Solution 1: Fix Internet Issues

A poor or unstable internet connection can induce an endless number of issues with your Comcast email account and make it hard for you to work with Comcast configured on Outlook. Therefore, the troubleshooting should begin by checking the internet issues and fixing issues, if there are any. To check the network strength, you can perform a network speed test or simply open a random webpage and see how long it takes to open it. With a fast and proper network supply, you won’t face difficulty in opening web pages, whereas a slow network will provide a sluggish response. 

If you come to know that your network needs some fixation, you should try restarting your router and modem or simply contact your Internet Service Provider for help.

Solution 2: Check Comcast Server Status

If your network strength is fine, still Comcast isn’t working on Outlook, it might be due to the fact that Comcast is down in your area. The Comcast Outage can keep you from accessing the Comcast services, whether you are using it on your browser or with a third-party email client. To check Comcast server status, you can use third-party sites such as https://downdetector.com/status/comcast-xfinity/

So, when you are not able to access Comcast due to a service outage, you are suggested to wait for 12-24 hours before performing any other troubleshooting workaround. 

Solution 3: Check General Comcast Email Settings

When you are not able to perform a specific task on your Comcast email account with Outlook, make sure that you are not making a silly mistake and following the general rules of the Comcast email account.

So, make sure you keep an eye on the following things:

  1. If you are unable to send emails from Comcast make sure you haven’t crossed the daily sending limit.
  2. If you can’t find a specific incoming email, check the Trash or Spam folder.
  3. Check your block list and make sure that the recipient is not blocked if you are unable to receive some or a few emails.
  4. Also, make sure that you are not blocked by the recipient if you are not able to send emails
