SESC has encountered Exchange Client Throttling policies. The EWS subscription could not be created. Since the EWS subscription is not created spam submitted to the folder is not processed by SESC.
The specific policy encountered is listed in the error message:
This operation exceeds the throttling budget for policy part 'CAS', budget type: 'EWS'.
This corresponds to the EWSPercentTimeInCAS throttling policy.
