    Opening (rather than saving) attachments in Outlook means it has to open

    *something*. Attachments are not files. They are merely long strings

    of encoded data within a MIME part in the body of your e-mail (that are

    presented as "attachments" in the UI for your e-mail client). The

    attachment is *in* your e-mail, not some file floating out in the ether

    that gets magically linked to the e-mail. Opening or saving the

    attachment means decoding that long string. For any program to *use*

    that attachment means to decode it and put it SOMEWHERE that the program

    can access. That means the attachment gets put into a file. If you

    open an attachment, Outlook decodes the attachment, saves it into a file

    within Outlook's secured temporary folder, and then passes the file to

    whatever is the handler designated for that filetype. When you exit the

    program that loaded the temporary file, and upon proper exit of Outlook,

    those temporary files are deleted. Any edits you made to them would be

    to the file created under Outlook's temporary folder. If you Save the

    attachment, Outlook decodes the attachment and puts that data into the

    specified file. It is then up to you to load whatever program you want

    to edit the file, and those edits will be saved to that file.

    If you Open the attachment (which means Outlook created a temporary

    file), and to see it outside of Outlook (and to whatever handler program

    Outlook passed the temporary file), enter the path for Outlook's secured

    temporary folder into the Address bar of Windows Explorer. To find the

    folder name, look in the registry under:


    where <version> is whatever version of Outlook that you installed; e.g.,

    10.0 for Office XP, 11.0 for Office 2003, and so on. The data item

    named "OutlookSecureTempFolder" points to Outlook's temporary file path.
