To better protect your Xfinity email username and password from being compromised, third-party email applications (Outlook, Apple Mail, Thunderbird, etc.) through a non-encrypted connection are now required to use a secure outgoing mail server. If you use a third-party email application, you’ll need to configure your outgoing mail server port to 465 or 587, and update the encryption settings of your outgoing mail server from non-encrypted to encrypted settings. If you don't adjust your email settings, you'll still receive emails, but not be able to send emails after the non-encrypted email settings are blocked.     Outlook 2007, 2010, 2013, 2016 or 2019 Open Outlook.

Frequently Asked Questions Why do I need to change my non-encrypted outgoing email server settings? We're blocking non-encrypted outgoing email server settings to protect your Xfinity email username and password. No accounts have been compromised; however, this change provides you and your personal information with the best level of protection possible. Will changing the email settings affect how I get emails or manage my mailbox? No. Changing your outgoing email settings will not impact the way your emails are received or managed. What will happen if I don't update my port settings? If you don't adjust your settings in your third-party email application, you can still receive emails. But, you can't send emails after the non-encrypted email settings are blocked. When non-encrypted email settings are blocked, you'll get an error message when you try to send an email. When do I need to make these updates? Please update your third-party email application settings before September 24, 2019, and no later than October 1, 2019.

Ready to get started using your Comcast email? No problem. Our web-based  Xfinity Connect page  and  app  come set up and ready for you to use. But if you prefer using an email program instead, these settings will have you up and running in no time! If you have questions about your specific program or email client, we've got you covered. Just head to the  links section  and pick your program. To ensure the security of our network and customers, we no longer support the use of port 25 for sending email. If you use an older email client (Outlook Express, Outlook, Mac Mail, etc.), this might impact your ability to send email.  Learn more about port 25 .   Email Settings When your program asks you to set up your email, use these settings to connect your Comcast email: Incoming Mail Server Name:   imap.comcast.net Incoming Mail Server Port Number:   993 with SSL ON If the Mail Client lets you select an authentication method, choose   STARTTLS. If Needed:   143 with SSL ON Outgoing Mail Server Name:   smtp.comcast.net Outgoing Mail Server Port Number:   587 (SMTP) If Needed:   465 (SMTPS) Encryption:   TLS   (use   SSL   if   TLS   isn't shown.) Authentication: Type in your   Comcast username and password   Email Setup: Port Numbers and POP vs. IMAP When you're setting up your email account, your program will ask for some information about email "protocols." Here are a couple of things to know as part of your set-up: Port Numbers:  Your email port is how email moves from one email server to another. To protect your security and help prevent spam, we no longer support port 25. If you're using an older email program like Outlook Express, Outlook, or Mac Mail, you may have trouble sending email.  Learn more about port 25 . POP vs. IMAP:  POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different ways to get email in your email program.  We recommend using IMAP  for your Comcast email. POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device. IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device. With IMAP, the email changes you make on one device, like your smartphone, are reflected on your other devices, like your laptop. But if you'd still like to use POP, use these settings in your email program: Incoming Mail Server Name:   pop3.comcast.net Incoming Mail Server Port Number:   995 (POP3 with SSL) Incoming Mail Server Port 110 is no longer supported. Make sure to use port 995 instead. You can check this in your email program's   Settings,   Advanced Settings   or   Preferences   menu.

Differences between and Primary and Secondary users and how to manage them

If you want to give other members of your household access to your master Xfinity account, you can create up to six distinct usernames online. By adding a user, you allow him or her access to manage your Xfinity services (billing, account information, etc.) and access your subscriptions such as X1 TV viewing. You can adjust individual permissions. Each account user must reside at the premises where the Xfinity services are provided.      Add or Invite a New User to Your Account Sign in to   My Account   as the primary user. Click or touch the   Users   tab at the top of the page. Underneath the current user portals, select the option to   Add a New User. Select the   Create credentials   option and click   Continue. Alternately, choose   Send email invitation   and follow the instructions below. Fill out the form with the new user's details, including their first and last name, a unique username and a password. Click or touch   Continue. **Note**:   Passwords must be 8-16 characters with no spaces and contain at least one letter and one number or special character. Keep billing permissions toggled to   Off   to grant basic account access. Toggle billing permissions to   On   to allow the new user access to view, manage and pay your bill. After making a selection, click   Continue. Set up a secret question and answer for username/password recovery purposes, and then click   Create Account. A confirmation message will appear, showing you the newly added user along with their username and newly created email address.     Invite a New User to Your Account via Email In addition to creating an account for the new user, you can add a new username via an email invitation, which will allow the user to create their own Xfinity account. Sign into   My Account   as the primary user. Click the   Users   tab at the top of the page. Underneath the list of current users, click   Add A New User. Select   Send email invitation   and click or touch   Continue. Fill out the form with the new user's details, including their first and last name and email address. Click or touch   Continue.

To give the new user permission to view, manage or pay your bill, toggle billing permissions to   On   and click   Invite User. A confirmation message will appear, and the new user will receive an email invitation to create their account. Next, the new user will need to accept their invitation via text message or by entering the household's ZIP code. **Note**:   After entering their mobile phone number, the new user will have 15 minutes to enter the verification code that they received via text message. Once the invited user confirms their account by text or by entering their ZIP code, they will be prompted to set up their username, password and password recovery method. Once the forms are completed, the new user account will be created. **Note**:   If no action is taken within 72 hours of the invitation being sent, the primary user of the account must make a new invitation request.        How to Suspend or Remove a User - My Account Help Suspending a user:   All Comcast access and services for this user will be suspended for a 90-day period. You may reactivate the user at any time during this period. If you do not reactivate the account, it will be subject to deletion. Removing a user:   This permanently deletes a secondary user, and all settings and preferences for this user will be erased. When you delete a username, you'll likely lose emails, voicemails, and other information associated with the username.

To better protect email and Xfinity credentials from being compromised, customers who use a third party email application (Outlook, Apple Mail, Thunderbird, etc.) through a POP connection are now required to use a secure mail server and can no longer utilize POP Port 110. While POP will still be supported, customers should ensure that their email application is set up through the secure Port 995. If your application is configured through Port 110, you’ll need to make a few updates to continue to use your Xfinity email.

We are blocking this port because it is not encrypted and may leave your email account information vulnerable to being compromised. No accounts have been compromised; however, this change will help to provide you and your personal information with the best level of protection possible. Can I still access my email through POP? Yes. Port 995 with SSL is secure and is the recommended port for POP. You can update your Incoming Mail Server Port to 995 with SSL to continue to receive mail without any change to your experience. Will changing the email settings affect how I receive emails or manage my mailbox? We recommend that you switch from POP Port 110 to Port 995, which will not affect how you receive emails or manage your mailbox. If you wish to change from POP to IMAP, please move any emails or folders that you wish to save into your new IMAP account  before   deleting the POP account to prevent any impact to your experience. Please see  Switching from POP to IMAP  for additional details. What will happen if I do not update my port settings? After access to the port is blocked, you will receive an error message in your third-party email application when attempting to access your Xfinity email. You will continue to be able to access your email through Xfinity Connect webmail, the Xfinity Connect app or any email application without any impact. When do I need to make these updates? Please update your settings prior to December 2018 to ensure that you can continue using email with your third-party email application after Port 110 is blocked. If you update your settings after port access has been blocked, any email received while blocked will appear in your inbox once you have updated your port settings.       Learn more about updating your Xfinity Email POP Port Settings
