Hi @Contact NaT
To integrate Azure DevOps with Microsoft Teams, the DevOps organization must be linked to the same Azure Active Directory (AAD) used by your Microsoft 365 and Teams accounts.
To check that Azure DevOps is connected to Azure Active Directory or Microsoft Entra as Microsoft Teams Go to:
Azure DevOps -> Organization settings -> General -> Microsoft Entra.
If the organization is connected to Azure Active Directory, you will see the screen shown above. Verify that both Azure DevOps and Microsoft Teams are in the same directory.
If it is not connected to Azure Ad, connect the Directory by navigating to:
Organization settings -> General -> Microsoft Entra -> Connect directory -> Microsoft Entra -> Connect.
After Verifying the above steps Connect the Microsoft teams to Azure DevOps by navigating to:
Microsoft Teams -> Apps -> search for DevOps -> Add DevOps.
For more details refer this Documentation.
Hope this helps.
