Color Label for Calendar Items

Since Outlook XP appointments can be labeled - but not via the Outlook object model. The sample shows how to use the Redemption for that. You cannot choose colors of your own. Instead, values from 0 (no label) to 10 (telephon call) are possible, and Outlook then assigns the determined color itself.

Private Sub LabelAppointment(Appt As Outlook.AppointmentItem, _
  Color As Long _
)
  Dim Session As Redemption.RDOSession
  Dim rdAppt As Redemption.RDOAppointmentItem
  Dim EntryID As String
  Dim StoreID As String
  Dim ID As Variant
  Const PropSetID1 = "{00062002-0000-0000-C000-000000000046}"
  Const PR_APPT_COLORS = &H8214

  If Len(Appt.EntryID) = 0 Then
    Exit Sub
  End If

  Set Session = CreateObject("Redemption.RDOSession")
  Session.LogOn

  With Appt
    EntryID = .EntryID
    StoreID = .Parent.StoreID
  End With

  Set rdAppt = Session.GetMessageFromID(EntryID, StoreID)

  ID = rdAppt.GetIDsFromNames(PropSetID1, PR_APPT_COLORS)
  ID = ID Or &H3

  rdAppt.Fields(ID) = Color
  rdAppt.Save

  Session.Logoff
End Sub
