Q. How do I select all messages in webmail and delete them or move them?
In your e-mail account, select the inbox then at the bottom you are going to see a box with a green check mark at the bottom. Click that, go to the bottom and select trash then click move (click on individual e-mail boxes to select a couple that you might now want to delete). Then remember that when you move it to the trash it is still there it will still take up space until you delete trash.
