To export all current data to a .PST file using Outlook 2010, simply;

1, Select File, located on the top left
2, Open
3, Then import.

The import/export option will appear and these are unchanged from Outlook 2007.

As far as exporting profile data, this is not sometihng outlook can do. However, your local profile is stored on your local PC under start > control panel > mail > show profile.

Hope this helps
