    Hi David,

    If you have recently set the DNS records and added the mail alias to the mailbox then it can take some time to propagate (Global DNS propagation is 72 hours). I would leave it a few hours and then send to the mail alias again. If it doesn't work in this case then I would double check the DNS records, ensure that the domain is showing in the accepted domains in the Exchange Admin console, and that the alias is on the mailbox in the Exchange Admin console. If all of this is, then wait one day and try again. If this still isn't working, let us know and we'll investigate

    Hope that answers your question!

    Best, Chris
