Has anyone noticed slow Outlook 2007 performance after recent Windows Updates or Kaspersky update?  Some users are saying Outlook is running slow.  One user with a high performance new computer reported that it's slow overall and it can take 10 seconds to dismiss a calendar reminder.  So far it has only been users at branch offices so it may just be a WAN issue (it's pretty saturated) but I wouldn't think slow WAN would cause such a delay in dismissing a calendar reminder.  It has also only been Windows 7 users but I don't know if that's relevant at this point.
