Before you can delete emails, you have to be in the main window of the Web Mail client in the email folder you where the messages are located that you want to delete. Next, put a checkmark in the lines before the emails you want to delete. Once you have selected the emails you want to delete, simply click on the "Delete" button. All the emails you have selected are now automatically copied into the "Trash" email folder. Once you delete the messages from that folder, they are permanently erased from the system.
