¡Resuelto!

En lugar de:

AppActivate Application.Caption

Este:

SendKeys "% i"

Entonces:

Option Explicit
Sub Test()
    Dim Outlook As Object
    Set Outlook = CreateOutlook()
    Set Outlook = Nothing
End Sub
Function CreateOutlook() As Object
    Dim Minimize As Boolean
    Dim Outlook As Object
    Minimize = False
    On Error Resume Next
        Set Outlook = GetObject(, "Outlook.Application")
    On Error GoTo 0
    If Outlook Is Nothing Then
        Shell "Outlook"
        Minimize = True
    End If
    On Error Resume Next
        Do While Outlook Is Nothing
            Set Outlook = GetObject(, "Outlook.Application")
        Loop
    On Error GoTo 0
    If Minimize Then SendKeys "% i"
    Set Outlook = Nothing
    Set CreateOutlook = CreateObject("Outlook.Application")
End Function
