Appointments have been set as recurring appointments, but now when I go to delete, some appointments do not give the "Delete The Series? option. It should be noted also that the double arrows no longer show. I can delete them individually one-at-a-time only. I also use Goolge Sync, and these not deleting appts do not show on Google Calendar.

Are you on a BES and do you use Outlook for your normal calendar? Need a bit more info

I am having issues with a 9700 on BIS. BB calendar is sending the same appointment to google sync when syncing with google calendar.
