Well, in the first place, this doesn’t appear to be a shield, and in the second place all we necessarily want to disable is the Outlook toolbar itself. That being said, we don’t have the Mail or Exchange shields running anyway.

Also, as I said earlier we’ve only seen it (or at least been asked about it) on a couple machines so far. And I believe they’ve both been running Outlook 2003, whereas most of the rest of the company is running Outlook 2007. Now, that’s not set in stone, however I know I have the Avast addin’s running in Outlook 2007 (I verified through COM Add-ins), but I don’t have the toolbar. Could just be a coincidence though. We haven’t really had enough reports of it yet to come to any hard conclusions. But since we use another anti-spam system (Postini) we don’t want to deal with a second.
