Hi Experts,

We have existing Exchange 2010 in the production and recently upgrade or implement new Exchange 2013 in the production. Exchange 2013 is currenty subject for testing and not yet gonna be front in the production. we need to test first the send and recieved between 2010 and 2013 before we introduce it on the production as primary.

We have tested the send and recieved via OWA from Exchange 2013 to 2010 but no success
Tested to send internal email from 2010 to 2013 still no success.
Tested Internal send and recieved from 2013 to 2013 it's sucess

Troubleshooting done :

  1. Create new Send connector in 2010 routed to MX record and added in the scoping the exchange server 2013 as source server.
  2. Created new Send connector in 2013 routed to MX record and added one of the CAS server 2010 in the scoping as source server.
  3. Add Host Record in DNS for Exchange 2013

    Hi YukiSun-MSFT

    I have been able to resolved the issue in internal send & recieved by Adding the IP address of Exchange 2013 to Exchange 2010 recieved connector. The default Recieved connector is already been disabled then i found out that there was s customized or newly created connector as replacement of default in 2010. So, the issue have been fixed by adding the IP address of Exchange 2013 to Exchange 2010 recieved connector ( servers Allow to relay Mail Notification )

    See the steps below :

    1. Open Exchange Admin Center in 2013
    2. Mail Flow>Recieved Connector> Dropdown the select server to : EXCH2010
    3. Check if Default EXCH2010 connector is disbaled then possibly there we're s replacement for this or you should create new one for this named "Servers allow to relay mail notification.
    4. Highlight it and click edit
    5. On the scoping Tab> Add the Exchange 2013 IP Address. then click save. Follow the screenshot below
