Please provide unique value..
The error message means that such customer ID is already occupied on Microsoft side and can not be used.
You may cancel the task, then remove O365 service from the subscription
<SUB_ID> and then order O365 service on subscription anew from scratch in order to let the system to generate a completely new customer ID.
If such approach is not suitable in your case (e.g. the existing services contain valuable configuration/settings), please contact Microsoft to clarify why the customer ID
<CUSTOMER_ID> is already in use on their side.
