EventReporter Event ID 11089: IMAP Probe service: probe operation raised an unknown exception#

Answer#

IMAP Probe service: probe operation raised an unknown exception. The product recorded this while processing imap probe service; the appended event detail identifies the affected object, operation, or provider error.

Event details#

Event ID: 11089
Severity: Error
Component: IMAP Probe service
Windows Event Log source: Adiscon EvntSLog
Available since: 26.07
Message pattern: IMAP Probe service: probe operation raised an unknown exception. Additional detail: {event_detail}

Possible causes#

Name resolution, routing, listener state, TLS, authentication, or protocol expectations do not match the remote service.
The remote service rejected the request, exceeded the configured timeout, or returned an unexpected response.

Immediate checks#

Record the endpoint, port, TLS and authentication mode, timeout, and complete protocol response.
Resolve the host and test the configured port from the product system.
Run the smallest safe protocol test and compare its response with the configured success condition.

Detailed procedures#

Verify a monitored remote service — Confirm resolution, transport, protocol, credentials, expected response, and timing.
Collect an Event ID and neighboring product events — Preserve the complete event and the product events immediately before and after it.
Export configuration and collect a bounded debug log — Create a text configuration export and time-bounded debug capture, then disable debugging.

Verify the result#

Repeat or monitor the affected operation and confirm that Event ID 11089 does not recur and that imap probe service processing continues.

Evidence to collect#

The complete Windows Application Event Log entry, including all event detail.
The product name, exact version, service account, and event timestamp with time zone.
A configuration export and debug log covering the same time window, with secrets removed.

Escalation#

If the event continues after the detailed procedures, collect the listed evidence and contact Adiscon Support.
