Your email might not work if you are using an outdated version of your web browser. Check if your browser is supported by Comcast and if it is then try clearing out the cookies and caches before you try again. If you continue to face the problem on your existing browser then try accessing your emails on a different web browser.
If your web browser and internet connection are in perfect condition then there might be something wrong with your Xfinity email settings. You can check whether you have maxed out the daily limit of sending/receiving emails or not and see if there is enough space for smooth functioning. You can also see your other folders like trash/junk and find out whether your emails are getting redirected to them or not. Also, there is no harm in cross-checking the receiver's email address because if you have entered it wrong then you won't be able to send them any emails quite evidently.
