Calendar (El Capitan): If people aren’t receiving your invitations
If people aren’t receiving your Calendar invitations
If you invited people to an event or to share a calendar but guests aren’t receiving your invitations, try these suggestions:
Make sure that your card in Contacts includes all of your email addresses.
If the email address you used to send the invitation isn’t listed, Calendar might not recognize you as the person who created
If you made changes to the event or shared calendar, refresh your calendars.
For shared calendars, make sure your account information is correct in Accounts preferences.
