Mailbox full can't send any messages

Hi,
I was wondering if someone can tell me how I can delete individual emails please? I've found the place where you can clear out your whole inbox and sent mail but I don't want to do that just clear out a few older ones.

Thanks

Open the message you want to delete. Look below it and there is a delete this message option. Also by default all of your sent messages are saved. Click on that folder to see those and delete!

Thank you NBP! What wud we do without you ;)
