Microsoft Forms is a service within Microsoft 365 for building surveys, quizzes, polls, and other forms and gathering responses online. This link points to a response page on forms.office.com, the address used when someone opens or submits a form created with the service. Such pages typically display the form's questions or a confirmation after submission, and they may require signing in or may no longer be available depending on the form's settings. The page itself returned only a loading message, so its specific contents could not be determined.
