In the Outlook main window, click File, then Info, then Add Account. This opens the Auto Account Setup screen.
Set the Manually configure server settings or additional server types checkbox and click Next to go to the Choose Service screen.
Select Internet E-mail, then click Next to go to the Internet E-mail Settings screen.
Enter your name as you want it to appear in messages in the Your Name field.
Enter your full ATT mail address (firstname.lastname@example.org) in the E-mail Address field.
Select POP3 in the Account Type list.
In the Incoming mail server (POP3) field, enter pop.att.yahoo.com and in the Outgoing mail server (SMTP) field, enter smtp.att.yahoo.com.
Enter your full ATT mail email address (including the att.net) in the User Name field.
Enter your ATT email password in the Password field.
Set the Remember password checkbox if you donâ??t want to have to enter your password manually each time Outlook 2010 checks your mail (believe me, youâ??ll get tired of doing that real quick).
Make sure that the checkbox next to Require logon using Secure Password Authentication (SPA) is CLEARED.
Under the â??Deliver new messages toâ?? heading, select New Outlook Data File to store your ATT mail messages separately from your other messages. The messages will appear in the Inbox with all the rest of your mail, but wonâ??t be stored with your other (corporate?) messages on the server.
Click More Settings to open the Internet E-mail Settings dialog box.
Click the Outgoing Server tab.
Set the My outgoing server (SMTP) requires authentication checkbox.
Select Use same settings as my incoming mail server.
Click the Advanced tab.
Clear the Leave a copy of messages on the server checkbox.
Enter 995 in the Incoming server (POP3) box.
Set the This server requires an encrypted connection (SSL) checkbox under Incoming server (POP3).
Enter 465 in the Outgoing server (SMTP) box.
Select SSL in the â??Use the following type of encrypted connectionâ?? box under Outgoing server (SMTP).
Click OK to return to the Internet E-mail Settings screen.
Click Test Account Settings. The Test Account Settings dialog box appears and Outlook sends a test message using the settings you have just entered. If the test was successful, a Congratulations! message appears in the dialog box. Click Close to close this dialog box. If you didnâ??t see the Congratulations! message, go back through this procedure from the top to check all your settings.
Click Next, then Finish.
NOTE: If the test shows that you can receive messages fine, but you canâ??t send them, I suggest you try the change below. It helped at least one user (thanks for passing this along Krista!) get her connection to send as well as receive after initially failing to send messages.
What to Try If the Regular ATT Outlook Setup Wonâ??t Send Mail
Here is a settings change you can make if you can receive mail but not send it. This change should get the sending side of the equation working properly.
In the Outlook main window, click File, then Info, then Account Settings. In the menu that appears, click Account Settings. This opens the â??Account Settingsâ?? dialog box.
Click the E-mail tab and then select your ATT account from among the list of accounts that appears.
Click the Change icon which appears above the list of accounts. This opens the â??Change Accountâ?? dialog box.
In the Incoming mail server (POP3) field, enter inbound.att.net and in the Outgoing mail server (SMTP) field, enter outbound.att.net.
Click Test Account Settings. The Test Account Settings dialog box appears and Outlook sends a test message using the settings you have just entered. If the test was successful, a Congratulations! message appears in the dialog box. Click Close to close this dialog box. If you didnâ??t see the Congratulations! message, go back through this procedure from the top to check all your settings. Donâ??t give up just yet.
Click Next until you see the Finish button, then click that.
That still didnâ??t fix the problem? Then the snag is probably caused by factors outside the ATT Outlook 2010 connection you just set up.
I will help you solve your issue
Dan is could be that you have entered the wrong pop address try the ones below for pop and smtp.
Incoming Mail (POP3 or IMAP) Server field, enter inbound.att.net
In the Outgoing Mail (SMTP) Server field, enter outbound.att.net
The Incoming mail (POP3) should be port 995 and the check box next to This server requires a secure connection (SSL) is selected.
The Outgoing mail (SMTP) should be port 465 and the check box next to This server requires a secure connection (SSL) is selected.
hope this helps
