William Eyler - 01 Dec 2007 20:19 GMT
I am on COMCAST.NET and using Outlook or Outlook express I receive and ERROR
message 550 5.1.0 Authentication required.
I have talked with Comcast and they have never seen this error.  I have not
changed anything within my mail system.  Oh by the way, I have a laptop that
is running VISTA and received the same error when sending and email using
Windows Mail.  I'm beginning to think I something has corrupted my system
with a virus.  My Norton scan reveals nothing.  Help!!!!!!

My word, comcast support is a bunch of loons.

If it's happening on two boxes and in three different software packages, I
would highly doubt it is a virus.

First:  Has it ever worked?
Second:  Have you walked through
http://www.comcast.net/help/faq/index.jsp?cat=Email#Outlook to verify that
your version of Outlook is configured properly?
(http://www.comcast.net/help/faq/index.jsp?faq=EmailOutlook18914 is the
specific faq for Windows Mail on Vista)
Third:  Focusing on Outlook, since that's what this group is about, what
version are you running?

Yes, it was working prior to November 20, 2007.  I had not tried to use
Outlook Express except as a test for Outlook.  Since both failed I was
thinking there must be some common feature that is used to send mail
outbound.  I don't have any issues receiving.
Yes, I have worked thru all the proper setups, I think, for Outlook and it
appears to be configured properly.
Running Outlook 2003.

If you look at
http://www.comcast.net/help/faq/index.jsp?faq=EmailOutlook18533, are you
configured to access SMTP on port 587?
Signature

f.h.

William Eyler - 02 Dec 2007 00:07 GMT
SMTP was checked with COMCAST as 25.  POP3 is 110.  This is stated as server
not as port.  Maybe I'm not looking in the right place.  This is under email
accounts and more settings.  Anyway I think according to COMCAST I have the
correct settings.

Ok, how about this.  That last URL I gave you.  Can you set up Outlook using
the steps in that URL and try to send mail?

Comcast is requiring other ports now and the Comcast support people KNOW
this.

This is getting a little more interesting.  I don't have Outlook open and
running yet I'm getting these send error messages anyway.  How can the system
be attempting to send messages when I don't have Outlook open?

Because either something kept it open, or you have it set to minimize to the
systray.  If you open up Task Manager, is Outlook.exe listed on the
Processes list?  Is the Outlook icon in the system tray at the lower right?
How did you close Outlook?

William Eyler - 02 Dec 2007 01:18 GMT
Tried 587 instead of 25.  Same result.

Task manager does not show Outlook open and it's not in the system tray.

The sending I was getting was because I put my PDA on to charge and
apparently that causes it to check for or try to send messages.

Ok, so, right now, on the Outgoing Server tab of More Settings, what options
are currently selected?
Signature

William Eyler - 02 Dec 2007 02:08 GMT
I set outgoing SMTP to 587.  This did not change the error received.

Going to stop now and watch MIZZO and OKLAHOMA.  

Talk more tomorrow.  Hope someone can come up with some answers.

Ok, nope.  Wrong place.

1)   Open Outlook 2003, select Tools from the top menu, and then E-mail
Accounts... from the pull down list.
2)  In the E-mail category, select View or change existing e-mail accounts
and click the Next button to continue.
3)  Select your comcast.net e-mail account and click the change button.
4)  On the Internet E-mail Settings page, click the More Settings... button
located in the bottom right corner of the window.
(steps stolen from above url)

Now, if you click on the Outgoing Server tab, what is currently selected?

It should look something like

The only thing checked on this screen is the radio button "Use same setting
as my incoming mail server."  The options are a check box for "My outgoing
server(SMTP) requires authentication."  This is not checked and shouldn't be.
A radio button "Log on using."  This is for entering a user name and
password.  A check box for "Log on using Secure Password Authentication
(SPA)."  This is not checked.  A radio button for "Log on to incoming mail
server before sending mail."  This is not checked.

Yes.  It should be.

Reread http://www.comcast.net/help/faq/index.jsp?faq=EmailOutlook18533.

Make sure it is set up EXACTLY like that.  Lets see if that fixes it.

Sorry I didn't pay closer attention sooner.  I finally clicked on the link
you posted and checked the example.  IT WORKED.  I'll try not to be so dense
in the future.

Thanks a bunch for your help.

I am not also experiencing the same issue, but only receive this error about
50% of the time. I have verified that no one is receiving the emails I am
sending. I have followed all of the steps in this thread and these settings
are not work. Any suggestions?

Norton strikes again . Get rid of Norton and then test.

I agree wholeheartedly - I always have a tumbler with a rich brown fluid at hand whenever I have to call them (which is seldom).

I am experiencing this error too!! I can recieve messages but I can't send
them. This problem just occured. I had the 'computer guy' re-install
microsoft 2003 and that is when this problem occured. I've been through many
websites checking how to solve and can find no solution. Will someone PLEASE
write back to tell me how to solve this disgruntling issue??

Thank you. Just respond to this post and I will check it frequently.

Well, then, configure the account to authenticate properly, just like the
error message tells you.

I am running Vista as well, Outlook 2007, using Comcast.net email and am now experiencing a similar problem. The only difference is that I only receive the 550 5.1.0 error back about 50% of the time. I have confirmed that no one is receiving any of my emails, but I am receiving everyone's sent to me. I have followed the instructions of this post to the letter and that did not fix the problem. Any other suggestions?

Thanks,

Grant in Nashville, TN

You have entered your <%User_ID%@comcast.net> email address in the user
name; the whole enchilada, as I have written it? You have checked the "My
server requires authentication" box on the servers tab of the account
properties?
