Queues stuck, user locked-deleted

Hello Sap Experts,

I have several Queues that are stuck with 2 errors:

     - User is Locked

     - User account is no longer valid

Queues affected by this are:

     - CSA_ORDER*

     - CSABUPA*

     - CRM_BT_LRP

     - WFM_CORE2PUBLISH

All of the users related to those Queues have been permanently Locked from the system because they have left the company.

Is there any way to process those Queues without unlocking those users? How could I achieve this?

Thanks and regards,
