importing/exporting address books

[Kiriray]

Hi,

Is there a way to export Outlook contacts list in a way wherein we could still keep the groupings in the address book? A client of ours wants to use Outlook Express as he's having problems with Outlook when he's sending to multiple users.But the problem is the contacts list. I know how we could import the contact list to the OE address book, but i don't know if i can do it at the same time saving the current grouping of the OUtlook contact list. That's his main concern and he does not awnt to spend time grouping the individual contacts.

Any suggestions?

Thanks!
