Can't find the answer, but there are many unsolved threads. I have duplicate entries that are re-occuring events that were changed in Outlook via computer. They change, but show up twice on my DINC: same event, same time, same place, etc., but only once via PC. I am trying to solve and here's a question: when you go to calendar > menu > more > Calendars > what choices do you have and what do you have checked? I have "'My Calendar"; "Exchange"; and "PC Sync" and I feel like I should only have one checked, but don't knwo which one. I am new to Droid and want to stay, but this is killing me.
