Example

This example uses the Start property of the AppointmentItem object to determine if the appointment starts after normal business hours. If it does, and if the Sensitivity property of the AppointmentItem object is not already set to olPrivate, the example offers to mark the appointment as private.

Dim myOlApp As New Outlook.Application
Public WithEvents myOlItems As Outlook.Items

Public Sub Initialize_handler()
    Set myOlItems = myOlApp.GetNamespace("MAPI").GetDefaultFolder(olFolderCalendar).Items
End Sub

Private Sub myOlItems_ItemChange(ByVal Item As Object)
    If Format(Item.Start, "h") >= "17" And Item.Sensitivity <> olPrivate Then
        Prompt = "Appointment occurs after hours. Mark it private?"
        If MsgBox(Prompt, vbYesNo + vbQuestion) = vbYes Then
            Item.Sensitivity = olPrivate
            Item.Display
        End If
    End If
End Sub
