If you use Outlook 2016 for Mac users with Google Gmail or G Suite, you have the following options to synchronise your calendar/s across multiple devices and LawTap.

Option 1 - Use Mac Calendar.app as your calendar

This means that you will need to use the Mac Calendar.app (and not Outlook for Mac 2016) to manage your calendar and keep it synchronised between your iPhone/Android smartphone, computer and LawTap. See also:
