Microsoft Outlook automatically saves all unfinished messages for you. By default, unfinished messages are saved to your Drafts folder every three minutes. You can, however, change this time interval or location. You can also save a message as a file or as a template.

How?
Do one of the following:
Turn Word on or off as your default e-mail editor for all new
messages
Turn Word on as your e-mail editor for one new message
Turn Word on for viewing all
Outlook Rich Text formatted messages
You may want to set this option if you often receive the message "This message contains formatting that is best viewed with Microsoft Word. Click here to display in Word."
Note If Word is your e-mail editor, see Word Help for information about working with messages.
