When I set a repeating event (ev at 17:00) and then I set a reminder to email me 10 minutes before the event.
The reminder is never sent.
In addition, the next day the repeating event is gone.
Please tell me - did you type "ev at 17:00" within the task name? If so - that's not a valid due date format. Please use "ev day at 17:00" if the task should recur every day. Also, to set a recurring reminder, please right-click on the task, choose "Reminders" select "Absolute reminder" from the drop-down menu and set the reminder to "ev day at 16:50".
I'll make sure that I have configured it that way - Thanks
