Outlook connection to email server issues

Today, my Outlook suddenly got disconnected from my email server. Hoping it wasn't during something I did setting up my Norton 360 software. Now I can't get Outlook to connect to my email server - I've tried everything. I can go to the Xfinity site on a web browser and log into my email account, so I know I am entering the correct email/password, but when I try to fix the Outlook connection for that email account, nothing works. Worked great for about 20 years, until today.

    Hi!

    If the problem occurred after installing Norton, it might have blocked it for some reason. I have encountered similar issues with other antivirus programs. You can try temporarily uninstalling Norton, restarting your computer, and attempting to log in with your account.


    If the problem persists, try adding your account this way:

    1. Press Windows + R > type control > Under View By, select Large Icons > Click on Mail (Microsoft Outlook).
    2. Click on Add Account (Or Show Profiles > Add Profile if there is no profile).
    3. Select Manual setup or additional server types > POP or IMAP > Fill in the requested fields with your account information.
    • You should be able to obtain all this information from your email provider.
    1. Click on More Settings > Fill in more information in Outgoing Server and Advanced.
    2. Click OK > Next.

    Some email providers require an application code instead of a password. If the problem persists, try generating an application code and using it in place of the password.
