Comcast/Xfinity requires an extra layer of authorization before you can add your account to Edison Mail. Please try following the steps in this article before adding your account to our app: https://www.xfinity.com/support/articles/third-party-email-access
How to Update Email Security Settings
- Open Xfinity Connect
- In the top-right corner, click the Gear icon, then select Settings
- Click Security
- Check the box under Third Party Access Security to allow third-party programs (ie: Edison Mail) access to your Xfinity/Comcast Connect email.
After you've enabled/allowed third-party access as detailed in the article above, were you able to add your Comcast/Xfinity account to the Edison Mail app? If not, this indicates that Comcast has likely blocked your IP address/our app from accessing your email account temporarily. We'd recommend reading the following article, as it contains information about their error codes and most importantly, instructions for submitting an IP block list removal request at the bottom of the page ("How do I get my IP block removed?"): http://postmaster.comcast.net/smtp-error-codes.php
You can also try waiting about a day or so to see if the issue resolves on its own, or contacting Comcast customer support for assistance.
