How do I collaborate with a colleague on a Microsoft Form?

Work with a colleague to edit and view entries together submitted in Microsoft Forms

Warning: Collaborators don't get email notifications when form entries are submitted. See:

Note: Instead of using the Share to Collaborate option as described in the video below, another option is to change your form ownership to a group. See:
