The tablet part is tough.


If your form is using macros, it will not work on a tablet.


I don't know that legacy form controls work on tablets; my understanding is that content controls do not.


The term "form" in Word is disappointingly ambiguous.
What, exactly, are you doing to make it a form? Protecting for Filling in Forms?


What kind of controls are you inserting?

Legacy form controls?
Active X controls?
Content controls?
