I have several channels in teams with each channel having guest users. When the guest users try and use Team Forms it asks them to login but it never logs them in, it just keeps going back to sign in. The only way they can use Team Forms is to open in a browser, sing in there, and choose the correct channel. They have the ability to choose any channel even though they are not assigned to that channel.
Is there a permissions setting that I am missing?
By default, channels in Microsoft Teams are available to all members of the team. The exception to this is private channels which is not currently supported by Team Froms.
In your scenario I would use one of the following options to give guest users restricted access to specific forms:
Create a separate team for external guests and house external form within that team
Generate a public link to your form and share that link with your guests
Add guess to your team but use SharePoint file permission to restrict which forms the user has access to.
As a side note when sharing forms with external users you should copy and share the link that include your tenant Id to avoid any login issue you mentioned. This can be copied following the steps below.
