# Policy configurations for quorum queues for Amazon MQ for RabbitMQ
<a name="quorum-queues-policy-configurations"></a>

You can add specific policy configurations to quorum queues for your RabbitMQ broker on Amazon MQ.

 When you create a policy for quorum queues, you must do the following: 
+ Remove all policy attributes that start with `ha`, such as `ha-mode`, `ha-params`, `ha-sync-mode`, `ha-sync-batch-size`, `ha-promote-on-shutdown`, and `ha-promote-on-failure`. 
+ Remove `queue-mode`.
+  Change overflow when it is set to `reject-publish-dlx` 

**Important**  
 Amazon MQ for RabbitMQ applies all or none of the attributes within a policy. You cannot create a policy that applies to both classic mirrored queues and quorum queues. If you want your policy to only apply to quorum queues, you must set `--apply-to` to `quorum_queues`. If you are using classic mirrored queues and quorum queues, you must create a separate policy with `--apply-to`:`classic_queues` as well as a quorum queues policy. 

You do not need to modify `AWS-DEFAULT` policies because they automatically adopt the new queue type in the “applies to” parameter. For more information on default policies for Amazon MQ for RabbitMQ, see [Configuring operator policies](configurable-values.md#configuring-operator-policies).
