Sine invitations can be directly integrated with Outlook, Google Calendar and iCal to issue invitations and credentials within a multi-site environment for other hosts who work within that environment.
For this feature to work correctly, you must ensure that:
the email address you are sending the calendar invite from must be the same as your host email address in Sine; and
Email Calendar Invitees must be turned on for your site, to check this navigate to Sites then select Settings for your site and then click Notifications to confirm
