You ICT Geniuses - How Do I...?

I realise this might be a stupid question, and I have looked and it has been asked many-a-time but there are no answers. I have over 27,200 emails in my hotmail box, I've had the account since 2007 so this is probably why there are so many emails ! Hense why I don't want to do the 'Select All' and delete, I actually want to delete the whole 27,200 without doing it by-hand by clicking a delete button repetitively. Help please?
