Delete all contacts and import clean address book

I agree with others that managing Contacts is very poor in Microsoft products.

An address book is one of the most important elements yet should be the simplest to manage.

I have ended up with duplicates, triplicates etc and retrieved email addresses and the "3 at a time" merging is a nightmare.

I exported contacts as a csv to Excel and with a few formulae combined or deleted them quickly and easily.

Now, can I empty my Contacts and import this CSV?

I cannot see where to delete all contacts. There must be a way to do this surely?!

Anyone any ideas?

Cheers
