I noticed I get multiple alarms for calendar events on my N9. For some events, I get four times the same notification. I also sometimes get notifications for deleted events.

I sync my calendar over bluetooth. Since I had some troubles setting up the sync, I deleted the calendar a few times and synced again. So I have the impression that the alarms of the events of the deleted calendars are still stored in some database. I guess this causes the same alarm to be triggered multiple times and alarms for deleted events to be displayed.

Is there a way to re-generate the internal alarms database? 

(I did already upgrade to PR1.1, this didn’t fix it.)

I have the exact same problem and I am also using Bluetooth sync (with Windows 7 inbuilt Outlook sync in Nokia N9 Device Control Panel). I think the worst one has been 17 identical alarm notifications showing whent the calendar alarm fired. There are no multiple calendar events and all the duplicate alarms are dismissed simultaneously. This is very irritating. I am now running PR1.1, but the problem has persisted.

Another calendar problem has been, at least in PR1.0, having alarm notifications for some events  in UTC time not local time. The events were created originally in Outlook and synced to the phone over Bluetooth. The funny thing is that the events were at correct local time in the N9 calendar app, but the alarms were given in UTC time...

Same problem here. Also To-Do task are duplicated. Hope some improvements in next PR1.2

I had the same proble and the solution is to manually correct the calendar ( I know it could take hours) or change your phone (which I decided to do).  Moreover, since PC and N9 are syncronising in both directions you might have the same issue on your PC as well.

Could you please elaborate on how do you "manually correct the calendar"? Do you mean deleting the calendar event and re-entering it, or what? 

As I said, there is only one calendar event in the calendar, but it causes multiple simultaneous alarms. Please note that these duplicates are not shown in the calendar event alarm field. And since all the additional alarms are fired at the same time, they can be dismissed at the same time.

So far, the multiple alarms have not been sync'ed to PC and hence do not affect Outlook.

I used BT sync with Windows 7 (64 bit), because I was not able to do USB sync (as N9 is not supported by any Nokia PC sync soft). After that I had a real mess: Each event was multiplied to occur multiple times during a day, thoughout each week, throughour each year, e.g. for example meeting scheduled for 10am on October 20, 2011, occurred a number of times on the same day,  and each previous week until 2005 (when my calendar starts).  An event that was scheduled back in 2005 occurred each week throughout 2011.  The same thing happened to my Outlook. So you can imagine a mess that I got with my calendar after syncing with N9. Thanks that I had intact calendar on my Ipad and was able to restore my Outlook.  I had to to manually correct calendar on N9 (because any further attempts to sync with Outlook) resulted in the same mess.  When I say manually I mean that I deleted all entries (takes time) and re-entered only ones that I really needed (such as birthdays, other anniversaries and meetings from October 2011 forward).  After that I did not risk syncing N9 with Outlook anymore in expectation of a decent  sync software from Nokia (which I doubt will come, since even their latest soft Nokia Suite is not supporting N9 (although there some users were able to successfully sync with PC Suite, and some installed previous version of Ovi Suite, upgraded it to Nokia Suite and it works now for them -- but not for my very special N9).  Having fianlly lost confidence in Noikia I decided to become a happy user of iPhone (with all or at least most soft needed being put in place by Apple or 3rd parties).
