TAPI_E_WRONGEVENT
The property does not belong to this TAPI event type
TAPI_E_WRONGEVENT (0x80040055) means the caller asked an event object for information that its concrete event class does not expose. The event itself can be valid; the invalid part is treating it as a different event shape.
Evidence to capture
Record event type/interface, property or method queried, provider, object identity, and the callback that received the event. Check any cast or switch statement that selects event-specific accessors.
Focused correction
Branch on the actual event type and query only fields defined for that type. Do not retry the same unsupported property or treat this as a call-state failure.
