Hi @Niels

Welcome to Q&A Community! 

Thank you for the detailed description and the screenshot. Based on your report, the entries with warning icons are residual records of external tenants that remain in the Microsoft Teams desktop client after you have left those organizations in the browser. This is typically caused by cached tenant and authentication data stored locally by the Teams desktop app and related Microsoft sign‑in components. 

Below is a structured remediation plan you can follow. Please proceed in the order presented. 

Step 1. Confirm you have left the external organizations 

1. Open a private browser window. 
2. Go to https://myaccount.microsoft.com/organizations. 
3. For each external organization that you no longer need, choose Leave organization and confirm. 
4. If the organization does not appear, it may already be removed or your guest account may have been disabled in that tenant. In that case, continue with the next steps. 

Step 2. Sign out of Teams and close Office apps 

1. In Teams desktop, select your profile and choose Sign out. 
2. Quit Teams so it is not running in the background. 
3. Close Outlook and any other Office applications. 

Step 3. Clear Teams cache 

This usually removes the “ghost” organizations. For more detailed steps on this, kindly check this article: Clear the Teams client cache - Microsoft Teams | Microsoft Learn 

Step 4. Clear Microsoft sign‑in caches 

On Windows, residual sign‑in data can reintroduce old organizations into the account switcher. Clearing these local stores helps remove stale references. 

1. Open Credential Manager, then, choose Windows Credentials and remove entries related to Microsoft Teams, Office, and AAD Broker if present. 
2. Reboot the device. 

Step 5. Disconnect any Work or School accounts in Windows 

1. Open Settings, Accounts, Access work or school. 
2. If any retired external organization connection is listed, select it and choose Disconnect. 

Please try these steps and let me know if the issue persists. I look forward to your response.
