        "content": "If your Comcast.net email has moved to Yahoo Mail, here are the server addresses and port settings you\u2019ll want in order to get Outlook (Classic for Windows) working properly. These are based on Yahoo\u2019s official documentation and what people who\u2019ve made the switch report, as of mid-2026.  \n\n---\n\n## \u2699\ufe0f Basic Steps Before You Change Settings\n\n1. Make sure you\u2019ve **accepted Yahoo\u2019s Terms of Service** for your Comcast.net email when prompted. ([help.yahoo.com](https://help.yahoo.com/kb/SLN36803.html?utm_source=openai))  \n2. Sign in at **login.yahoo.com** using your full Comcast.net address (including \u201c@comcast.net\u201d) and your existing password. ([help.yahoo.com](https://help.yahoo.com/kb/SLN36803.html?utm_source=openai))  \n3. If Outlook asks for support with access, you may need to **generate an app password** via Yahoo\u2019s Account Security \u2192 App Password section. Use that in Outlook instead of your normal password. ([help.yahoo.com](https://help.yahoo.com/kb/SLN36803.html?utm_source=openai))  \n\n---\n\n## \ud83d\udce7 Outlook Setup: Server & Port Details\n\nUse these settings in Outlook for both incoming and outgoing servers once your Comcast.net account is fully migrated to Yahoo Mail.\n\n| Connection Type | Server Address | Port | Encryption / Security | Username |\n|---|---|---|---|---|\n| **IMAP (Incoming)** | `imap.mail.yahoo.com` | **993** | SSL/TLS | Your full Comcast.net email address (e.g., user@comcast.net) with your app password if required. ([en-global.help.yahoo.com](https://en-global.help.yahoo.com/kb/new-yahoo-mail/manually-download-yahoo-emails-sln28681.html?utm_source=openai)) |\n| **SMTP (Outgoing)** | `smtp.mail.yahoo.com` | **465** (SSL) or **587** (STARTTLS / TLS) | SSL/TLS or STARTTLS depending on port | Same credentials: full Comcast.net address + app password (if using) ([en-global.help.yahoo.com](https://en-global.help.yahoo.com/kb/new-yahoo-mail/manually-download-yahoo-emails-sln28681.html?utm_source=openai)) |\n\n---\n\n## \ud83d\udd01 What About the Old Comcast/Xfinity Servers?\n\nBefore your email was migrated, the Comcast/Xfinity IMAP/SMTP servers looked like this:\n\n- Incoming (IMAP): `imap.comcast.net`, port **993**, SSL/TLS ([support.postbox-inc.com](https://support.postbox-inc.com/hc/en-us/articles/115002079153-Email-Settings-for-Comcast-XFINITY?utm_source=openai))  \n- Outgoing (SMTP): `smtp.comcast.net`, port **587** (or **465**) with STARTTLS or SSL/TLS depending on your setup ([support.postbox-inc.com](https://support.postbox-inc.com/hc/en-us/articles/115002079153-Email-Settings-for-Comcast-XFINITY?utm_source=openai))  \n\nBut once your account is **moved to Yahoo Mail**, you should use Yahoo\u2019s servers listed above for both incoming and outgoing connections. ([help.yahoo.com](https://help.yahoo.com/kb/SLN36803.html?utm_source=openai))  \n\n---\n\n## \u26a0\ufe0f Common Pitfalls\n\n- Using your Comcast.net **password** instead of an **app password** can lead to authentication failures. ([help.yahoo.com](https://help.yahoo.com/kb/SLN36803.html?utm_source=openai))  \n- Mistyping the username: it should still be *yourname@comcast.net* even after migration\u2014not a @yahoo.com address. ([reddit.com](https://www.reddit.com/r/Comcast_Xfinity/comments/1ohtcy2/has_anyone_transferred_their_comcast_email_to/?utm_source=openai))  \n- Encryption mismatch: if you use the wrong port/encryption pairing (for example, SSL when TLS is expected), Outlook may reject the connection. ([reddit.com](https://www.reddit.com/r/Comcast_Xfinity/comments/1p6hroc/after_switching_email_over_to_yahoo/?utm_source=openai))  \n\n---\n\nIf you like, I can walk you through the exact steps in Outlook Classic (with screenshots, if available) so you can update the settings without guesswork. Want me to send those too?"
