When you mark an item on an IMAP e-mail server for deletion, the item is displayed in strikethrough text in the header list. However, the item is not removed from the IMAP mail server until a purge command is used.

 NOTE   You can change the view of an IMAP folder so that items marked for deletion do not appear. On theView menu, point to Current View, and then click Hide Messages Marked for Deletion. If you are using the Reading Pane, you must turn it back on after using this command. On the View menu, point to Reading Pane, and then click Right or Bottom.

If you do not purge the deleted items periodically, you might reach and exceed the allotted disk space on your e-mail server. If you exceed your allotted disk space, you might not receive any new messages, or you might incur additional charges from your Internet service provider (ISP).

Manually purge deleted items

To permanently delete the items marked for deletion, do the following:

1. Click a folder in your IMAP e-mail account.
2. On the Edit menu, point to Purge Deleted Messages.
3. Do one of the following:

• Click Purge Marked Items in “folder“.

Only items marked for deletion in the folder that you are in are purged from the IMAP mail server.

• Click Purge Marked Items in All Accounts.

 NOTE   You must be working online with the mail server for this feature to work.
