We can suggest to have a look at following solution:

1) Synchronize your IPaq phonebook, to-do list and calendar with MS Outlook
using Active Sync.
2) Import phonebook, calendar and To-Do list data from MS Outlook to Nokia
6600 using Oxygen Phone Manager II for Symbian OS phones (
http://www.opm-2.com/symbian/ ).

You can download the latest trial version here:

If you have any questions and/or suggestions, concerning our
program, feel free to post them on our official forum
