Trying to connect to Exchange Server 2003 using IMAP.

"receiving mail" settings work over SSL on port 993,

However sending email under SMTP using port 465, I get the error message . "SSL connection failure. Please check host and port settings." I have also tried enabling disable TLS / Required SSL on the mail server under SMTP virtual directory and still get this error message. When I uncheck SSL, it defaults to port 25 and works.

I have tried different ports and still get the same error.

Would appreciate any help in this regards and thanks in advance
