Question that I can't quite figure out
I have a customer who bought a server to host their email. Exchange 2016, fully patched and updated.
Their website/domain is hosted externally with an online hoster/designer, and the customer called and asked me to come in and get their Exchange connected and setup.
I can't quite figure out how to get it connected to the offsite hoster. They customer does not have their own Static IP address.
I have set the MX records in DNS, firewall is as open as I can make it - but the send/receive just doesn't work - at least not consistently. I have gotten a few emails to send out, but can't receive anything - internal or external.
Any thoughts? Suggestions of things to check?
Thanks
Randy
