Hello Mike,
Thank you for your update.
I have read your original post, and I know your ISP request you to encrypt
the SMTP traffic to it.
I want to explain that:
1. The TLS encryption is used when Exchange server communicate with other
Exchange server when transfer emails via SMTP protocol. TLS should not
related to communication between the Outlook client and the Exchange
server. The SSL encryption is used when clients communicate with Exchange
server when transfer emails via SMTP protocol.
TLS is designed to help protect outgoing messages, but TLS does not help
protect traffic that travels from clients to the server. These clients
include Microsoft Outlook Web Access (OWA), POP3, and IMAP4 in particular.
To fix this problem, you can enable the use of Secure Sockets Layer (SSL)
with Outlook Web Access. You can also suggest that POP3 or IMAP4 users use
a client that supports the use of SSL with POP3 and IMAP4 (for example,
Microsoft Outlook Express).
2. The TLS and the SSL are all used for encryption SMTP traffic, TLS for
server to server, SSL for client to server. Therefore, you will find the
SSL options available in Outlook, but you can only find TLS in SMTP
connector.
3. The connector that let you forward outbound mail to ISP is a SMTP
connector. We can enable TLS but not SSL on the SMTP connector.
I hope the information give you some help.
Thanks and have a nice day!
Best regards,
Terence Liu(MSFT)

| Thanks for your reply, but your suggestion has nothing to do with my
| goal. I think you're referring to the wrong connector? I'm talking
| of the connector that lets you forward all outbound mail through a
| different SMTP server (usually your ISP).
|
| TLS is not SSL last I checked, and I also need to specify a port
| number of 995 for the server I'm trying to send through. I don't see
| those options anywhere.
|
| These options are all avilable in Outlook...just not in these
| connectors.
|
| Please re-read the posts I've linked to so you get a better
| understanding of this problem.
|
| Thanks,
| Mike
