Change msg classes displaying form region (VS2010, Outlook Addin)

Is it possible to change the answe开发者_C百科r to this once the region has been created?

Yes, and you will have to re-register a new form region if you have any.

reg.Create(HKEY_CURRENT_USER, _T("Software\\Microsoft\\Office\\Outlook\\FormRegions"))

for an example.
