I have messages in my webmail from 2011!! How can I delete them without deleting one at a time??
You must have quite a lot of old emails there! There is the option of selecting all of the displayed messages (on the page) by clicking the check box at the top, right below the "New" button. That should be faster than deleting each message individually.
Shift-Click that box, to select all messages, in the folder, including ones that haven't been loaded yet
