I'm having a very strange problem on a Blackberry Bold 9900 I'm in charge of:
I've got 2,800 calendar entries, I'm syncing the BB via USB with Outlook so once per week. And there it goes: the BB suddenly deletes entries on the device and wants to do the same on Outlook.
Of course I've set 'keep appointments' to 'forever' and I'm syncing only one calendar in Outlook.
It seems that the BB only deletes appointments older than 30 or 60 days and keeps latest, future and reoccurring ones.
I've tried everything I've found on Google to solve this, but nothing helped so far: Deleting whole BB, deleting only entries and do a one-way-sync. I even changed the device but within one week my BB still deletes entries.
Since the new update for Desktop Manager I thought it could fix my calendar problem as it doesn't ask Outlook to delete anything but a week later it tried the same.
Actually I'm speechless now and I don't know what to do on this. It bothered me and my colleague for years as it can occur a week or months after a wipe - but it will. Is there any cure for this kind of demon?
