Use Delete to remove selected items from your Mailbox.
You can also use Delete to retract items you have sent. You can retract mail and phone messages if the recipients have not read them or if they have not been sent to the Internet. You can retract appointments, reminder notes, and tasks at any time. For information on how to retract items you have sent, see Retracting Sent Email.
If you receive junk mail that requires frequent manual deletion, you might want to set up Junk Mail Handling. See Handling Unwanted Email (Spam) for more information.
To delete items from your mailbox:
In the Main Window, select one or more items, and then press the Delete key.
If you delete a sent item, the Delete Item dialog box displays. Select the appropriate Delete from option, and then click OK.
You can choose from the following options:
My Mailbox
Recipient’s Mailbox
All Mailboxes
If you delete a document reference from your Mailbox, only the reference is deleted. The document remains in the library.
Deleted items are moved to your Trash and remain there until the Trash is emptied.
