At the moment Karbon doesn't manage calendar invites. Until we integrate with Google and Outlook calendars, this is how you can manage them:
On the same screen you see Karbon, have another tab open for your calendar
You will receive the invite in your Triage; you will be able to click on the links but you will be redirected to the calendar tab; ie, you must accept the in invitation in your calendar.
Back in Triage, clear the email.
