Office: Keine Anmeldung in Teams möglich

Leider kann ich mich seit gestern nicht mehr in Teams anmelden.

Fehlercode:

Correlation Id: b7fdbda1-490b-4d23-b25b-52c123c0a6e4

Message: AADSTS50020: User account 'xxxxxxxxxxx' from identity provider 'live.com' does not exist in tenant 'xxxxxxxxxx' and cannot access the application '1fec8e78-bce4-4aaf-ab1b-5451cc387264'(Microsoft Teams) 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.

Ich kann auch nicht auf die Sign in to your account zugreifen.

Hier wird mir der Zugriff verweigert:

Die eingegebene Benutzer-ID wurde nicht erkannt. Wenn es sich um ein neues Konto handelt, kann es einige Stunden dauern, bis Sie Zugriff auf die Dienste haben.Wichtig: Von
dieser Seite wird das Anmelden mit einem Microsoft-Konto noch nicht unterstützt. Versuchen Sie, sich mit einem Konto anzumelden, das Ihnen von Ihrer Organisation zugewiesen wurde, sofern vorhanden. Wenn Sie über kein solches Konto verfügen, fordern Sie ein
neues Arbeits- oder Schulkonto von Ihrem Administrator an und versuchen es damit noch einmal.

Kann jemand helfen ?

Vielen Dank.

Hallo

im englischen Forum wurde dazu folgende Lösung vorgeschlagen.

Thanks for sharing your experience on this forum and sorry for the inconvenience caused by this issue, we will try our best to help you.



According to your description, may I confirm that if this issue only occurred in Teams client? Kindly login to
Microsoft Teams on web client. You can use Chrome or any other browsers which support Microsoft Teams, try to identify the issue result.



If this issue only occurred in Teams desktop client, you can follow the steps as below to quit your Teams client first and then clear Teams cache to check the result:

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

2. Once in the directory, you’ll see a few of the following folders:

a. From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.

* %appdata%\Microsoft\teams\application cache\cache

b. From within ‘Blob_storage’, delete any files that are located in here if any.

* %appdata%\Microsoft\teams\blob_storage

c. From within ‘Cache’, delete all files.

* %appdata%\Microsoft\teams\Cache

d. From within ‘databases’, delete all files.

* %appdata%\Microsoft\teams\databases

e. From within ‘GPUCache’, delete all files.

* %appdata%\Microsoft\teams\GPUcache

f. From within ‘IndexedDB’, delete the .db file.

* %appdata%\Microsoft\teams\IndexedDB

g. From within ‘Local Storage’, delete all files.

* %appdata%\Microsoft\teams\Local Storage

h. Lastly, from within ‘tmp’, delete any file.

* %appdata%\Microsoft\teams\tmp



Meanwhile, for testing purposes, if possible, kindly tell to Teams owner that create one test team, add you as a member into that created test team and try to identify that if the issue still persists in that test team regarding this
Assignments.



If this issue occurred in both Microsoft Teams clients, we suggest you that kindly open Microsoft Teams in the different networks or alternate networks. Also, kindly disable firewall proxy or anti-virus to see the outcome.



If this issue persists, to narrow down this issue, could you please provide us detailed error screenshot about the Correlation ID?



Please have a try and share the result with us.

 

Leider brachte das keinen Erfolg.

Ich denke da liegt ein Problem mit dem Konto vor.
