| | BlackBerry Sync Deletes iCal events: Solution
I noticed that my Blackberry erases anything in my calendar that is older than 60 days. IT SOMETIMES TRIES TO DO THIS EVEN WHEN I HAVE ALREADY TOLD THE BLACKBERRY TO KEEP APPOINTMENTS FOREVER.
IF WHEN TRYING TO SYNC YOU GET: "Sync Alert: Syncing with BlackBerry desktop Manager will change more than 25% of your calendars, events, or to dos on this computer and then it shows you that it is about to delete a large amount of calendar events. STOP. Click on Sync Later.
Then do two things:
1) Make sure the BlackBerry is set to keep appointments forever
Go to the Calendar in your blackberry and opening it and then hitting the blackberry option key and scrolling down to Options and selecting Options
then select General Options
Then scroll down under Actions and find Keep Appointments and set this to Forever
Then hit the back key (the curved arrow to the right of the track ball) and select save
2) On your Mac:
Quit BlackBerry Desktop Manager and
Navigate to <User>/Library/Application Support/
Delete the BlackBerryDesktop folder.
Empty the Trash Bin.
Restart BlackBerry Desktop Manager.
Change all your syncing settings and Sync. It will alert you that this is your first Sync ever. Choose Merge data for each choice when it asks.
