How do I stop this message from popping up?

[Ants-64]

I keep getting a message when I close Outlook Express 6, saying that it can compact messages to save disk space. First of all, it does it even when I delete the deleted emails manually. Second, I just don't want to see this message ever again in my life. So my question is: Is there a way to stop this madness? Thanks, Anthony

I use Outlook 2010 so it's probably different but, open your Outlook Express and look for Options then Settings, or Advanced Settings. From there your looking for AutoArchive. Maybe someone else uses Outlook Express 6.
