External users see meeting chat messages with their names but written by other external users.
Hello, I'm reporting an issue occurring when a meeting is organized with both internal users and external users invited to join a call.
Business context
The internal staff of a public agency under the Ministry of Labor frequently organizes meetings on Microsoft Teams. Both internal agency users and external stakeholders (public organization managers, entrepreneurs, school representatives, university professors, etc.) participate in these meetings. External users join a new meeting via a link shared through an invitation e-mail text.
Additional note: these external users are not previously manually mapped/added in Azure Active Directory, but are just invited through a link to join a meeting. In other words, they are not Guest users as well as there isn't any current federation and so on.
The problem reported
Since 19/01/2023, some external users have reported seeing some messages in meeting chats as if they where written by them, but these messages are actually written by other external users present in the meeting.
An example of what happened in one of these chat meetings
- External user John: "hello, I would like to highlight this is an important project we have funds for"
- External user Mary: "hey why I'm reading this message about funds for that project written with my name??? I've never said that! What's happening???"
Most of the external users as well as all the internal ones don't have any visualization problem. In other words, the respective real identity/displayed name match is correctly rendered for them during a chat meeting. Therefore, this mismatch just affects some external users.
The solution implemented so far
Kindly suggested to clear the Microsoft Teams cache, but with no success. The problem reported above still occurs again and again for some external users. No, we cannot ask for Microsoft Teams logs to be shared with Microsoft support staff, since these external users are partners and customers and this backend support process is not supposed to be provided.
The questions
- Have you ever heard about this weird issue?
- Is there a possible misconfiguration in our tenant?
- Is there any mistake related to how we organize these meetings with external users?
- Other ideas?
- When people are joining Teams meetings as anonymous users (not signed in) using a link and a browser they get to type in whatever name they like in the join meeting prompt. Hence James Bond, Pavarotti and 7 Bobby could be participating. That is built-in behavior of anonymous join. If that isn't the issue here I must direct you to the official Microsoft support.
For the record there are settings to control if anonymous join should be allowed, if they should be able to start a meeting and if anonymous users should be able to chat in meetings, meaning they have to be signed into Teams. If you don't allow federation it's an issue though as they will all join as anonymous users, that is if allowed.- Hello ChristianJBergstrom,
thanks for your reply. Yes, we are aware of the built-in behaviour of the anonymous join, but actually the issue is not related to what name users choose to write (James Bond, Pavarotti, Bobby etc.) during an anonymous join, but to what is displayed by Microsoft Teams on users' screens. Therefore, since there is still a mismatch between real identity/displayed name in a meeting chat, I asked my tenant admin to open a ticket with Microsoft Premiere support.
I will share any update about this issue.
Thanks again and best regards.Hello Feder365 ,
I've had the same behavior in a few meetings and was wondering if you ever received an answer from Microsoft ?
If you did, what was the cause of this issue ?
Regards.
