HTTP_E_STATUS_DENIED

HTTP_E_STATUS_DENIED maps to HTTP 401 Unauthorized. Despite the historical reason phrase, this status means that the request lacks valid authentication credentials for the target resource.

What to check for HTTP_E_STATUS_DENIED

Inspect the WWW-Authenticate challenge to identify the authentication scheme the server accepts.
Verify token expiry, audience, issuer, clock skew, client certificate selection, or username/password credentials as appropriate.
Do not confuse 401 with 403: a valid identity can still lack authorization for the requested action.

RFC 9110: 401 Unauthorized

Diagnostic interpretation

This result has the HRESULT value 0x80190191. AllStat records the condition as “Unauthorized (401).”.

Evidence to capture

Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the denied operation.
Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original denied condition.
