#550 5.1.1 RESOLVER.ADR.RecipNotFound - New Exchange 2010 Server Install RRS feed

  • General discussion

  • Hello all. I have just setup a new Exchange Server, patched it to SP2.

    At first it needed to have the ISP open port 25 (they said that there is no reverse lookup as a result so hopefully this is not the issue.) Now I can send emails internally and externally but cannot receive any messages externally. The error is "#550 5.1.1 RESOLVER.ADR.RecipNotFound" so I am scratching my head as to why it is not working.

    Right now I am just using the OWA so no Outlook issues yet. Let me know what I need to send to this post to help resolve this issue.

    Thanks  SAS

    Because the SMTP address you're sending to doesn't exist.

    OWA doesn't use SMTP so you should never get a "RecipNotFound" error
    if you pick the recipient from the address list.
     
    If you're entering the recipient's address "by hand" they you're not
    using the right address.

  • Sorry for the long dealy in this.

    You were kinda right. It appears the issue was with the MX record. The priority was with the MICROSOFTONLINE and should have been with the internal Exchange server.

    Changing the priority of the MX records resolved the issue.

    Thanks for your help and sorry for the delay in this.

    Cheers  SAS
