I have a problem with Outlook 2010 objects (messages, appointments, tasks) defaulting to the first tab rather than the second. For example in an appointment, the first tab is "File", but it is "Appointment" that contains the most used menu items. What's worse, every time I edit the appointment it reverts back to "File" after *each* edit is applied. I have been using Outlook for many years and this just started a couple weeks ago. I don't have time for this, not to mention my aching shoulder. Can you help?
