VSTO tools Outlook 2010 differentiate between Appointment and Meeting

Question

How can I know if a new meeting was clicked or new Appointment was clicked in Outlook 2010? I have a ribbon class in which by looking at RibbonBase.RibbonId I can make out if it's Microsoft.Outlook.Mail or Microsoft.Outlook.Appointment however for Appointment item click and Meeting item click the Ribbon Id holds the value Microsoft.Outlook.Appointment. Is there any way to differentiate between Appointments and meetings selection in outlook?

Thanks

Answer 1

You are correct that Outlook uses the same Ribbon ID (Microsoft.Outlook.Appointment) for both Appointments and Meeting items.

To determine which appointment type, AppointmentItem.MeetingStatus will be 0 for Appointment items, while it will be non-zero for Meeting Items.
