The Microsoft Exchange Server Analyzer Tool queries the Active Directory directory service proxyAddress attribute value for all user objects to determine whether there is a match for the user-specified local sender Simple Mail Transfer Protocol (SMTP) address.

If a user object proxyAddress match is found, the Exchange Server Analyzer then queries the Active Directory msExchHomeServerName attribute value of the user object to determine whether that value matches the user-specified Exchange Server name.

Finally, the Exchange Server Analyzer queries the SenderAddress property for the Exchange_MessageTrackingEntry Microsoft Windows Management Instrumentation (WMI) class under the root\MicrosoftExchangeV2 namespace to identify any messages tracked by the message tracking logs as being from the user-specified sender.

If the Exchange Server Analyzer cannot find a message tracking log entry with a senderAddress property value that matches the legacyDN or SMTP address of the user-specified sender, the Exchange Server Analyzer displays an error.
