AADSTS50020 can't login to teams account

piotr cierkosz 41

Got invited by friend, then decided to setup my own teams. SO after being removed from his organization my teams stopped working.
MY office365 still working correctly

Error:
Sorry, but we’re having trouble signing you in.

AADSTS50020: User account 'piotr.w.cierkosz@Stuff .com' from identity provider 'live.com' does not exist in tenant 'PrismCode' and cannot access the application '5e3ce6c0-2b1f-4285-8d4b-75ee78787346'(Microsoft Teams Web Client) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

The issue is that you have a personal Microsoft Account that matches a domain name that is registered as a tenant in O365. Incognito browser, login in to microsoft.com/account with the email that is not working.

Go to your Info, add new DIFFERENT email address that is not a Microsoft account with your org (consider a new outlook account if you want or a gmail).

Go to that email and confirm it.

Make that new email primary.

Remove the old email from the account.

BAM - problem solved.

Hi, I encountered the same problem while trying to access school work.

Head to this link here (Microsoft Azure): <https://azure.microsoft.com/en-au/>

Look in the top right, and log out of whatever account is signed into it.

You should be able to access teams properly from then on.

I got the same problem.

I'm trying to access the misionTIC2022 classes. I'm a student. I thought all I had to do to access the classes through the TEAMS app was to sign in with my outlook account and join the meetings. But I have not been able to do anything. Keep receiving the same error.

I have tried everything shown on this page to fix this problem.

I already accessed the roaming directory and deleted everything as suggested by SharonShao-MSFT

I uninstalled the app and installed it again twice. I logged out every account of mine on the azure website.

non of these have worked at all. I'm unable to take my classes because of this. I would deeply appreciate it if anyone can instruct me about what to do.

This is not a right solution. No one would set such policies for people to change emails.

I just solved this on my own.

For me personally, it's because I was connected to a previous work account and school account that I was no longer using.

I fixed this by:

Start menu > Settings > Accounts > Access work or school

From there, it shows all my other accounts affiliated with me. Click the 3 dots on the right and remove any ones that are not the one you are currently using.

It no longer asked me to sign in, and it no longer was giving me that error.

I hope this helps someone!

Hi piotrcierkosz,
It seems that the error message is a Azure AD login error. This article give a explanation of the issue: http://www.agilepointnxblog.com/windows-azure-active-directory-login-error-aadsts50020/.
It recommends you delete your Teams client cache as the following steps:

Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’. Or run Task Manager and fully kill the process.

Go to File Explorer, and type in %appdata%\Microsoft\teams.

Once in the directory, delete any file in the following folders:
%appdata%\Microsoft\teams\application cache\cache
%appdata%\Microsoft\teams\blob_storage
%appdata%\Microsoft\teams\Cache
%appdata%\Microsoft\teams\databases
%appdata%\Microsoft\teams\GPUcache
%appdata%\Microsoft\teams\IndexedDB
%appdata%\Microsoft\teams\Local Storage
%appdata%\Microsoft\teams\tmp
If it is no luck after that, you could uninstall and reinstall the Microsoft Teams client and have a try.

Thank you, this solution worked for me.
On Ubuntu, the directory (at least for me) is:
~/.config/Microsoft/Microsoft Teams/

I am having really bad experience with microsoft teams. Every time I login I get this message. I want to know why this message is popping at my screen. Is my microsoft account working properly. Is everything going fine. Is there some issue in my microsoft login account. This issue is not faced by many people. What is Azure AD directory user account?

Message: AADSTS50020: User account '@Stuff .com' from identity provider 'live.com' does not exist in tenant '' and cannot access the application '5e3ce6c0-2b1f-4285-8d4b-75ee78787346'(Microsoft Teams Web Client) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

I contacted to support, and they found the solution! The problem is, you have registered your account as personal from your mobile device, which means, you can not use desktop app.

To fix this, create/use existing (but different from your current Teams account) email. It should not be private(@mydomain.example), it should be public(@Stuff .com, @harsh.com .com, @icloud.com). It can be the same as your Microsoft Account, if you didn’t use that email to create your current Teams account you are experiencing issues with.

After that, you need to go by this link: https://www.microsoft.com/en-us/microsoft-365/microsoft-teams/group-chat-software

Select English language and go: “Sign up for free” -> Enter your new/existing email -> choose “for work and organizations” -> fill your Name, any organization name, select your Region(! In some countries WEB version of Teams is not available yet), I recommend to choose US, as I know, there should not be any limitations. -> DONE!

You have successfully created a free work account, that you can use on any device!

Nothing worked for me. I'm still getting the same issue.
Logged out from my company account and trying to reconnect with my private one.
No way.

Error still

aadsts50020: user account 'xxx@xxxit' from identity provider 'live.com' does not exist in tenant "xxx@X .onlinemicrosoft.com"...

Is a nightmare!!! Teams is really impossible to use. We were plannin to implement teams as our streaming default platform, but with these issues is impossible! We will keep the older one...

I think that if I logout from teams it shouldn't keep info of the older account, and should let me in with any other valid account.... it is like my company account locked teams forever in my pc and in my mobile phone...
UNBELIEVABLE!!!

Mostly agree! But maybe I could help you. Try to use web version of teams, usually, it uses much more transparent authentication algorithms. If it wouldn’t work for you, then try your luck and contact the support team!

Also, once this error appeared again to me, but then I just repeated the authentication process, and after I have entered the password, it has shown me a drop menu, that asked me if I want to login into Personal account, or “Organisation name” account. I have chosen one that was for work, and everything worked fine than.

Hi, thanks for the answer.
I tryed with both web browser app and desktop app... nothing at all.

We choose to dismiss totally Teams from our commercial plans, and we decide to keep zoom as platform for the streaming.
We are a AV company, and we need affordable and easy to use platforms, and we can't risk to lose clients cause similar problems.
A final user shouldn't have to deal with similar issues, but he need to put username and password and than speak, or attendee to a web conference...
