Hello mikl76,
Download this Outlook/nokea sync
It converts name fields such that you can find contacts by the “File As” field on your phone. It also performs phone number processing, converting alphas to numbers, commas to pauses (p), and eXtension specifiers to waits (w). The conversion takes place while copying the contacts over to a “Nokia Contacts” folder (path is “Personal Folders\Contacts\Nokia Contacts”). You can then configure Nokia PC Sync to synchronize your contacts out of this folder.
