    Delete obsolete or unnecessary copies of sent mail from your Sent Items folder

    When you send a message, a copy of that message, including any attachment, is saved in your Sent Items folder. If you need to keep messages in your Sent Items folder for archive reasons, consider using Personal Folders to organize these messages. Instructions on how to setup and use Personal Folders are below. To disable the automatic saving of sent mail, select Tools/Options from the menu, select the Preferences tab and click the Email Options button. Deselect the option Save copies of messages in Sent Items folder and click OK, then click OK again.

    Delete obsolete or unnecessary email from your Inbox and other folders

    While viewing messages, you can click on the Date column header to sort your mail in ascending or descending order by the date it was received. You can also click on the Size column header to view messages largest to smallest. This allows you to view and remove larger emails, which take up most of the space in your mailbox. If you need to keep messages for archive reasons, consider using Personal Folders for this purpose. Simple instructions on how to setup and use Personal Folders are below.

    Remove large attachments from your Inbox and/or Sent Items folder

    While viewing messages in any folder, you can click on the Size column header, or the column header with the paper-clip, to view large messages or those containing attachments in ascending or descending order. Removing messages with large attachments greatly reduces the size of your mailbox.
