A partner at a different organization invited me to join a Team. I can't access the account--the issue:
1. Clicked invite to join Team created by partner
2. Signed in to Teams using my Office 365 Premium account (joined to my business domain)
3. The Team doesn’t display under the ‘Teams’ section
4. The notification next to my account name tells me I have six new alerts/messages (I also received six email alerts stating I’ve been tagged in a discussion in the Team I was invited to)
5. When I click on my account name, it show me an alternate account I didn't create called 'Microsoft (guest)'. The notifications are attached to this account, not my primary business account. T

1. When I click on the 'Microsoft' account, I receive a pop up: “Want to switch to Microsoft? We might ask you to sign in again.”
   When I click Yes, Teams refreshes, auto-signs me back in and loops back to the same alert (step 6). From then on, I’m stuck in the same loop.

Please fix this bug. On Android guests can log into Teams if they first log in on the Teams web app. But on iOS browsers (both Safari and Edge), the link to join a team takes user to the mobile site, and there is no option to open the Teams web app, even if they request desktop site (except on older devices like iPhone 5S).

This bug has been confirmed on multiple devices (iPad, iPhone 8, etc. as well as with the newest version of iOS (13.5.1))

Even if users first log into Teams web app on desktop and then try to log into guest account in iOS mobile app it doesn't work (see error message attached).

Please see this bug for more info and a video https://microsoftteams.uservoice.com/forums/908686-bug-reports/suggestions/38737450-guest-users-cannot-log-in-into-teams-on-ios-device (I posted here so it is in the right category)

Thank you in advance for providing support.

So, I have a multiuser tenant which runs a secondary school, what we have witnessed is students abusing the lobby notification feature using the anonymous access via the meeting url.

So, a legitimate student joins the class video call.
They get the meeting join URL from the ellipsis menu\meeting info.
They paste that into an incognito browser window and join via the anonymous feature whereby they are asked to enter a name.
They either enter the name of another student in the meeting to fool the teacher in to thinking they are legitimate or type anything and constantly request to join.

The issue is compounded by virtue of several students taking part in this venture resulting in a constant flurry of notification sounds of people waiting in the lobby.

I must stress at this point the users are locked down very tight as per documentation.

I've also checked the logs for said users and the IP reported belongs to Microsoft so there is no way for me to correlate an IP to the learners who have logged in to teams :(

A few days ago, any new Guest users cannot be found when searching for them in Teams.These are users that have been onboarded to AAD outside of Teams.

The only way to add them is to search by email in the search bar, then go to the Team, then the Guest is found.
Have logged a support ticket, but I got told it's by design.

This only started occurring a few days go, and now it's complex for a user to add a Guest to a team without knowing their email address (ie can't add by name until the cache? is populated by searching users by email address)

Dear smart MS teams global product design innovation team!!!

my feedback:

The guest access rules are designed in a way, that create a lot of problems in collaboration of different companies and really gives me and my customers a lot of frustration. We are forced to use MS teams, because of the Microsoft success in Germany and Europe with it's strong data security regulations... But we start to really hate it.

Why:

21 century businesses are build on cross organisational collaboration.
The structure of the MS Teams application design is meant for internal company use. COVID boosted the need to do all kind of meetings in the MS teams app, especially cross organizational meetings and workshops.

Please give us very soon an update or product design change, that enables cross organizational collaboration in a better way.

or change the accessibility of the guest Access

make it possible to see all participants of a meeting, workshop
(we want to conduct Workshops with 15- 200 and more people)
If we invite them to our organisation, they cannot see the videos or change the sight....
If we come to their organisation, we can only see 9 pictures. How do you think, we can be successful with that?
impossible, frustrating and business destroying for us

show all images for guests!
create a different type of user

Enable external facilitation!!!
there a millions of consultants, design thinking Experts, high Quality Change Makers, who will love this innovation

I am looking forward to be reading your ideas for a change in the product design of MS teams - then I will be happily wearing
I love MS teams stickers

thanX
