Unknown Error Sending RRS feed

  • Question

  • Exchange 2003 on SBS 2003. Clients use RDS outlook 2013 with imap/smtp configuration. Sending and receiving of emails to users inside fail with:

    Task '*** Email address is removed for privacy *** - Sending' reported error (0x80040201) : 'Unknown Error 0x80040201'.

    So, sending email to users with something other than @problemdomain.tld works fine but as soon as i send something to user@problemdomain.tld, we get the above error. I feel like this is a restriction on the exchange server as emails sent to non-exchange users works. How do i verify users can send through exchange smtp?

  • Does this help?

    Error 0x80040201 reported in Microsoft Outlook when sending

    Or this?

    getting error 0x80040201

    The fact that it works when you send messages to addresses that aren't on Exchange sure makes it look like the address you're sending to is a legacyExchangeDN and not a SMTP address.
