Comcast email is moving to Yahoo. You keep your address — here is how to move safely and fix Outlook
Xfinity is moving comcast.net mailboxes to Yahoo Mail, one mailbox at a time. Your address stays the same, but some things do not come across, and Outlook or your phone usually needs setting up again. Here is what to check before you accept, and what to do after. Rated 4.9 on Google.
- ● You keep your address
- ● Spot the real invite
- ● Fix Outlook afterwards
// THE SHORT ANSWER
What is happening to Comcast email
It is real. Xfinity began inviting comcast.net users to move to Yahoo Mail in June 2025, and the invitations are rolling out through 2026. Xfinity calls it an upgrade at no cost.
- You keep your @comcast.net address. It just lives on Yahoo’s system afterwards.
- Each mailbox moves separately. If your household has several comcast.net addresses, each one has to sign in and accept Yahoo’s terms.
- Afterwards you sign in at Yahoo (login.yahoo.com) with your full comcast.net address, not at Xfinity.
- There is no single deadline for everyone in Xfinity’s overview. Go by your own invitation.

// REAL OR SCAM?
How to tell the invitation is genuine
Scammers copy big email changes, so check before you click. Xfinity says genuine messages about the move come only from xfinity@updates.xfinity.com, or appear when you sign in securely at connect.xfinity.com. Xfinity will never ask you to reply with your password or other personal details, and the real process only sends you to Yahoo’s own site after you have signed in. Threatening, rush-or-lose-everything wording is a warning sign.
The safest habit: ignore links in the email itself, go to connect.xfinity.com yourself, sign in, and look for the invitation there (Xfinity: recognising the genuine invitation).
// BEFORE YOU ACCEPT
What does not come across, and what to save first
Xfinity lists what the move leaves behind:
- Settings, filters and forwarding — none of them carry over.
- Attachments over 25 MB do not move.
- Folders beyond 4,100 are merged, and folder names over 240 characters are cut short.
- Contacts beyond 10,000 are lost — and Yahoo adds that only contacts saved in your Address Book move, not addresses Comcast simply remembered.
So before you accept: save any large attachments you need; check the contacts you rely on are saved in your Address Book; write down your filters and where your mail forwards to; and if Outlook on your computer downloads your mail rather than syncing it (an older POP set-up), make a backup of Outlook’s data file first, because that may be the only copy of older messages.
// OUTLOOK AND YOUR PHONE
Outlook or your phone stopped working after the move
That is expected: your mailbox now sits on Yahoo’s servers, so apps still pointing at Comcast cannot find it. The fix is to set the account up again as Yahoo.
- Sign in at login.yahoo.com once with your full comcast.net address. If you get in, the move is complete.
- Back up before you remove anything. If Outlook downloaded your mail, export a copy first (File, Open & Export, Import/Export, Export to a file). If it synced (IMAP), your mail is safe on the server.
- Add the account again with your comcast.net address, and when Outlook or your phone asks for the provider, choose Yahoo.
- Setting it up by hand? Yahoo gives incoming imap.mail.yahoo.com, port 993, SSL/TLS, and outgoing smtp.mail.yahoo.com, port 587 or 465, SSL/TLS.
- Password refused? Create an app password on your Yahoo Account Security page (under App passwords) and use that in the app instead of your normal password.
Or skip Outlook altogether: our free Windows email program, just below, works with the same Yahoo settings and app password.
// ANOTHER WAY · OUR FREE EMAIL PROGRAM
Rather skip Outlook? Use our free app
On a Windows PC, our free Techies One Mail can read your comcast.net email on Yahoo alongside your other addresses in one window. If you decide to leave, it can copy the whole mailbox into Gmail, folder by folder.
- Free, from 365 Techies, the family IT firm that wrote this guide
- Signed by 365 Techies Ltd, and it tells you when there’s an update
- Big, clear buttons, and warnings about scam emails
- Your email goes straight between your PC and your provider: we never see it or your passwords
Type in Yahoo’s settings (imap.mail.yahoo.com, port 993; smtp.mail.yahoo.com, port 587) and use a Yahoo app password. Moving into Gmail needs a Google app password, which needs 2-Step Verification switching on first. See what it does, with pictures.

// FORWARDING
Your forwarding stopped
Forwarding does not survive the move — Xfinity says settings and forwarding rules do not carry over. Setting it up again on Yahoo is where it gets awkward: Yahoo’s help says automatic forwarding needs a paid Yahoo Mail Plus subscription and is not available everywhere. Its help does not mention an exception for comcast.net accounts, so check what your own Yahoo settings offer before paying for anything.
The free alternative is to read your comcast.net mail alongside your other email instead of forwarding it: add the account to the Gmail app on your phone, or to Outlook or Thunderbird on your computer. One thing not to set up now is Gmail on the web “checking” your Comcast mail — Google is removing that in January 2027 (what is changing in Gmail).
// STAY OR MOVE?
Keep the Comcast address on Yahoo, or move to your own?
Staying is the least work: same address, no cost according to Xfinity, and everyone who knows your address keeps reaching you.
Moving to Gmail or Outlook.com gives you an address that is not tied to your internet provider, which is worth thinking about if you might ever leave Xfinity. But it is a new address: you copy your old mail across, tell people, and change it on your bank, insurance, utilities and other accounts while the comcast.net address still receives their emails.
If you do move, our free Techies One Mail for Windows PCs can copy the whole comcast.net mailbox into Gmail for you, folder by folder.
Our view: accept the move to keep things working, then decide about a new address calmly, without a deadline over your head.

// GOOD QUESTIONS
Frequently asked
Is the Comcast email move to Yahoo real or a scam?
It is real: Xfinity began inviting comcast.net users in June 2025 and continues through 2026. But scammers copy it. Genuine messages come only from xfinity@updates.xfinity.com or appear when you sign in at connect.xfinity.com, and Xfinity never asks for your password by email.
Do I keep my comcast.net email address?
Yes. Your @comcast.net address stays the same; afterwards you sign in to it at Yahoo with the full address.
Will all my emails and contacts move?
Most will, with exceptions Xfinity lists: settings, filters and forwarding do not carry over; attachments over 25 MB do not move; folders beyond 4,100 are merged; contacts beyond 10,000 are lost. Yahoo adds that only contacts saved in your Address Book move.
Why did Outlook stop working with my Comcast email?
Your mailbox moved to Yahoo’s servers. Sign in once at login.yahoo.com, back up any mail Outlook downloaded, then add the account again choosing Yahoo as the provider. If your password is refused, create a Yahoo app password.
Is there a deadline to accept the move?
Xfinity’s overview gives no single deadline for everyone; invitations roll out through 2026. Go by the dates in your own invitation from xfinity@updates.xfinity.com.
