Is there a way in Exchange to remove the hostname of the Exchange server in the message ID header? I would like it to be guid@our_official_domain.com and not guid@hosting _fqdn.

Regards

    Remove the headers:

    Then ensure the send connector FQDN is set to your domain

    https://learn.microsoft.com/en-us/powershell/module/exchange/set-sendconnector?view=exchange-ps 

    set-sendconnector <Internet Send Connector> -Fqdn YourOfficialDomain.com

    This assumes the cert assigned to SMTP contains your domain as a subject name
