this is a feature I have used in Outlook 2003 (or earlier version, am not
sure) without a hitch, but do not know how to implement in 2007.

when I got a mail with attachment (say Word), I would normally double click
on the attachment to open it, edit or review and then close the attachment.
when i save the email the edited/reviewed attachment used to get saved. I
would then send it back to the sender, who now received the reviewed
document. This way, I could save myself the trouble of storing reviewing and
re-attaching the documents. This worked very well, when I did not have to
store those documents. I knew it was not a security-proof feature, but what
the heck ?

Now, when I open an attachment in 2007, it always opnes in "Read-Only" mode
and that forces me to revert to a method (of saving, reviewing and
reattaching) that I do not like.

Is there a method available in 2007 similar to what I am used to (explained
above)?

thanks for your comments/help.
