About syncing personal content
With Nokia Ovi Suite you can sync personal content between your device and the data management software installed on your computer. This content includes your calendar and tasks items, notes, and bookmarks, and web feeds. For more information, see Modifying calendar and tasks sync options, Modifying notes sync options, and About syncing bookmarks and web feeds.
To avoid creating duplicate items, do not use other device applications, such as Mail for Exchange, for syncing your device’s personal content if you are already using Nokia Ovi Suite for this purpose.
