    If New Outlook is not syncing with your Comcast email account, here are some troubleshooting steps you can try:

    1. Check Internet Connection: Ensure that your device is connected to the internet.
    2. Account Settings: Double-check your account settings in New Outlook to ensure that the incoming and outgoing server settings for Comcast are correct.
    3. Clear Cache: Sometimes, clearing the cache can help resolve syncing issues. You can do this by going to the settings in New Outlook and finding the option to clear cache or reset the app.
    4. Re-add Account: Since you've already deleted the email account, try adding it again. Make sure to enter the correct credentials and server settings.
    5. Firewall and Security Software: Ensure that your firewall or any security software is not blocking New Outlook from accessing the internet. Check the settings to allow New Outlook through the firewall.
    6. Update New Outlook: Make sure that you are using the latest version of New Outlook. Check for updates and install any available.
    7. Reinstall New Outlook: If the above steps do not work, you may want to completely uninstall New Outlook and then reinstall it to see if that resolves the issue.

    If these steps do not resolve the syncing issue, you may want to consult the support documentation or contact support for further assistance.

    Hi Jeff, I get how inconvenient that can be when email stops syncing out of the blue. The issue usually comes from changes in Comcast’s security settings or how New Outlook handles older email protocols. Comcast often requires an app password or OAuth authentication now, and if Outlook is still using basic authentication, it won’t connect. Let’s check a couple of things: when you re-added the account, did you use the “Add account” option and enter your Comcast credentials, or did it ask for an app password? Also, can you confirm if you’re on the latest version of New Outlook? If not, update first. If you already did that, try generating an app password in your Comcast account settings and use that instead of your regular password. Let me know what happens when you try that. Does it still fail to connect or give an error?

    I have tried all this. I just logged into my Comcast email and forwarded emails to my Gmail account and it works perfectly. I am able to add back the Comcast email in new outlook so long as the forward option in Comcast is on. If I shut off the forward option, the email stops syncing entirely.
