Applies to:

Oracle Communications Messaging Server - Version 7.0.5 and later
Information in this document applies to any platform.


Outlook cannot submit messages over SMTP submit port 465/TLS;  it times out.  It works fine for port 465/SSL.

Outlook also cannot connect to:

-IMAPS: port 993/TLS, but the connection works for port 993/SSL

-POPS: port 995/TLS, but the connection works for port 995/SSL

Outlook will produce the error "operation timed out waiting for a response" when SMTP is configured to use port 465/TLS
