Forms Quick Poll doesn't work for guest users
Hi, this feature is not yet supported. There is a Teams User Voice requesting this which you can add your vote to here - https://microsoftteams.uservoice.com/forums/599053-schools-and-universities/suggestions/40343389-allow-guest-users-students-to-access-quiz-forms
Guest permissions by definition are a lot more limited than full users in Teams. Take a look at https://docs.microsoft.com/en-us/MicrosoftTeams/guest-experience#comparison-of-team-member-and-guest-capabilities for further information.
Thanks for your quick response! I will upvote the User Voice, although the issue is not exactly the same as mine (it talks about Quiz Assignments).
I have read the article on guest permissions many times, since I work for a foundation that supports a national network of educational institutes and all our Teams consist mainly of guests working at those institutes. I am well aware of the general limitations of the guest user experience. The list of capabilities of members and guests on that page tells me that guests cannot 'Add apps (tabs, bots, or connectors)'. As far as my logic goes, this doesn't tell me that they cannot interact with a poll added by a member/owner (i.e.: me). It's also not universal logic that 'can't add' also means 'can't interact', because they can interact with tabs I've added, for example.
We're very active in finding ways to use Teams to keep the collaboration in the network going in these times where our board, committees and project groups can't meet each other in real life. This not being able to logically infer what works for our Teams with guests and what not is increasingly frustrating. I get referred to the 'Guest experience' support page a lot, but in my experience, the devil is often in the details not mentioned there.
Naturally, this is no criticism on your kind response. But if you, or anyone else, can guide me to more details about what works and what not for Teams with guests, I would be very grateful.
I agree, there is nothing on that page that specifically says that it won't work, which is confusing. Teams is a constantly evolving product though so we just have to wait for some features to be added sometimes. 
I agree, and I also understand that these are challenging times for the Teams development team, since the needs and demands have risen and changed greatly over the past months. My main problem is not with functions not working for guests (although I'd prefer if they would;)), but in not finding clear descriptions of that and having to find out the hard way repeatedly. But that's not what this community is for, I'll probably have to get that to Microsoft via UserVoice.
Thanks again!
