Outgoing Outlook mail with Comcast

[jemilo]

Comcast cable was installedyesterday and new account in Outlook, which worked
fine for a day. Now I'm getting error messages on outgoing mail: " Unable to
send the message. Please verify e-mail address in account properties (which I
did). Server responded: 550 5.7.1. Access denied." Comcast won't help with
Outlook.
Thanks!

What SMTP server are you using in the account? Is it one from Comcast or is
it from a previous ISP? If it's not a Comcast server you'll probably have to
switch it to one since many SMTP servers won't allow you to use them for
sending if you're not on their network

Thanks Vince ... I can't tell what smtp server I'm using ... I just filled
out "new account" forms in Outlook. How would I switch to a Comcast server?

Howdy,

Not Vince, but...

I, too, use Comcast, and Outlook.

The folks at Comcast have helped me on many occasions. Not
all of 'em, but many of 'em, are happy to help.

I would suggest calling them again.

All the best,

I am having the same problem. I get it every once in a while. This time I
have unplugged everything. I have reset all the account settings several
times. I went through this with a Comcast tech to verify again. I have the
Comcast account for quite some time. I haven't added or removed software. It
is as if something freezes some switch or something. I have gone to:
"www.comcast.net/help/faq/index.jsp?faq=SecuritySpam17867" and even verified
with another computer that is right next to this one. Any other suggestions?

I have been having trouble sending in Outlook 2007. Just installed last week
& was working fine. Outlook did the setup for me so I'm not sure what (or
exactly where) the screen for that is. As of Saturday 10th I had been able to
send and recieve mail. I have been able to recieve mail all along but have
not been able to send out since yesterday. . I have Comcast too. The send
error message is 0X80042109. Any thoughts?

As of this morning Outlook is behaving. Here's what I responded to another
message in this group - hope it helps:

Don't know if this will help you but I had the same problem & asked a
microsoft tech. I just bought a Vista computer and installed office standard
2007. Outlook worked fine for about 5 days then all of a sudden wouldn't send
(I could recieve). I'm using Comcast broadband and the tech found an article
on their website which suggested with the disclaimer that it was not a
microsoft web page. The fix was for Outlook 2003 but it did the trick for my
Outlook 2007. If I knew how to do it I would paste the link here but not sure
if that is accepted practice. Here's the instructions:
1 From the Tools menu, click on Account Settings
2 Highlight the Comcast.net account and click Change
3 Verify that your mail settings are correct and click More Settings
4 In the Internet E-Mail Settings window, click the Outgoing Server tab and
check the My outgoing server (SMTP) requires authentication box.
The Use same settings as my incoming mail server radio button should be
selected as well.
5 Click the Advanced tab and change the Outgoing server (SMTP) from 25 to
587. Click OK.
6 On the Change E-mail Account screen, click Next
7 Click Finish
