New Outlook Mail plugin beta

New Outlook Mail plugin beta

What does it mean " Attendee information will not be synced between Outlook and Zoho Calendar"?  Does that mean that no attendee information will be visible in outlook, or does it mean that if I add an attendee in Outlook, that is will not show in Zoho calendar? 

Is this so because the plugin is still in beta and will be work properly in future when it's out of beta?
