We have a user who is using Outlook 2010 with Exchange 2010 SP 1. In his Outlook, tasks show up twice in the ToDo bar and also in his Tasks folder. If one instance of the task is deleted, so is the other. If the user is viewing his "home" screen in Outlook, the tasks DO NOT show up twice there. We have tried starting Outlook with the /cleanviews switch, and also tried the /resettodobar switch as well, but no luck. the issue also persists when creating a new Outlook and also new user profile.
Any ideas would be greatly appreciated
