So it may just have been a coincidence regarding the address book.

If you continue to have problems, you may want to record an smtp.log
which will show more details about outgoing mail.

To create an SMTP.log In OE5+, go to Tools, Options, Maintenance,
Troubleshooting, Mail
You may need to close OE after doing the send for the log to get written
to disk.
The log will be in the Store Folder which is listed in Tools, Options,
Maintenance, Store Folder.

Thank you for your reply. I tried that, but it didn't help.

By accident I happened to be looking through my address book and
happened to
notice that the email addresses in the emails I was trying to send
were also
in my address book. Upon eliminating the addresses in my address book,
all
emails in question were sent out without any problems.

I don't know what the address book had to do with anything, but now
that
those email addresses aren't in the address book, I can send out
emails okay.
Thanks again for your help.

Since I installed the latest security updates from Microsoft
pertaining to
Outlook Express, I can't send out emails.

Using XP w/SP2.

- Did a telnet check and it was okay.
- Sent out emails from another computer (ME) using same email
accounts and
that was okay.

The error message I get is:

An unknown error has occurred. Subject 'test', Account: 'ws4u
Support',
Server: 'mail.emailbox10.com', Protocol: SMTP, Port: 25,
Secure(SSL): No,
Error Number: 0x800CCC0B

Any help is appreciated.

Thank you,
