I need a human to intervene to reset my IMAP authentication tokens (error 0x800CCC0E)

I have 4 Comcast email accounts that I maintain. My mailboxes are all returning error 0x800CCC0E in Outlook and failing IMAP connections on multiple devices. Webmail works. I need to have someone refresh the IMAP authentication token and reassign my mailboxed to a healthy IMAP cluster.

I cannot get through to someone in Xfinity Assistant because the bot just circles around and around and around and won't connect me with a human.

Good evening, and thank you for reaching out with your email concerns @techcommgeekmom, we appreciate it.

 

Refreshing IMAP authentication tokens or reassigning mailboxes to a different IMAP cluster is not something our team is able to perform from this platform. However, we’d be happy to work through some troubleshooting steps and, if needed, look into submitting a ticket for further investigation.

 

To help narrow this down, could you please confirm whether your email client settings match the configuration outlined here: Xfinity Email Client Setup.

 

Since webmail is working but IMAP is failing across multiple devices, it would also be helpful to know:

  • Whether you recently changed any account passwords
  • If Outlook prompts for credentials or simply returns the 0x800CCC0E error
  • Whether you can successfully log in to each mailbox through Xfinity webmail
