Sounds like someone monkeyed with the Windows registry. Look in HKCU\Software\Microsoft\Office\11.0\Outlook\Custom Forms to see if a substitute for the IPM.Post or IPM.Note (which is the message class for messages, not IPM.Post) form has been deleted and remove it as necessary.

We had created a custom contact form a few months ago in Outlook 2003.
Yesterday, one of our users' Email Inbox messages were all converted to the
custom contact form and no longer use the Default Email form (which is the
form we need to use). When a new message comes into the Inbox, it is a
normal Email message at first, but then converts to the custom Contact form,
with the email message appearing within the Notes section.
The user is unable to Reply to or forward email messages, making business
very difficult.
We understand that the message class may somehow be incorrect on the Inbox,
but are unable to find a solution to fix it. The message class is still
listed as IPM.Post.

Please help us correct this issue. Any help is much appreciated!
