Here's a good example from the GetSharedDefaultFolder method section in the
Outlook VBA help file:
Sub ResolveName()
Dim myOlApp As Outlook.Application
Dim myNamespace As Outlook.NameSpace
Dim myRecipient As Outlook.Recipient
Dim CalendarFolder As Outlook.MAPIFolder
Set myOlApp = CreateObject("Outlook.Application")
Set myNamespace = myOlApp.GetNamespace("MAPI")
Set myRecipient = myNamespace.CreateRecipient("Dan Wilson")
myRecipient.Resolve
If myRecipient.Resolved Then
Call ShowCalendar(myNamespace, myRecipient)
End If
End Sub
Sub ShowCalendar(myNamespace, myRecipient)
Dim CalendarFolder As Outlook.MAPIFolder
Set CalendarFolder = _
myNamespace.GetSharedDefaultFolder _
(myRecipient, olFolderCalendar)
CalendarFolder.Display
End Sub
