+## Other scenarios and limitations
+With support for both system-assigned identity and user-assigned identity, here are some scenarios and limitations to be aware of when configuring your Azure stream analytics job:
+
+1. You can switch from using system-assigned identity to user-assigned identity and vice-versa. When you switch from a user-assigned identity to another identity, the user identity is not deleted since you created it. You will have to manually delete it from your storage access control list.
+2. You can switch from an existing user-assigned identity to a newly created user-assigned identity. The previous identity is not removed from storage access control list.
+3. You cannot add multiple identities to your stream analytics job.
+4. Currently we do not support deleting an identity from a stream analytics job. You can replace it with another user-assigned or system-assigned identity.
