We have two offices, thehead officehas domain name fsl.co.uk our other site domainbranch.fsl.co.uk.The head office runs sbs 2003, if we send email to anything@branch.fsl.co.ukthe message disappears. Nothing shows in message queuesand the intended recipient doesn't receive.

This forum is for exchange related issues. For questions about SBS 2003 please use the SBS 2003 Newsgroup which would be the most relevant forum for the question Is branch.fsl.co.uk the child domain of fsl.co.uk? Because Windows SBS does not allow child domains (Refer to You cant create child domains section in this document) If branch.fsl.co.uk is not the child domain of fsl.co.uk, just another pure exchange organization or SBS exchange organization, we shall find out where the messages really goes.
