You can usually right click, save as to a desired location. Attachements are usually pdf or zipped format, most other file formats are blocked to save guard your system by outlook to unblock is not wise. If you get a message from outtlok saying it blocked your attachment on a txt message then tell the sender to put it into a zip format. If you don't see a icon for the attachment then you don't have a program to open it you will see a Windows icon on a little white background. If you see a compression icon just double click on it to open (Win XP) have zip built in.
