Those look like recent Outlook versions. Good luck getting a group of
paying customers to upgrade.

And the Outlook Express version (detail provided a couple of days ago)
associated with XP Service Pack 2, in common with earlier versions, will
not. (And more of the paying customers use that.)

It's good to hear that Microsoft has caught up with mid-1990s
standards...perhaps in another 10 years we can forget about tls-on-connect.

Then there's Netscape 4, which demands a password be provided upon first
sending with authentication in use, each launch of the program. The
customers don't like that ("I never had a password!") That's what keeps us
from advertising SMTP AUTH in one situation where we'd like to.
