I use Office 365 and all of a sudden I can't open Outlook. When I click on it, the circle spins and then stops. I have tried all of the online answers and nothing has worked. Outlook has also disappeared from the Task Manager Process tab, but does show up under the Details tab as OUTLOOK.EXE and is disabled.
Outlook is still in my Start list.
This does not seem like a complex problem to me, yet I can't fix it.
