We're got Unity 5.x/Exchange server. It is VM only. We want to implement MESSAGE NOTIFICATION w/o Unity Inbox (no license for Unity Inbox). I'm trying to send a notification using the TEXT PAGE 1 option, for my testing, to my company email address. Our SMTP gateway has been correctly configured. A 'sendmail' utility works successfully on said Unity server. However, the Message Notification part of Unity fails. The messaging group tells me they do not see any relay from our Unity server. I am stumped as to what the problem could be. I cannot identify any configuration parameters in Unity of any additional items I need to include, change, whatever. Any and all help would be most appreciated. Thank you.
I would also check Exchange System Manager message tracking on your Unity server, since Exchange is on-box and also on the Exchange server that houses the user's email. Look for a sender called Unity Messaging System - unityservername. Unityservername is your Unity server's host name. Also check inbox for Unaddressed messages to see if you have anything stuck in there. Ginger
