[KB6540] Agent 'ESET Filtering AV Agent' went async but did not call Resume on the new thread, while handling event 'OnSubmittedMessage'.

Windows Application Log shows an error Event ID: 1057 - Agent 'ESET Filtering AV Agent' went async but did not call Resume on the new thread, while handling event 'OnSubmittedMessage'.

This event message is being triggered due to Microsoft Exchange API and backward compatibility with older versions of .NET Framework.

You can safely ignore Event ID: 1057 because it does not have any effect on ESET Mail Security for Microsoft Exchange Server and the protection status.
