Quiz within Teams/Assignments can not be opened from a guest user. A user within the organisation can open the quiz. If this would work for the quests as well would be nice.

Ticket for the investigation: 16157244

Our tenant requires MFA, even for Guests invited to Teams and Azure.
The guest registers and approves the sign-in on the phone, and then gets a question if I want "my organization to manage my device".
If the user click anything except "No, I only want to login to this app", there is an error message thrown back saying there was a JSON syntax error with error code CAA60007. This error should be better managed in the B2B API.

This has started recently in the last two weeks or so. As a guest of a tenant, I can no longer see GIFs previewed in chat. There is a discussion of this on the Tech Community forum here:

This issue only seems to affect the web and desktop clients. It is not an issue on the Android or iOS apps.

We've tested many times and many ways.
The Guest User cannot give control of their screen when they doing Screen Sharing in chat.
The workaround is we can schedule a Teams meeting but it will be more handy if this functionality can be added in the chat!!!
Please remove some restriction on Guest User when they are using the main features about Teams!!!
Thanks a lot in advance!

We have been using the raise hand for guests, this week it is gone in the Windows Client, Android and IOS. Guests can only raise hand in the Web client, is this by design or is it a bug.

Setting to OFF option "Members can invite" in Azure Active Directory > Users > User settings > External users > Manage external collaboration settings disables ALSO admin members from inviting guests, not only non-admin members as declared.
So, this an "block all / allow all" option and there is no simple way to prevent standard members (non-admin) to invite guests.

As side effect it produce the infamous "We didn't find a match" message in the search box when you try to add a guest, mentioned by a lot of users.

Please, fix it !!!

unable to add people from outside the org to team or invite to a meeting. It says "we didn't find a match" and add button is grayed out.

When I switch to a tenant where I have Guest Access my tenant pick list doesn't include my primary tenant for my company. This is a new behavior since yesterday.

See title

I´ve added some guests participants to a team. They have no permission to bypass lobby, but some of them access directly to meetings they are invited to, without having to wait in the lobby.

The only way I found to solve this is removing them from the team in Azure.

Is this a bug? Or there is a way to solve it?

somebody outside my organization accidently sent a request to join their org instead of a request to join a meeting. there's no option given to decline the request, only "accept" and "cancel". cancel doesn't really do anything, and now I have a persistent notification that I can't get rid of, in both mobile and Windows app

in a Live Event this morning, externals with the Teams app were coming in to the lobby of our event group as 'allow external presenters' was turned on, even though they received the attendee link it was obviously not differentiating?

I got an invitation to a Team over gmail address. When I click on the invitation, I get prompted for a MS account, which I have. After I enter my MS account and set everything up, my Teams would load up with no teams joined or whatever. So basically I cannot access the team I was invited to at all whatever I try to do. I would always just get redirected to my MS profile which does not have the invitation linked to it.

If you try to join a meeting and unknowingly click on the wrong meeting link, it says “Someone in the meeting should let you in soon”, causing you to wait and miss the meeting.
If you try to join a Teams meeting at the wrong time or wrong day - same problem.
There are a dozen popular meeting apps that show an error message, which also makes this issue more of a problem. The Teams app should show an error message if you try to join a meeting when it is not about to start.

There is no way to change a Guest to a memberor vice versa, I incorrectly selected Guest to an email on the invite and I'm no longer able to select or change it to a member there shoud be always a way to select even with the same emails cause now when I try to add it again it remember the previous selection and cannot add it as a member anymore

Guest users do not have the inline translation of messages available to them, even thought it is activated in the tenant accessed as a guest. Can this please be made available.

I invited a Guest from another O365 tenant to one of my teams. When he tries to login to my tenant he gets a something went wrong error. Then, he created a team and invited me to it. I tried logging in and I get a something went wrong error, too.

I'm using the Mac application. I believe he's using the Windows application.

The process of creating the team channel and adding the guest seems to work fine. We each got invitations from the other in our tests.
