Blackberry Z10 Calendar Notifications
 

My Z10 is setup to sync via Active Sync with Exchange 2010.

My calendar on Z10 synchronizes with no issue and each meeting syncs reminder notification time with Exchange.

Typically I receive proper calendar notification at time set for calendar reminder.

I then view the calendar entry and dismiss.

I then get another reminder at the time of the meeting.

How do I disable the reminder at the time of meeting after I have already acted on the notification? I can see if I snooze the reminder or ignore it that I would get reminded again, but I should not get reminded of something I have dismissed.

Thanks
