Is it possible to rename the title of a form in Microsoft Forms?
Even if you are using Microsoft Forms, or Microsoft Forms pro, you will note that the the Form Name is mainly associated to the Form Title and unfortunately, there is no settings to set the Form Name independently.
So based on what you will set in "Form Title" it will be automatically set as the "Form Name" as shown below', and in this case if ,you need to rename the Forms Name, the only option to do that is changing the Form Title first.
