I've been using Outlook for my Yahoo mail for a year. Now all of a sudden, my Outgoing mail is not being sent. I checked the configuration and it seems to be right. (smtp.mail.yahoo.com.sg)(SSL encrytion, Port 465, etc.) Any ideas on what could be the issue? When I test Account Settings it says that Outlook cannot connect to my outgoing (SMTP) e-mail server. (Incoming works fine.)
