  • NDRs cant send emails out

    I have a exchange 2016 server that i just stood up and i am unable to send emails internally to another exchange in another forest, and i cant send mail to my environment from the outside. I know i can reach my exchange server from the outside because owa works. I posted the NDR below

    Now i am sending this email from my functional exchange 2010 server, to my new exchange 2016 server in another forest. There is a domain trust set up between my DCs
