Gmail's Mail Fetcher utility makes it easy in many cases to transfer email from your old AT&T account into your Gmail account. The only catch is that you must have created your AT&T account on or before June 11, 2011; otherwise, AT&T won't give you the POP3 server access required to make the direct transfer.

Step 1

Sign in to your Gmail account, click the gear icon on the toolbar and select "Settings."

Step 2

Select the "Accounts" tab, and then click "Add a POP3 Mail Account You Own" in the Check Mail From Other Accounts section.

Step 3

Enter your AT&T email address, click "Next Step," and then enter your AT&T password.

Step 4

Enter "inbound.att.net" in the POP Server field, and change the Port setting to "995".

Step 5

Check the box next to "Leave a Copy of Retrieved Messages on the Server" to prevent Gmail from deleting the emails.

Step 6

Check the box next to "Always Use a Secure Connection (SSL) When Retrieving Mail."

Step 7

Check the box next to "Label Incoming Messages" if you want Gmail to mark the messages as having come from your AT&T account. You will be able to access the messages from a separate folder in Gmail if you select this option.

Step 8

Check box next to "Archive Incoming Messages" if you want to prevent the AT&T messages from appearing in your Gmail inbox.

Step 9

Click "Add Account" to begin transferring your AT&T mail to Gmail. The process takes several minutes or longer, depending on how much mail you have in your AT&T account.
