I have a Unity Connection 7.1.3 and Exchange 2003 and I had have some problems with the integration.
I configured the External Services of Unity Connection to Exchange 2003 server. I attached screenshot of the configuration. Too, I configure the SMTP in Unity, too I attached the screenshot of the configuration.
My client configured the Exchage Server follow the step of guide from Cisco.
I did some troubleshooting test of connectivity in both ways, from Unity to Exchange and Exchange to Unity. I attached the screenshot of the capture.
Can somebody help me?
