Hi @Sagar Chaudhuri · Thank you for reaching out.
As you have mentioned, Supported account types is set to Multiple organizations. However, if your authentication call is for specific tenant i.e., https://login.microsoftonline.com/your_tenant_name_or_id
, users from other organizations won't be able to access the application and are required to be added as guests in the tenant specified in the request.
In your case, authentication request should either be for https://login.microsoftonline.com/organizations
or https://login.microsoftonline.com/common
