Imap email client no longer syncing

My Imap email client no longer syncing incoming mail.  This is a 'Public chat post so that I can get a chat icon to DM this issue to Xfinity Email Support.  I have spent several hours and several days using the chat bot and phone support to no avail.  My email will occassionally sync incoming email then I get sync errors again.  The Xfinity webmail is poor client interface compared to Outlook and only a bandaid.  I am fairly certain that there may be others dealing with the same issue.  Please provide a DM link so this issue can get escalated.  Thank you.

Thank you, @user_vn3lzc for your time and patience. Your imap.comcast.net connection error (0x800CCC0E) in Outlook, while SMTP works, usually points to incorrect SSL/TLS setting (993 for IMAP, needing a fresh password after security changes, or a Comcast setting like Third party access being off, which you can fix in web you can fix in Xfinity webmail settings. Check IMAP is enabled in webmail, verify your Outlook ports (993/SSL for IMAP, 587/STARTTLS for SMTP), and ensure you're using an app-specific password if 2FA is on, as Comcast sometimes blocks direct logins.-Richard

Direct messaging isn't allowed until an official employee asks you to do so; it's against the Forum Guidelines and the Acceptable Use Policy to send anyone an unrequested DM/PM.  Also note, if you do send one without being asked to do so, it could possibly be ignored.
  
 Please always post your issue in public in the proper forum so that it can be addressed either by other customers or by an Official Employee.

I am having the same problem and have not been able to resolve it after multiple contact attempts. They just keep telling me the same steps over and over again that do not work to fix the issue. I can access the webmail, other email providers work fine on my phone so the issue is definitely Comcast syncing and using IMAP.

Good morning @user_8nli8o, and thanks for posting your issue to the Xfinity forums, I hope this message finds you well. I am sorry to hear that you are having issues with the email on your phone, but you have come to the right place for support. Have you tried deleting the email account from the phone and then adding it back on?

yes, I have tried all the normal suggestions. deleting, restarting, ensuring all the ports are correct (multiple times over different chat sessions) and nothing has worked.

user_8nli8o Let's take a closer look into the issue with your specific email on the phone.

Can you send us a direct message with your full name, name of account holder (if different), and service address please?

To send a "Direct Message" to Xfinity Support:

Click "Sign In" If necessary

Click the "Direct Messaging" icon (speech bubble)

Click the "New message" (pencil and paper) icon

The "To:" line prompts you to "Type the name of a person".

Instead, type "Xfinity Support" there

As you are typing a drop-down list appears. Select "Xfinity Support" from that list

An "Xfinity Support" graphic replaces the "To:" line

Type your message in the text area near the bottom of the window

Press Enter to send it
