Error Code: 50089 Microsoft Teams can't use.

Dear @Imbasan Group,

Thank you for posting your question in the Microsoft Q&A forum.

Please understand that our forum is a public platform, and we will modify your question to cover your organization domain name in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.

Based on your description, it's likely Error Code 50089 occurs when Microsoft Teams authentication fails due to an expired token or multi-factor authentication (MFA) issues. If I misunderstand your point, please correct me and provide more information (as screenshot of the issue) so I can support you more effectively.

Here are some suggestions you can try:

Try signing in again with your username and password. 

This often resolves the "flow token expired" issue by initiating a new authentication flow.

Check your device's date and time: 

Ensure they are set correctly and synced with a reliable time server.

Check your internet connection: 

Make sure you have a stable connection.

Restart your device: 

A simple restart can sometimes clear temporary issues.

Clear browser cache and cookies: 

If you are accessing the service via a web browser, clear its cache and cookies.

If you have tried all the methods above but the issue still persists. Since your email is a business account, your company IT team or Helpdesk may be able to reset your Multi-Factor Authentication (MFA) settings. As a forum moderator, I do not have administrative access to change these settings. Only your IT team has the ability to adjust or reset your MFA configuration. You can also refer to this Microsoft support article for more information: Manage authentication methods - Microsoft Entra ID | Microsoft Learn  

In case you are the only Global Administrator and you are completely locked out from the tenant. You might need to contact Microsoft Support team via phone service number: Customer service phone numbers - Microsoft Support. The agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access.   

I hope information above meet your expectation and can help you resolve the issue. If you have any other questions, please feel free to reach out.

No information about error code 50089 is present in the context. The context only documents specific Teams sign-in status codes (such as 0xCAA20003, 0xCAA70007, 0xCAA90018) and general guidance that, when a code is not listed, the issue must be escalated to the organization’s IT admin.

For this error code:

1. Note the full error details (error code 50089, Request Id, Correlation Id, Timestamp).
2. Contact the Microsoft 365 or Teams administrator for the tenant and provide these details so they can:
   • Check Microsoft Entra ID (Azure AD) sign-in logs for the corresponding Request Id/Correlation Id.
   • Verify that the account, conditional access policies, and tenant access are correctly configured and not blocked.
3. If the admin cannot resolve it from logs and configuration, they should open a support ticket with Microsoft, including the error code, Request Id, Correlation Id, and Timestamp.

If this is a school or institution account (Teams for Education), also contact the institution’s IT admin, as they control policies and access and may need to verify or restore access.
