Can anyone please help.

We have installed Office 2007 on some of our machines for evaluation, but wish
to continue using compatabilty mode (i.e. Office 2003) as documents are
regularly sent outside of the organisation for editing and return. These are
typically encrypted / password protected.

Whenever I save any changes to one of these in Excel 2007 I get

"This document is both encrypted and password protected. The Office Open XML
formats available in the 2007 release provide stronger encryption. Do you want
to increase the security og this document by converting to an Office Open XML

To which the answer is NO, not until I know that any recipients are also using
XML  formats.

How can I stop this message from appearing every time I save a protected
Just another confused user
