I observed the same here. If I start Evolution after reboot, no exchange pop-ups appear. After unchecking and rechecking my exchange calendar in Edit->Preferences->Calendars and Tasks->Alarms, the pop-ups appear. However this is not of persistent nature. After the next reboot by default no exchange pop-ups appear as long as I do not uncheck and recheck my exchange calender again.
So we make progress... but the current solution is still annoying.
