Can't join Teams meetiing

Question

Hello, A client send me an email to participate a Teams meeting.

His email got naturally a link to access the meeting, an ID of the meeting and a secret code.

I can go to the page and enter the id and secret code but sadly, when i try to join the meeting, i got an error message that refers to an old company i used to work in Teams.

"AADSTS50020: User account 'xxxxxxxxxxxx' from identity provider 'live.com' does not exist in tenant 'yyyyyyyyy' and cannot access the application....

I don't understand why Teams wants to use this old tenant that i no longer have access, despite giving meeting id and secret code. It should use the company linked to this team meeting ?!

Hi @Marc FLAUSINO

When you click on the meeting link, do you choose the Teams desktop client or the Teams web client?If you use a desktop client, try quitting the Microsoft Teams desktop client and clearing the Teams cache:

1. If Teams is still running, right-click the Teams icon in the taskbar, and then select Quit.
2. Open the Run dialog box by pressing the Windows logo key 

 +R.

1. In the Run dialog box, enter %appdata%\Microsoft\Teams, and then select OK.
2. Delete all files and folders in the %appdata%\Microsoft\Teams directory.
3. Restart Teams.

Answer 2

Hi @Marc FLAUSINO

It sounds like the issue may be related to the account you are using to access the Teams meeting. The error message suggests that the account you are using is associated with a different tenant than the one that the meeting is hosted in.

One solution could be to try logging out of all Microsoft accounts and then logging back in with the correct account that is associated with the tenant hosting the meeting. You could also try clearing your browser's cache and cookies before attempting to join the meeting again.

If these steps do not work, you may need to contact the meeting organizer or your IT department for further assistance. They may be able to provide more specific guidance based on your organization's Teams setup.

Hello @Anonymous , thanks for your reply. To answer your questions i was trying both with browser and desktop app.

So i deleted all files on %appdata%\Microsoft\Teams folder and it worked for the desktop app.

I tried the web url and still have issues so i did clear the browser cache as @JimmyYang-MSFT suggested and it worked :)

So thanks to both of you !

nb : It is sad there is no button in app to remove specific tenants from cache.
