From what I know, the letter F that you see at the end of the error message stands for Firewall. Try to turn off the Firewall on your computer and see if you can send emails.
Also make sure that you are using Service Pack 3 on your Outlook 2002. Some versions of this email client cannot accomodate the recent changes AT&T made to make sending and receiving more secure unless you upgrade to Service Pack 3.
There are actually several reasons behind this 0x800ccc0F error in Outlook 2002. Aside from incorrect e-mail settings, it could be due to a corrupted e-mail profile, conflicting settings of your anti-virus or firewall software, or the software itself is damaged.
I agree with larrydls that you need to update the Service Pack version in your Outlook 2002. Here are the steps on how you can check the Service Pack (SP):
1. Inside your Outlook 2002 client, click Help and select About. 2. The “About Microsoft Outlook” window opens. The first line shows the version of the program you're using (for example, Microsoft® Outlook® 2002 (10.6515.6830) SP2). 3. It's that last part -- "SP2" in the example -- that tells you what version of the service pack (SP) you've got. If it shows anything other than SP3, you will need to download the latest Microsoft Office Service Pack by clicking here.
