Question

Outlook no longer connecting to my comcast email account

Kathleen Dinndorf 0

Starting with the Outlook update last week, Outlook can no longer connect to the Comcast IMAP or POP servers for me to receive my comcast.net email. I can send outgoing email. The problem is not on the Comcast side as other email clients can connect to my email just fine. It is an issue both with Outlook withing Microsoft 365 and with the Outlook mobile app on my phone. Has this problem been reported, and is there a fix forthcoming?

If Outlook is no longer connecting to your Comcast email account using IMAP or POP, there are a few steps you can take to troubleshoot the issue:

Check for Software Updates: Ensure that your Outlook client is up to date. Running outdated software can lead to connectivity issues. You can run Windows Update to check for the latest updates for Outlook and other Microsoft 365 applications.
Enable Basic Authentication: If your organization has disabled Basic authentication, this could prevent Outlook from connecting to your Comcast account using POP or IMAP. You may need to enable Basic authentication temporarily for these protocols until a more permanent solution is found.
Run Microsoft 365 Diagnostics: You can run the Microsoft 365 Diagnostics tool to check for connectivity issues. This tool performs automated checks and provides possible solutions.
Check Email Settings: Verify that your email settings in Outlook are correct. Ensure that the server settings for IMAP or POP are configured properly according to Comcast's specifications.
Test with Outlook on the Web: If you can access your email through a web browser, this indicates that the issue may be specific to the Outlook application.
Contact Support: If the problem persists, consider reaching out to Microsoft support for assistance, as they may have more information on whether this is a widespread issue and if a fix is forthcoming.

These steps should help you identify and potentially resolve the connectivity issue with your Comcast email account in Outlook.
