I would like to transfer all my contact details from office outlook 2003 to office outlook 2007 contacts?

You export/ import under file menu. choose export to file, click next and choose excel or tab or comma delimited file, click next and choose your contact folder and save the file to your chosen location.


Repeat this action in outlook 2007 - only on the first step choose import addresses and email and select the file you created in the first step.
