Are Comcast and Xfinity email settings the same?
Yes, Comcast and Xfinity email settings are exactly the same. Xfinity is simply the current brand name for Comcast’s internet and email services, so the IMAP, POP3, and SMTP server names, ports, and security options you see on this page work for both Comcast and Xfinity email addresses.
Whether your address ends in @comcast.net or you access it via Xfinity Email (webmail.xfinity.com), use the same IMAP host (imap.comcast.net), POP3 host (pop3.comcast.net), and SMTP host (smtp.comcast.net) with SSL/TLS enabled on the recommended ports.

Update or Fix Comcast (Xfinity) Email Settings
If your Comcast (Xfinity) email is not working in Outlook, Apple Mail, Gmail, or another app, the problem is usually a small settings issue. Before you delete the account, go through this quick checklist and update your Comcast email settings where needed.
- Wrong port numbers: Make sure you are using Port 993 (IMAP) or 995 (POP3) for incoming mail and Port 587 (TLS) or 465 (SSL) for SMTP. Older guides that show non‑SSL ports are outdated.
- SSL/TLS disabled: In many clients, you must explicitly enable SSL or TLS/STARTTLS for both incoming and outgoing servers; without it, Comcast can reject or block connections.
- Authentication missing on SMTP: Always enable “My outgoing server (SMTP) requires authentication” and use the same username and password as your incoming server.
- Old server names: If your instructions show
mail.comcast.net, replace them with the current hosts: imap.comcast.net, pop3.comcast.net, and smtp.comcast.net. - Account or password issues: If everything looks correct but you still cannot sign in, log in to Xfinity webmail (webmail.xfinity.com) to confirm the password, reset it if needed, and then update it in your email app.
Once these items are fixed, most “Comcast email not working” and “Xfinity email not connecting” errors in Outlook, Apple Mail, Mailbird, or mobile email apps disappear without needing a full re‑setup.

Comcast (Xfinity) Email Settings FAQ
What are the Comcast email settings for iPhone?
On iPhone, go to Settings → Mail → Accounts → Add Account → Other → Add Mail Account, then enter your Comcast email and password. For the Incoming Mail Server, use imap.comcast.net with Port 993 and SSL enabled (IMAP is recommended). For the Outgoing Mail Server (SMTP), use smtp.comcast.net with Port 587, SSL or TLS enabled, authentication set to Password, and the same Comcast username and password.
What are the Comcast email settings for Outlook?
In Outlook, add a new account and choose manual setup or advanced options if needed. For IMAP, use imap.comcast.net on Port 993 with SSL/TLS, and smtp.comcast.net on Port 587 with TLS and “My outgoing server (SMTP) requires authentication” enabled. If you still use POP3, use pop3.comcast.net on Port 995 with SSL, but IMAP is recommended so your Comcast (Xfinity) email stays in sync across devices.
How do I change my Comcast email from POP3 to IMAP?
You can’t “convert” an existing POP3 account to IMAP in most clients, so the safest method is to add a new IMAP account and then move your old messages. First, add your Comcast account again in your email client and choose IMAP with imap.comcast.net (Port 993, SSL) and smtp.comcast.net (Port 587, TLS). After the new IMAP profile is working, drag any important emails from the old POP3 account folders into the new IMAP folders, then remove the POP3 account.
Why is my Xfinity (Comcast) email not working in my app?
Most “Xfinity email not working” issues in Outlook, Apple Mail, Mailbird, or mobile apps come from incorrect ports, disabled SSL/TLS, or missing SMTP authentication. First, verify you are using imap.comcast.net (993, SSL) or pop3.comcast.net (995, SSL) for incoming, and smtp.comcast.net (587, TLS or 465, SSL) for outgoing with authentication enabled. If settings are correct, check your password by signing in to Xfinity webmail, update it in the app if needed, and make sure your device, app, and network connection are up to date.
Are Comcast and Xfinity email settings the same?
Yes, Comcast and Xfinity email settings are the same. Xfinity is the brand name for Comcast’s internet and email services, so you can use the same IMAP, POP3, and SMTP server names, ports, and security options for @comcast.net addresses and Xfinity Email in any mail app.
What are the recommended Comcast IMAP, POP3, and SMTP ports?
For most users, Comcast recommends IMAP with Port 993 (SSL) for incoming and Port 587 (TLS/STARTTLS) for outgoing SMTP. POP3 uses Port 995 (SSL) for incoming mail, and SMTP can also use Port 465 (SSL) in some older clients. Always enable SSL/TLS (or STARTTLS) and make sure your email app is set to authenticate with your full Comcast email address and password when sending.
