Equipped with all the amazing features, AT&T is never expected to go down. However, not all days are bright and the same happens with AT&T when you realize it is not working with Outlook. 

This has been reported by most of the users who tried to access ‘att.net email’ through Outlook and found it not working. 


So here we are going to discuss this prevalent AT&T issue and what all help you can expect when att email is not working after configuring it to Outlook.

    2. There can be some settings or add-ons that are interrupting with Outlook and this could be one major reason due to which your ATT email account is not working with MS Outlook. Start Outlook in safe mode to check if they are the culprit using the steps listed below:

    • By pressing the Windows key and R, the ‘Run’ dialog box will open. Type ‘Outlook/safe’ in the given space and then click ‘Ok’.
    Go to Windows key and R, type the Outlook/safe and click on OK
    • Click on ‘Ok’ in the new window and Outlook will start; check if the issue persists.
    • If you got rid of the error, that means the settings or add-ons were causing the issue.

  2. Check the AT&T-Outlook Configuration

    3. If you haven’t configured AT&T email in Outlook properly, you are going to face glitches, and to fix this, you will need to enter the correct AT&T mail settings. Here is how you can fix the configuration if att.net email is not working with Outlook:

    • In the ‘Email’ tab, click on the ‘New’ option.
    • Switch on the ‘Server Settings’; press ‘Next’.
    • Select the ‘Internet Email Addresses’ and then click on ‘Next’; enter the following information in the given fields:

    User Name: Full Name.

    Email Address: AT&T Email Address

    • For ‘Type of Account’, select ‘IMAP’ or ‘POP’ and then enter the given information:
    • AT&T IMAP Settings for Outlook

      • Incoming Email Server: imap.mail.att.net

      Incoming Port: 993

      Outgoing Email Server: smtp.mail.att.net

      Outgoing Port: 465

    • POP Settings for Outlook

      • Incoming Email Server: inbound.att.net

      Incoming Port: 995

    • Under the ‘Login Information’ tab

      • Email Address: ATT email ID/User ID

    The AT&T email settings for outlook 2016, 2019, and other versions are almost the same.

    • Click on ‘Test Account Settings’ and if you find everything correct, click on ‘Next’ and then click on ‘Finish’ to save the AT&T email account settings for Outlook. 
    • Thereafter, you can simply log in to your AT&T email account on Outlook by entering all login details.

  3. Check the Antivirus

    4. Antivirus or Windows firewall works to protect your device from malware and virus, however, sometimes they can also interfere with other software and your email account. So whenever you experience any issues while using AT&T on Outlook or it is not working, you should temporarily disable the antivirus or firewall and then check if it helps.

  4. Remove and Re-add your Email Profile

    5. If your att.net email is not working, be it 2013, 2016, or 2019, you can try this method as it has proved to be helpful. So to remove your AT&T email account from Outlook here is what you need to do:

    • Go to the ‘Files’ tab in Outlook and click on ‘Account Settings’.
    • Then click on the option ‘Manage Profiles’ and you will see the option ‘Show profiles’; click on that.
    • Select your AT&T account that you want to remove and click on the ‘Remove’ button.

    Re-configure your AT&T account now and then check if it fixed the error.

  5. Switch to IMAP

    6. IMAP and POP are the two types of accounts; the former being the latest. IMAP offers certain features that are not there in POP. It lets you sync your emails across all your devices and that is the reason most of the email services are shifting to IMAP in 2020; POP is slowly going outdated. 

    So, if att.net email is not working, you can try switching to POP from IMAP. You can make the changes in the account settings of your Outlook account and after switching to an IMAP account from POP, the issue may disappear. 

  6. Use Google DNS

    • On the taskbar, click on the network icon and select your network.
    • Then select ‘Change adapter options’
    Click on change adapter option
    • You will see the list of all the network connections available on your PC and then right-click your network and choose ‘Properties’.
    See the network connections and click on propeties
    • Now, select ‘Internet Protocol Version 4 (TCP/IP4)’ and then click on the ‘Properties’ option.
    Select Internet Protocol Version 4 (TCP/IP4)’ and press on Propeties
    • Next, choose ‘Use the following DNS server addresses’ and type 8.8.8.8 as the Preferred and 8.8.4.4 as Alternate DNS server; press ‘Save’.
    Use the following DNS server addresses and press on save

  7. Try Using a Different Email Client

If nothing helps you out and you are still wondering why my AT&T email is not working, you can try using the webmail version as a temporary solution. You will not need to configure the account and can simply log in to AT&T mail using the username and password to check your emails. Make sure att.net email is not down and the servers are working fine. 

That’s all you can try to fix your AT&T account with Outlook.
