MQ_ERROR_ILLEGAL_RELATION: an MSMQ query relation operator is invalid for the selected property or restriction
MQ_ERROR_ILLEGAL_RELATION identifies a narrow contract boundary: an MSMQ query relation operator is invalid for the selected property or restriction. Do not replace it with a generic subsystem failure when the symbolic result already tells you which state or input was rejected.
Evidence
record property, relation operator, comparison value/type, query restriction array, and the failing locate/query API.
Verification
use a relation supported for that property and value type, then rerun the same directory query.
