The Add a Person dialog opens.
Enter the Name and Email of the external user you want to add.
Select External and click Add and Send Invite.
Access the event to which you want to add the new user, and add them to the appropriate field (for example, Presenters).
Save the event.
The external user is added to the event.

Notifications and invites for external users
External users cannot log into PlusPlus, but they still get calendar and email notifications if you an enable the setting to do so.
Please be aware that there is not bidirectional Google calendar capability due to Google permissions so anything added to a plusplus item, such as a calendar invite, will not stick and will be removed.
To enable this, go to Settings > Security > General and turn on Allow external users to receive notifications and calendar invites.
Note that only admins have privileges to change the system settings. Content owners and admins can add new users, including external ones.
External user profiles
When you add an external user to an event, a profile for that user is created in PlusPlus and you can access it from the People dashboard.
