If a user has entered a session through a generic link, at the time of access he may be logged in as a GUEST or by entering his name / surname independently. At all subsequent meetings that participant will access, it keeps either the GUEST name or the name / surname / company name entered at the first access. In this case, if the organizer wants to change that name, he will have to change the participant’s personal data, matching the correct name and surname or company name to the email address; then he will have to save the participant in the address book.
