This Microsoft Visual Basic/Visual Basic for Applications example adds a group named Marketing as the second group in the Outlook Bar.
Dim myOlApp As New Outlook.Application
Dim myolBar As Outlook.OutlookBarPane
Set myolBar = myOlApp.ActiveExplorer.Panes.Item("OutlookBar")
myolBar.Contents.Groups.Add "Marketing", 2
If you use VBScript, you do not create the Application object. This example shows how to perform the same task using VBScript.
Set myolBar = Application.ActiveExplorer.Panes.Item("OutlookBar")
myolBar.Contents.Groups.Add "Marketing", 2
