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!

None of our Comcast accounts have been able to sync in Outlook on PC or Android phones since 12/3/25.

I started experiencing the same problem last week as well. I got a message when I opened my iPhone email app telling me to sign in to my xfinity email server which I did. I can send and receive emails in my iPhone email app but it’s not syncing with my xfinity web email like it supposed to. Additionally, my folders have disappeared from the iPhone email app but I can see them in the xfinity web email. Has a resolution been determined?

Hi there, @user_5d8rme! Thank you for taking the time out of your day to reach out about the email syncing. I understand that can be a frustrating thing to go through. Some of our other users have reported that this is resolved now. Is this working for you now or do you still need assistance?

I'm back to not syncing again ... this is so disappointing. I've been a Comcast customer for more than 20 years and I've never run into problems like this. My Comcast stopped syncing Monday the 8th and Comcast finally got things resolved on Thursday the 11th. Now I get up his morning and my email is back to getting server timeouts on both of my Comcast email addresses. Hopefully, the engineers have discovered what is causing these problems and can get this fixed quickly.

Hello,

My email stopped syncing again as well. I am unable to send or receive on my computer using Outlook or on my phone using Edison Mail. This is the same issue I had on Monday, which was resolved for a day or two. Please help!

Went on a Vacation the day the email came back on line. I got back yesterday and it worked for part of the day and now it's no longer working. Same message, can't connect to the IMAP server. Doesn't work on Desktop Outlook, works sometime on iPhone. Can access mail via website. As before, I'm confident that enough customers will have to report this before Xfinity/Comcast will believe it's actually happening and take some action to fix the issue. It's almost the weekend, so I'd be pleasantly surprised if we see a fix prior to the first of next week.

Hey folks,

I'm going to ask that if you're seeing an issue today (Dec 18th, 2025), could you please DM me some details about your configuration? (Do NOT put it in a reply here, it will get flagged by a moderator for containing private information)

UserID(s) Impacted:
ISP or Mobile Carrier:
Email Client:
Operating System:

IP Addresses from whatismyipaddress.com (IPv4 and IPv6):
Knowningly using VPN or other Anonymity service: Y/N
Other details:

The "other details" could be something like:
* Mobile works on wifi, not on cellular
* Desktop is fine, mobile is not
* Doesn't work on VPN, works when disabled

* One user works, other user does not

Thanks folks. I know this is frustrating, and we are working to find the best solution here.

@XfinityAlex I am having the same issue. My Comcast emails stopped syncing today. This is happening on my Window 11 computer using Outlook. When I try to repair the connection on Outlook, it says "We couldn't connect to the incoming (IMAP) server.” I had these same issue at the end of November 2025 and it took a week for Xfinity to correct the issue. How can I DM you my information?

@XfinityAlex with many many people in here all having the same issues, myself included, why do you keep sending them on a goose chase having them check their email client. If all of us started having this problem all of a sudden across multiple different email clients, clearly the issue is on your end

@XfinityAlex I was having the same problem on my android phone using Outlook. I eventually removed my comcast.net account and tried to re-add it back in. but get a log on failure. I also tried uninstalling the outlook app and reinstalled it and have the same problem still. (I originally tried other things like resetting the comcast.net account, clearing cache, etc.) The account is working fine on my windows machines.

Can you help?

Thanks

I have the same email issue again with "imap.comcast.net server timeout" today 12/18 on my Win10 desktop PC running Thunderbird. I am able to log in to Xfinity via my chrome browser to view my emails.
I hope it doesn't take 4 days to resolve like last time! LOL!

I have the same question as bucnutt above as I don't know how to send securely to you via "DM", as I am not on "social Media". Thanks...
