By default, OfficeTalk will keep a sent mail record for each recipient that you send mail to. You may disable sent mail in the following way:
Select Preferences from the Options menu. The Preferences dialog box is displayed. Select the Send page.
Uncheck the Save a copy of sent messages in the Sent Mail folder check box. Press OK to save your changes. The next time you send a mail message, OfficeTalk will no longer save a copy of the message in the Sent Mail folder.
