Ejecutar una macro cuando se abre Outlook

An Outlook Visual Basic for Applications (VBA) macro can use this event procedure to initialize itself when Outlook starts.

Example
This Microsoft Outlook Visual Basic for Applications example displays a welcome message to the user and maximizes the Outlook explorer window when Outlook starts.
Private Sub Application_Startup()
    MsgBox "Welcome, " & Application.GetNamespace("MAPI").CurrentUser
    Application.ActiveExplorer.WindowState = olMaximized
End Sub

1. Launch Outlook.
2. Set your security to Medium or Low (sounds like you did.)
3. Press Alt + F11 on your keyboard
4. If you do not see a module when the Visual Basic editor launches:
    *Expand the folder labeled Microsoft Outlook Objects in the Project Explorer Window.
    *Double click ThisOutlookSession
5. If the module is blank:
    *click the Object dropdown at the top of the module window (it reads General)
    *Select Application
    *Select Startup from the Procedure dropdown (it reads Item Send)
You should now have a code window like this:

CODE

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
End Sub
_____________________________________________________________________
Private Sub Application_Startup()
End Sub

Write your code in the Application_Startup() routine.
