Out of the blue, I can’t send or receive email. My settings are all correct as well as the ports? Anyone have any idea? Comcast is blaming Microsoft.

    If your IP address is causing mail to be blocked (Comcast’s “block” list)http://postmaster.comcast.net/
    Comcast sometimes blocks access to SMTP port 25 if it thinks that a computer is sending spam

    Server Information

    Account Type: POP3
    Incoming mail server: mail.comcast.net
    Outgoing mail server (SMTP): smtp.comcast.net

    Logon Information:

    User Name: my user name
    Password: my password

    Click More Settings > Outgoing Server, and check these boxes:

    My outgoing server (SMTP) requires authentication
    Use same settings as my incoming mail server

    Click More Settings > Advanced

    Server Port Numbers

    Incoming server (POP3): 110
    Outgoing server (SMTP): 587

    Use the following type of encrypted connection: None

    Hello, What version of outlook are you using?  Do you get any error messages? If you do, what are they?  Are you sure there hasn’t been any changes in comcast?  Most times this happens due to misconfiguration.  It is also good to check settings for antivirus/firewalls.  While it is not recommended, you could try disabling your antivirus/firewall, one at the time to check if you are able to send/receive emails. 

    If the above doesn’t help, you could try creating a new profile:
