As Outlook is the program that is designed for you to keep your emails and attatchments organised for as long as you need , Even for years and to allow for sarching and reference, I cannot see the need to save in your documents so I am going to opt out and see if another expert can help you.
Here is a smart way to save your email messages from Outlook to the hard drive or any other drive.
First create a new folder on your desktop, then close all open windows and application. Next open Outlook and resize and move Outlook window so that the new folder on your desktop is visible in the background. Now in Outlook open the email folder that you want to copy the messages from (e.g. Inbox), select the messages and simply drag them to the new folder on the desktop, When you finish go to that folder and copy it to another drive or location.
Hope this helps. Let me know if you have any questions.
The only 'standard' editable format you can save outlook messages to is txt format. However, that can be done for each message separately, or for multiple messages but into a single txt file. To save messages into txt file select the message in the message window or from the message listing and click File > Save As then choose Text Only (*,txt) from the 'Save as type' drop down menu.
