    Hello Kajol Kardam

    As per discussion over teams , Error 53003 indicates that authentication succeeded, but authorization was blocked by a Conditional Access (CA) policy in the resource tenant. To fix this, the CA policy is getting applied on your sign-in by taking help from global administrator in your tenant and exclude the application that is being applied.
