Outlook 2007 is not sending mails Solved/Closed

Question

Hello, 

Have a nice day. 

I migrate my data from one PC to another. The old one was having Windows XP operating system along with Outlook 2003 while the new one is VISTA with Outlook 2007. I am receiving messages normally but not able to send any. Is there any changes in account settings that I should change? 

We checked our servers and I put the same settings on many other computers. It works normally putting in consideration that the PCs we tried are all having Windows XP and Outlook 2007. 

Is the problem from Windows VISTA?  
  
Just to inform that we are using genuine versions for all the products.

Thank you very much for your support & looking forward to hear from you soon.
System Configuration: Windows Vista Internet Explorer 7.0

Hey guys, this worked for me!

If you use Outlook 2007 as an email client to check your email, you'll need to update the settings.

To update the settings on Outlook 2007, do the following:

   1. Open Outlook 2007.
   2. Click on the Tools menu.
   3. Click on Account Settings.
   4. Select your AT&T email account and click the Change button.
   5. Change the following settings:

           Incoming mail server: Change your current settings to pop.att.yahoo.com
           Outgoing mail server (SMTP): Change your current settings to smtp.att.yahoo.com
           User Name: If you don't already have your complete email address entered here, do so now.
   6. Click the More Settings button.
   7. Click on the Outgoing Server tab.
   8. Change the following settings:

           Check the box My outgoing server (SMTP) requires authentication.
           Select Use same settings as my incoming mail server.
   9. Click the Advanced tab.
  10. Change the following settings:

           Check the box This server requires an encrypted connection (SSL) under Incoming server (POP3).
           Select SSL from the Use the following type of encrypted connection dropdown menu under Outgoing server (SMTP).
           Incoming server (POP3): Change your current settings to 995.
           Outgoing server (SMTP): Change your current settings to 465.
  11. Click OK.
  12. Click Next.
  13. Click Finish.

I had the same problem and it ended up being a DNS issue.  Once I created an a-record in DNS it started working.

Dear Sir,
I have outlook 2007 configured in pc and my operating system is vista. At the begining it was working good. I tried to create rules and after that I am receiving the mails from other servers but I can not send the mail to otheres. Whenever I send mail from my outlook, this mail goes to my own inbox folder. So, I am facing a problem for sending mail. Will you suggest me how I can solve this problem.
Thanks

Go to Tools
 -  Account Settings 
- Double click on required email displayed
- Click more settings - Select Outgoing server
- Check My out going server requires authentication and select Log on to incoming server before sending email. 
- Click Ok

This should solve the problem.

Howdy, 
I know this is a tad old, but future searchers may still run into this. 

I had this issue, and here's what my problem was. 

I use Trend PC-cilling Internet Security, and my personal firewall settings had about 30 entries for MS Outlook as an outbound exception. 
They all had the same exact settings. 
I deleted all but one of those firewall exceptions, doubled checked the remaining one had the proper setup, and immediately I was able to properly send & receive. 

I'm still researching how all those exceptions got in there (that type of thing makes me buku suspicious I may have caught a bug... ), but that solved the problem. 

I did not have to reconfigure Outlook, nor did I have to set up any DNS entries - but this may not be everyones case. 

I suggest checking firewall settings for whatever software you personally use. 
It's been my experience many times in the past that firewall settings can be improperly setup or corrupted somehow, and is often the culprit behind connectivity issues. 

Hope this helps someone, have a great day!

Resolved!  I spent two hours on the phone with a tech from ATT - NO HELP.

If you are having issues with the new smtp.att.yahoo.com sending emails from a third party, here is what I did that worked:

Go into account setting for the email you are having trouble with.
Go to "More Settings"
Click "Outgoing server"
Check "My outgoing server requires authentication"
"Dot" Log on Using
YOUR USERNAME AND PASSWORD IS WITH ATT - NOT YOUR THIRD PARTY!  ENTER YOUR USERNAME AND PASSWORD AND CLICK OK.  
Test settings - it will work - at least, it did for me!

After checking and rechecking all my email account settngs, changing some per what I found on WEB, checking my internet connection settings (DNS primarily)and much Googling.  I cured my problem by 

Loading my Office 2007 DVD into my DVD player.
Letting it configure Office 2007... figuring it would prompt to install after done.
   I didn't realize it but apparently it recognized I already had Office 2007 installed
   and it just configured and would never start install process.

Before I went ahead and deleted Office 2007 add/remove programs way I decided to try OUtlook one more time for the heck of it.  

Lo and behold Office 2007 regained all functionality (send/receive, etc0

So I didn't have to reinstall Office 2007 after all, apparently the configure fixed the problem.

Try it early on cause if it workis it can save you hours if not days of hassle.

I have Windows XP and MS Office Outlook 2007. I was sending emails to distribution lists OK, and suddenly see what happened: Outlook sends emails OK, they apparently go out but do not reach the destination. At least I tested including my other account in one of the distribution lists and never received it.
Could anybody help me to solve this problem?

Jorge · Answer

in my case it was avast antivirus that was blocking the emails from going out. I disables the TLS security in the Outlook account configurations for the outgoing server, and that did the trick.
