Outlook 2007 Dictionary is the Sender's Language

A co-worker changed her regional language settings in XP to French.
Now when I reply to her emails, all of the words come up underlined.
It will not allow me to change the language settings in the message
back to English. I change it but the settings don't stick, even if I
select "Default". Is there a way to ensure that my settings are
always English?

We have found exactly the same issue during a corporate migration to Office
2007. After consulting with MS directly, there were conflicting view that
this was either behaviour by design and a fundamental flaw. In any case,
there is a 'fix' being developed for this as part of the next Service Pack
(2). Not sure when this is being released though.

As a workaround, this doesn't appear to happen in the mail is set to Plain
Text (presumably because Word isn't being used as the editor). Also, this is
not solved by disabling the Detect Language Automatically option...
