The connection to the server failed. Account: 'mail.comcast.net',

Server: 'smtp.comcast.net', Protocol: SMTP, Port: 25, Secure(SSL): No,
Socket Error: 10060, Error Number: 0x800CCC0E
This error indicates that Outlook Express is being blocked from
accessing the Comcast email server. This can be caused by either:
1. You have a firewall application that is blocking Outlook Express
or the ports that is uses. Make sure your firewall is set to allow msimn.exe
full Internet access through outgoing ports 25 and 465, and incoming ports
110 and 995. If you need assistance with configuring your firewall program,
please post a new topic in the E-mail forum and indicate what firewall
program you are using and also mention the Outlook Express error message you
see.
2. Enable SSL for the incoming (POP3) or outgoing (SMTP) mail server
(this is indicated in the error message you get). To enable SSL for incoming
(POP3) server, open Tools->Accounts, double-click on the Comcast email
account, click on the Advanced tab, place a check in the This server
requires a secure connection(SSL) under the Incoming Mail section. To enable
SSL for outgoing (SMTP) server, open Tools->Accounts, double-click the
Comcast email account, click on the Servers tab, place a check in My server
requires authentication, move to the Advanced tab, place a check in This
server requires a secure connection(SSL) under the Outgoing Mail section,
change the 25 in the field above this to 465.

I've uninstalled Norton and am still unable to send the messages currently
in
my outbox. Here's the error message...

The Microsoft fix you referenced should only be used when you have
an undeletable message stuck in the Outbox or one of the other
mail folders.
I'm assuming you got this error while sending from home, while
you were connected to your home ISP, Comcast.
If so, it is likely that you are running a non-compatible antivirus.
Windows Mail is not compatible with most McAfee
or Norton security programs. Those will need to be
uninstalled, not just disabled.
After uninstalling your non-compatible antivirus, download
and install a more compatible antivirus like the free Avast:

Even compatible antivirus programs will need to have their
email scanning option turned off. For more on this topic see
