I am no longer able to switch between profiles in Outlook 2007. It will also not close down properly unless I end task in task manager. I think the 2 problems are related from what I have found on the internet. I have installed all the latest patches and service packs and started to disable the add ons. The only one that will not let me disable is Outlook Change Notifier which i think is part of apple. It locks my outlook up when I try to disable it.
