017-714 is an encryption error, usually means something is not supported, so I would guess you are on launch firmware and the mail server uses SHA-2.
Update the firmware, change nothing and try again
Scan to email results in the following error:
"completed with an error (017-714): Smtp over ssl failed"
Using our email provider, Rackspace, we have been able to scan to email on other printers, but for some reason this Workcentre won't handle it.
Any suggestions?
