After the installation of the Microsoft Office Beta 2 TR there was a change
in the UI of the Message Form of Outlook 2007. The Send and Account buttons
are taken away from the Ribbon and placed next to the To… and Cc… buttons.
When having open this Compose Message Form and press the Design This Form
button the design UI will appear. However, the Send button is gone and does
not appear with the rest of the controls in the design pane. If no changes
are made at this point and you run the form, the Send button (along with the
Account  button) does appear again, however, if you do any change before
running the form the Send  and the Account buttons will not appear. In
general, what you see in the design form is not what you see in the end
running form.

My aim is to just add a few extra controls to the existing Message Form but
in the design mode I don’t get the expected result.

Is this a known issue, any suggestions are welcome.
