Outlook 2003 does not send E-mail & crashes

[Joel]

My ISP (Yahoo) insists that I send mail SSL which has been no problem until
the last week or so. Outlook now asks permission to use a key (there are no
details) and I get the following error message when sending: "Task
'pop.att.yahoo.com - Sending' reported error (0x800CCC7D) : 'Your outgoing
(SMTP) server does not support SSL-secured connections. If SSL-secured
connections have worked in the past, contact your server administrator or
Internet service provider (ISP).'" It has crashed a number of times.

I've gone over my E-mail settings with Yahoo, and everything is OK. I've
tried repairing Outlook, and I've run updated versions of Norton Anti Virus
and Windows Defender: everything seems to be O.K.

I am able to send mail without SSL, but Yahoo doesn't like that.

Any ideas?

The first thing to try is to open Internet Explorer, click Tools>Internet
Options>Advanced and, in the Security section, uncheck the box labeled
"Check for server certificate revocation". Close IE and try again. If that
doesn't work, post back. I've seen some messages about SSL certificate
expiration with respect to Yahoo and Outlook and I'm wondering if your issue
is related.
