It totally depends on what queue it is. Is this a response of their own Exchange server, or is it a response of their own Exchange server AFTER a conversation with the destination server (it will tell you in the error message, the responsible server).
That way you know if it's YOUR queue that's expired, or the other queue.
Assuming for now that it's your own queue, check your logs or use Wireshark to check the whole email conversation why the email is not being accepted. If nothing shows, it could be a wrong email address or DNS entry (and your mail server tries to connect to an IP that's not responding).

Don't worry about the winmail.dat line, that's normal.  Assuming this is an Exchange server, check the SMTPSend protocol logs for a detailed view of the SMTP conversation between your server and the recipeints:

%ExchangeInstallPath%\TransportRoles\Logs\ProtocolLog\SmtpSend

The path for Exchange 2013 is:

%ExchangeInstallPath%\TransportRoles\Logs\Hub\ProtocolLog\SmtpSend

Verbose logging has to be enabled:
