Remarks
A damaged or missing local copy records a repair request before the refusal, exactly as reading the message's content does. The finding is about the stored copy rather than about who asked for it, so discarding it because the request happened to arrive through a link would leave a defect discovered and unrecorded.
Exceptions
- ArgumentNullException
Thrown when
