Dim mapiNS As Microsoft.Office.Interop.Outlook.NameSpace = olApp.GetNamespace("MAPI")
Dim profile As String = ""
mapiNS.Logon(profile, Nothing, Nothing, Nothing)
Dim apt As Microsoft.Office.Interop.Outlook._AppointmentItem = DirectCast(olApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem), Microsoft.Office.Interop.Outlook._AppointmentItem)
apt.Subject = ddItineraryItems.SelectedItem.Text
apt.Body = txtPItinerary_Desc.Text
apt.Start = CDate(txtDateFromPopup.Text)

If you are going to use Outlook by Interop, then you would need to install it on your server. Without installed Outlook - it won't work.
PS. Your code will work only with Outlook account that is configured by default. And it will work only if you are using external service for appointments. Otherwise it will save that appointment just to Outlook on server, without updating it to your local Outlook
And using Interop in web applications on server side isn't a good idea, as it will starts new Outlook process every time, that is very resource expensive. Better way is to integrate with Calendar system that you are using, like Google Calendar, etc.
