Hi all,
I'm pretty new at using Exchange Server 2016, but I have successfully finished installing the program and configured a few minor things. Currently, I am waiting for my SSL certificate to be approved, but I am not able to send any emails to the Internet even with a self-signed certificate.
When I try sending an email from localhost/owa I get this error in my inbox saying that the email failed to send.
Remote Server returned '550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient not found by SMTP address lookup'
I know my problem may sound a bit broad but I've been struggling to find a good step by step guide or best practices for configuring Exchange Server 2016. Does anyone have suggestions for my error message or where I can find a good documentation for post installation? I would greatly appreciate it.
