SMTP SSL Authentication issues with outlook 2007 (Plesk, using IMAP)

Some Outlook 2007 IMAP users have reported issues authenticating to our Plesk mail servers to send mail.

with an error: "This client does not support any of the authentication methods used by this server"

Here is a fix around this issue:

Display your account's outgoing mail (SMTP) settings in Outlook:

• open Outlook

• click on the Tools menu, then Account Settings

• Select your email account, and under the Outgoing Server tab

• leave My outgoing server (SMTP) Requires Authentication checked

• change security to TLS (instead of SSL)

• change port to 587 (instead of 25)

This will allow you to authenticate with our servers.
