Email Stopped Syncing
Comcast emails stopped syncing yesterday. This is happening on both the phone using a 3rd part app, and the computer using Outlook. When I try to repair the connection on Outlook, it says "We couldn't connect to the incoming (IMAP) server using the specified encryption method. Please check the incoming (IMAP) server encryption method and try again." My incoming server settings are: IMAP: imap.comcast.net PORT: 993 ENCRYPTION METHOD: SSL/TLS. Outgoing server settings are: SMTP: smtp.comcast.net Port: 587 ENCRYPTION METHOD: STARTTLS. I am able to access my web email and through the Xfinity app. No settings have been changed in the past month. I updated my 3rd party application on my phone to no avail. I installed Outlook on my phone and was unable to add the comcast email to the app and I get an Unable to login message. I also checked to ensure Third Part Access Security was enabled. Please help!

I have been experiencing the same issue since yesterday morning. I have done every step in the troubleshooting recommendations to no avail. In my case, I use apple mail on my phone and I haven't had an issue with that. The issue is just with Outlook on my PC.

The same is happening for me and my wife. I suspect the issue is with xfinity. They are moving everyone to yahoo email servers (although your email remains the same). Eventually you should get an invite saying your particular account has been transferred. I suspect that those of us still using the old email servers are going to continue to suffer until we are moved.

I am having the same issue as well. last synched message was at 9:07 AM Eastern on 12/8. Feels like a Monday AM patch that was not tested properly.

Hey folks,
We are looking into this.
Could you please share which Outlook version and operating system you're using?

I am having the same problem with email sync. Using latest release of Thunderbird and have had no problems whatsoever for years. My IMAP connection has been generating a server timeout error since Monday afternoon Dec 8th. I got a few updates Tuesday morning and nothing but timeout errors since then. I can successfully send emails from my Comcast email accounts but can't sync any of my incoming emails. I've checked all account configurations on Thunderbird, signed in Xfinity and checked emails through the browser with no errors or notifications, rebooted my router, and tried to access using a different computer and email client. None of these attempts was successful. Something is definitely wrong on the Xfinity server end. Please help.

Same issue here, no incoming email since Monday the 8th. Works fine on iPhone and iPad, but not on Outlook. I had two accounts setup. One I deleted and tried to recreate and that not working, getting the Unable to connect to IMAP server and the other, which I didn't delete gets the same message when I try to do a repair. Web portal works and have the setting to allow 3rd party email checked.

Same here on all my comcast.net email addresses using Edison Mail on my phones. I can connect using Outlook Classic on my laptop, but not on my mobile devices. Started yesterday after 1:36 AM (last email received on phones). When I try to reconnect my account(s), I'm getting an error message stating "[IMAP] A stable connection to the server could not be established."

I'll chime in as well; Outlook 2010. Having intermittent 'folder synchronization' issues and have never touched the connection configuration that has worked for years.

Using BlueMail on my phone I started having problems with email syncing and after a couple of days I fired up Thunderbird [which I had forgotten that I had set up sometime ago] and have had no problems since. No problems with email on Thunderbird on my Win 11 laptop.

Following as well. Using Outlook via Microsoft 365 and still on Windows 10. Any and all failures by Xfinity are certainly to be expected.
