When Synchronizing my BB with Desktop Manager it is only syncing the past 14 days and all upcoming events/appointments. This is somewhat ok however it is deleting all past events/appointments on my Outlook Calendar that occur prior to the 14 days. I have set the sync to sync all scheduled items in the Microsoft Outlook Options for calendar but it keeps deleting any events/appointments prior to 14 days of current date.

Any suggestions as to what I need to change in order for events/appointments to not be deleted from Outlook Calendar?
