Could someone please tell me how to sync my bb calendar with my Outlook calendar without deleting the things that have occurred in the past? I have tried every setting I can think of. I used the date range option, the one-way sync, and two-way sync. Please let me know what I am missing. I appreciate any help you can provide.
You should be able to use you blackberry desktop manager. Here is an explanation of how to use it for your device. I do not know if it will delete past entries.
There are settings with the BlackBerry Desktop Manager that will allow you to do this. You can sync either ALL events or just current and future. The same with tasks (all or just current and future)
