The system folders are Inbox, Sent, Drafts, Junk, and Trash. You cannot move, rename, or delete these folders. System folders are always displayed at the top of your folder list in the Mail Overview pane, followed by any folders you create.
New mail arrives in the Inbox. By default, your Inbox is displayed after you log in.
A copy of each message you send is saved in the Sent folder.
Messages you have composed but have not sent can be saved in the Drafts folder. If you open a message in the Drafts folder, it opens in the Compose view.
Most filtering of unsolicited automated mail (aka "spam" or "junk mail") is handled by a spam filter before those mail messages reach your Inbox. Mail that might possibly be junk mail, but isn't certain to be junk, may be placed in your Junk folder. You can review these messages and either move them or delete them. If you don't delete them, they will be purged after a period of time as specified by your email administrator.
Note: If you find that you are receiving a large number of unwanted mail messages, contact your email system administrator. Reporting mail as spam helps your mail administrator to fine-tune any spam filtering that may be in use at your site.
If you find a message that is clearly not relevant, you can select the message and in the More Action box select Spam.
Deleted items are placed in the Trash folder and remain there until you manually empty the trash or until the folder is purged automatically. ail is purged from this folder after a specified period of time, as specified by your administrator.
