This Visual Basic for Applications example adds a new folder to the default Contacts folder, and then uses the MoveTo method to move it to the default Inbox folder.
Set myOlApp = CreateObject("Outlook.Application")
Set myNameSpace = myOlApp.GetNameSpace("MAPI")
Set myFolder = myNameSpace.GetDefaultFolder(olFolderContacts)
Set myNewFolder = myFolder.Folders.Add("My Contacts")
myNewFolder.MoveTo myNameSpace.GetDefaultFolder(olFolderInbox)
If you use VBScript, you do not create the Application object, and you cannot use named constants. This example shows how to perform the same task using VBScript.
Set myNameSpace = Application.GetNameSpace("MAPI")
Set myFolder = myNameSpace.GetDefaultFolder(10)
Set myNewFolder = myFolder.Folders.Add("My Contacts")
myNewFolder.MoveTo myNameSpace.GetDefaultFolder(6)
