What does HRESULT 0xC00E0083 (MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS) mean?

MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS

What this result actually narrows down

The important part of MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS is not only whether the call failed, but which MSMQ subsystem had enough information to return this specific result. In this case the decisive subject is legacy primary-site-controller ownership blocks delete. The object is governed by an old enterprise ownership model, not merely an ACL on a current queue.

For MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, A domain join, a successful DNS lookup, and an LDAP bind are separate checkpoints. When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, directory errors must be correlated with the exact naming context, object class, GUID, and domain controller used by MSMQ.

When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, MSMQ uses directory services for public queues, machine configuration, security metadata, routing, aliases, and related enterprise objects. In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, private/direct queue operation can therefore succeed while a directory-dependent action fails.

MSMQ objects involved

When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, A queue can exist locally while its public registration or MSMQ configuration object is absent, stale, wrong-class, or visible only on some domain controllers. For MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, the code-specific boundary is legacy primary-site-controller ownership blocks delete.

Triage data

• Domain/workgroup mode, forest and domain names, and selected domain controller; associate it explicitly with MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS.
• When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, dns and ldap reachability plus the distinguished name being accessed; capture the value before cleanup or retry changes it.
• In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, the directory object class, guid, owner, and replication state; compare it with a known-good call using the same account and queue type.
• For this MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS result, record the queue path or format name, local/remote placement, transactional flag, caller SID, process build, and UTC correlation ID when they apply.

For MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, log certificate thumbprints, provider names, SIDs, GUIDs, lengths, and hashes where useful, but do not log private keys, symmetric keys, credentials, or confidential message bodies.

A safe investigation order

1. Record the unsigned HRESULT, MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, and the native API or COM method before a framework replaces it with a generic exception.
2. When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, capture the directory object class, GUID, owner, and replication state.
3. In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, capture domain/workgroup mode, forest and domain names, and selected domain controller.
4. Reproduce with the smallest queue/message/property set that still returns MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS; change one precondition at a time.
5. For MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, verify the postcondition after the failed call: queue existence, message presence, directory object state, transaction outcome, or generated output may differ by result.
6. When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, apply the code-specific recovery rule: Perform migration-aware cleanup through the owning controller/tooling.

Correct response

Perform migration-aware cleanup through the owning controller/tooling.

When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, retry only after a measurable state change: corrected property data, resized storage, restored service/directory reachability, recreated handle, completed transaction recovery, or repaired certificate access. In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, bound attempts and keep an idempotency key for sends or directory mutations.

What this code is not

In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, local private-queue success does not prove that public-queue registration, global catalog discovery, or the required AD DS object is healthy. The specific focus for MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS remains legacy primary-site-controller ownership blocks delete.

• In the MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS path, granting broad queue or certificate permissions may mask the symptom while creating a security defect. For this MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS result, test the exact identity and access needed by the operation.
• For this MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS result, changing queue names, deleting directory objects, or recreating certificates without reconciliation can create a second object while callers still reference the first.

Example failure path

An enterprise migration tool encounters MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS. For MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, it compares DNS, LDAP bind, object class, and replication on the exact domain controller used by MSMQ. When diagnosing MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, the acceptance test then changes only the decisive precondition and confirms both the HRESULT and the actual queue/message state.

A regression test should force MQ_ERROR_CANNOT_DELETE_PSC_OBJECTS, assert the raw value and relevant outputs, then correct only the documented precondition and verify the intended success or neighboring HRESULT.
