Difficulty: Moderately Challenging
Step1
First you must empty the messages in the folder you want to delete. Do this by opening the folder which contains the messages.
Step2
Place a check mark in the box to the left of the message you want to delete. Delete each message individually which will send them to the trash. To select all messages, just click the "check all" link at the bottom of the page.
Step3
Click "delete" to have all the messages you chose transferred into the trash bin (folder).
Step4
Do this over and over in each folder you wish to delete. You cannot delete a folder until you have emptied that folder of all the messages it held.
Step5
Once the folders are all emptied of messages, you are now ready to delete those folders. Click the "Folders" link on the left navigation bar.
Step6
On the "folders" screen, find the folders you would like to delete and click the "delete" link located to the right of the folder's name. The name of the folder will then disappear from the list of folders.
Step7
To permanently remove the contents of the trash, click the "empty" link next to the trash folder in the left navigation bar.
Step8
You will recieve a prompt asking if you are sure you want to delete all messages from the trash. Click "yes" to delete or "no" to return to the previous page. This gives you the opportunity to make sure you are not deleting anything you don't want to accidentally.
