After Migration to Exchange 2013 I can send external emails but unable to receive.


  • Hi

    Recently I have migrated from exchange 2007 to exchange 2013 and as of now its co-existence setup with 2007 and 2013

    I can send & receive emails normally without any issues but as soon as I switch off my exchange 2007, I can send external emails but unable to receive external emails, I am using the same send & receive connectors without any changes.

    any help please.

    if you need more information please reply me.

  • That probably means that your inbound mail is being directed to the Exchange 2007 server.  You should change that.  That might mean changing your MX record, NAT mapping, firewall and/or ISP or cloud relay services.

    By the way, you shouldn't turn off an Exchange server like that.  There are better ways to determine whether it's being used.
