I used to use outlook express. There is a lovely function to insert text
file's text into my currently writing email. How can I do that in my outlook
2007 ?

Time before, I first create a text file, say 'payment method.txt', then type
in all my standard payment method information to my customer. When I was
replying an email with my standard text, I simply use the "insert - text
file" function, instead of openning the 'payment method.txt', copy and paste
to my email.

Can I do that similar in outlook 2007 ? Thank you very much
