First the gratis option: As you probably know, it’s easy to save an Outlook e-mail message as text. Just open the message and click on File and Save A s. You then have the option to save it with a file name and a format—as HTML or plain text; if you want, you later can convert either version of text to a Word file, but that’s an extra step.
Now, what you probably didn’t know is that you can save a bunch of e-mails as a single file. So if you have a group of e-mails relating to one subject, you can store them in a single message. To do that, select the e-mails you want to gather together and, while holding down the Ctrl key, highlight them one at a time and then click on File, Save As .
This method provides a bonus. Compared with trying to search through Outlook’s native database, you’ll find it easy to index and search those more familiar text files.
If you’re willing to pay for a utility, called ArchivER, that does the above and much, much more, go to http://www.smtechnologies.com/prod13.htm and download a free evaluation copy. The program can migrate Outlook data into individual files and directories using a common file format rather than the Outlook archive folder.
