I've just uninstalled the Office 2007 trial and installed a retail copy of
Outlook 2007. For reasons I won't go into I've reverted to Office 2000,
with the exception of Outlook, which didn't work with Vista.

While the Outlook editor still autocorrects spelling mistakes, I noticed it
isn't underlining unknown words in red any more. When I go into the Editor
Options and select Proofing, all the options in the Microsoft Office Section
are available to me, but the Outlook specific ones are all greyed out.
Moreover, in neither of these sections is there a "Hide spelling errors"
checkbox, despite the Help file telling me it should be there.

Ideas, anyone?
