Conversion of txt files to pst file format

You can save a new email message in Outlook and copy and paste the content of your .txt file to the body of the email and save it. This will make a copy inside your .pst file and essentially achieve txt to pst conversion for you. But it is likely that you can also find some utility that allows you to convert txt to pst directly, for example MSG 2 PST.
