A synchronisation conflict occurs when you change the same email or organiser data item on your BlackBerry® device and in the email application on your computer.

If you reconcile your email using wireless email reconciliation, on your device, you can set whether the email on your device or the email on your computer takes precedence when an email reconciliation conflict occurs.

If you synchronise your organiser data using wireless data synchronisation, the organiser data on your computer takes precedence over the organiser data on your device when a data synchronisation conflict occurs.

Research In Motion recommends that you regularly create and save a back-up file on your computer, especially before you update any software. Maintaining an up-to-date back-up file on your computer might allow you to recover device data if your device is lost, stolen or corrupted by an unforeseen issue.
