To resolve this issue, re-establish the reference to the button before each use. To do this, use the following macro:
Public Sub DoTest()
Dim cb As Office.CommandBar
On Error Resume Next
Set cb = Application.CommandBars("Context Switch Test")
cb.Delete
Set cb = Nothing
On Error GoTo 0
Set cb = Application.CommandBars.Add("Context Switch Test")
cb.Visible = True
Dim cbc As Office.CommandBarControl
Set cbc = cb.Controls.Add(msoControlButton)
cbc.Tag = "xxx"
cbc.Caption = "Hi There"
Application.CommandBars("Context Switch Test").Controls(1).Tag = "xxx"
MsgBox (Application.CommandBars("Context Switch Test").Controls(1).Tag)
MsgBox cbc.Caption
End Sub
