Instead of using the syntax in the following
example
Set oActExp = Application.ActiveExplorer
Set MyCB = oActExp.CommandBars(1)
use the syntax in one of the following methods.
Method 1: Use the Item Method to Return the Member
Set oActExp = Application.ActiveExplorer
Set MyCB = oActExp.CommandBars.Item(1)
Method 2: Strongly Type the Explorer Object
Dim oActExp As Outlook.Explorer
Set oActExp = Application.ActiveExplorer
Set MyCB = oActExp.CommandBars(1)
Method 3: Do Not Use a Variable for the Explorer Object
Set MyCB = Application.ActiveExplorer.CommandBars(1)
