Teams channel integration

[JK9903]

Hello everyone,

We are trying to integrate Now Assist with Microsoft Teams from Instance A (Zurich release).
However, the same Microsoft 365 tenant was previously integrated with Instance B.

Instance B has since been completely disconnected, we removed all Teams/ServiceNow mappings and even zBooted the instance.
On the Azure AD side, we also deleted all related ServiceNow Enterprise Applications and app registrations.

Despite this cleanup, when we initiate the Teams integration from Instance A, we still receive the message indicating that the Teams tenant is already registered with another ServiceNow instance and cannot proceed.

Configuration Steps:

Install your teams again in Instance B using Install Azure Apps module and Authorise. Then uninstall it.

Now login to your Instance A and try to install using Install Azure Apps. That will work.
