Comcast Email Settings - How to Configure SMTP and IMAP & POP3 Outlook Server Settings

The instructions contained in this article only apply to users who have already configured their Xfinity email accounts via POP.

In addition, this guide assumes that while setting up your email through POP, you chose not to retain emails in the server after downloading them to the email client

Comcast is a popular Internet Serv,ice Provider (ISP) in the United States that provides free email accounts to those who subscribe through the ISP. 

A common task that Comcast subscribers face is configuring their email program to download and send email using their Comcast email account.

Comcast email su.pp.orts all major email programs on the market and can be used for secure and non-secure POP3 email. Email Settings (Configuration updated)

To configure an email client to use Comcast email (, the following settings should be used for sending and receiving email:

•    Incoming Mail Server Name:

•    Incoming Mail Server Port No.:

    o    Recommended: 993 with SSL ON

    o    Only if Needed: 143 with SSL ON

•    Outgoing Mail Server Name:

•    Outgoing Mail Server Port No.:

    o    Recommended: 587 (SMTP)

    o    Only if Needed: 465 (SMTPS)

•    SSL Encryption: checked

•    Authentication: Xfinity username and password required

Using POP3 to retrieve email will cause a less than optimal experience, especially when you use multiple devices to check your email. We strongly recommend IMAP over POP since this will keep your emails in sync across different devices. If you do need to use POP due to any reason, you can use the following connection information:

•    Incoming Mail Server Name:

•    Incoming Mail Server Port 995 (POP3 With SSL)

Please note that Incoming Mail Server Port 110 will no longer be su.pp.orted. If you wish to continue to use POP, please update your configurations to Port 995. To do so, find your email application's Settings or Preferences section on the device that you use to access your Comcast email account. Note that depending on your email application, port configurations may be located under advanced settings.

Important Prerequisite

1.    Select File, and then Account Settings.

2.    Select your Comcast email account, and then click Change

3.    Confirm that the account type is POP, and then click More Settings.

4.    Click the Advanced tab, and check the Leave a copy of messages on the server checkbox. Then, click OK.

Switching from POP3 to IMAP

1.    Select File, and then Add Accounts.

2.    In the Add Account window, enter your Comcast email address and password. Then, click Next.

3.    By default, the account will be configured via IMAP, so simply click Finish.

Moving Emails from the POP to IMAP Profile

If the option to delete emails from the server was initially chosen during POP account configuration, emails would have been deleted from the mail server

 as they were downloaded to the email client, so the newly configured IMAP account will not contain these emails.

To avoid losing these emails during the switch from POP to IMAP, you must select the emails contained in the various folders (inbox, sub folders,

trash or sent items) on your POP account, and drag and drop them into the respective folder within your newly configured IMAP account. To be safe,

you can also move and store these emails in an external folder.
