Starting just this week my Office Reminders app is not working properly. Randomly throughout the day it pops up and bounces in my dock for about half a minute. Then a reminder (though I do not have one set for any of these times) quickly flashes, then the whole app shuts down again. Same thing happens if I try to open the app manually. I've deleted the com.microsoft.outlook.office_reminders.plist, but that did not fix it.
