Forms built within a team are automatically available to members of your team. Forms can also be shared with people outside of your organisation without any additional licensing. The external users can be a personal Microsoft account (e.g. collaborator@gmail.com) or Work/School account (e.g. user@company.com) or completely anonymous.
To share your forms externally you can either use the following steps to invite the user as a guest to your team or generate a public link to your form:
Invite the external user into your team using Microsoft Teams as shown below
Install Team Forms as a channel app in the team or send the user a link to Team Forms that is specific to your organisation's tenant.
Once the external user accepted your invitation to the team they can easily access your forms by following the link in the email sent by Microsoft or by logging into Microsoft Teams, selecting your organisation and navigating to the Team Forms channel app. Alternatively, your external user may access Team Forms in the browser using the multi-account feature.
