Summary:
When you tap snooze on an exchange calendar event notification the device puts a value of "-9 minutes and some seconds" in the advice field of the appointment. It causes stop syncing the calendar event because it sends to Exchange a malformed data value. I have extracted the value in the ActiveSync trace log and the malformed data corresponds to <Reminder xmlns="Calendar:">-9</Reminder>. It happens also with Google account but Google to workaround this behavior add a second advice to appointment, and this is not possbile for Exchange.

Steps to Reproduce:
1 add Exchange account
2 add an event to Exchange calendar and set advice at "at time of Event"
3 wait until the notify pop's up and tap on snooze
4 You will notice that in the event detail you will find an advice value of 9 minutes and some seconds
5 Drag it with finger to another hour
6 Access your Exchange account web page (OWA) and you will notice that the events remains in the old position
7 from now every changes to this appointment are not synced with Exchange except if you change the advice to a default value


Expected Results:
sync appointment after snooze

Actual Results:
doesn't sync appointment after snooze

Notes:
