Edit attachment and return from RWW

I'd like to open an attached .xlxs, .xls or a .docx, .doc, etc. from Remote
Web Workplace (RWW), and send it back without having to save it to my desktop
or my PC and add attachment.

I am aware I can open the above using straight OutLook, edit it, and send
it back exactly as I want. But, that is not RWW.

However from RWW, all or most all attachments come in as "read only" EVEN
though they ARE NOT sent as read only.

SO: From RWW, open an attachment edit it and sent it back without having to
BROWSE for a saved file.

MY guess this is a problem area built into RWW and OutLook, but Just maybe,
you MVP's have an easy way.

The hard way is to open it, adjust it, save it, and then resend and attach
the edited version. I'd rather do it direct.

How many times did I repeat my self for clarity.

Any help woud be greatly appreciated.

Thanks

Mark
