Need to use port 995 for incoming and port 465 for outgoing. At the present it does not work. Changed back to original ports and works.

You need to change the security policy as well - did you do that? If not, change it to Use SSL/TLS on special port (Legacy) and let me know if it helps.

George, Thanks! I had verified that I had used SSL according to what my service provider suggested. I switched both (defaulted to ports needed). Sent a test email and all is working.
