Thanks, that info is great, but I still want to know how to delete more than 50 at a time. Anyone know?
Editted to say, never mind....I figured it out. When you get to your PM boxes, scroll down to Edit Folders on the left hand side.
When you click on that.....your folders will show on the right side. Click on "Sent messages", then "Empty folder", then "Yes" to delete permanently. Do the same for your Inbox. Be sure to download all as text into Notepad if you want to keep the information though.
