Steve Jackson 10

I can't seem to get my Comcast email to work with Outlook. It was working fine up to a couple of days ago but will now work on any device(Windows PC, iPhone and iPad). Will work with web browser.

Hi Steve Jackson, I know how stressful it can be when something that worked perfectly just a few days ago suddenly stops working across all your devices.

To fix Comcast email issues in Outlook enable third party access in your Comcast settings confirm IMAP/SMTP details clear Outlook RoamCache use an app password if required check SSL and VPN settings re add the account on iPhone/iPad after enabling access and update both Outlook and your device.

When Outlook fails to connect to your Comcast email do you see an error message like Cannot connect to server or does it keep asking for your password and have you recently changed any Comcast security settings or passwords?

Best regards

I have the same problem. I did not make any changes to my Outlook or Comcast accounts before the problem began. I have enabled third pary access, cleared RoamCache, checked SSL and VPN settings, removed and tried to re-install accounts in Outlook and updated Outlook, Windows and Android to ensure my phone and laptop software are current. NOTHING has worked. Please help.

I'm having the same issue on multiple devices. Outlook keeps asking for my password. Outlook can't sign into Comcast (but does get my other emails). I can get into Comcast with my password if I go directly online or via Xfinity app so I know the password is correct.

I have the same issue on PC, iphone and ipad. I changed password, enabled third party access, and still nothing. And I can't get technical support from Geek Squad - they said to contact comcast

Check if your Comcast email has been migrated to Yahoo?

Go to https://login.yahoo.com/
Enter your full Comcast email and [Next].
You will get a "Sorry, we don't recognize this email" if you have not been migrated yet.

Starting in June 2025, customers with a comcast.net email will be invited to upgrade their email account to Yahoo Mail for a better email experience at no extra cost. Invitations will roll out gradually through 2026, and when the time comes, you’ll see yours in your inbox or when you securely sign in to connect.xfinity.com.

Use the Comcast Web Mail interface to check if you have received a notification.

I have migrated two of three Xfinity accounts to Yahoo. I've managed to setup one of them on Outlook for Android, but the other refuses to connect. I keep getting "Unable to login. Please check your email and password and try again." I know the server info is correct and the login name & password are correct.

1 -- Just to be sure, you CAN logon to https://login.yahoo.com/ using your full Comcast email and password? And you accepted the Yahoo Terms and Conditions? But you can NOT logon to https://www.xfinity.com/email any more?

2 -- Did you try letting Outlook for Android do an "auto discovery"? i.e. Remove the account from Outlook. And when you add it back, just give Outlook your Comcast email and password. Don't try to do any manual protocol or server settings.

If none of this helps, come back and we'll try something else.
