile_picture_url is accepted for forward
compatibility but is not currently applied to inboxes.
