Best practice advice from Microsoft is not to mix form regions and a legacy form on the same item. Is your form region using a replaceall region? What kind of weird behavior are you seeing?

Hi,

Using Outlook '07 and form regions, is it possible to force Outlook to use
the form region instead of the custom legacy form that sits on the personal
folder for the same message class?

Currently we do get some wierd behaviour when opening an item with a custom
message class that is associated with a form region and an old legacy form
that sits on the personal forms folder.
