Has anyone experienced reoccurring entries with a reminder set not ringing/notifying all of the time? Are there any certain circumstances that would cause this? Would an old event scheduled on Outlook 2002 2-3 years ago with no end time be a problem or should I recreate it on the BB?

My unit is a 7520 with OS4.

I need to rely on this feature so any help would be appreciated.

Thanks!
