Can not connect to Incoming imap server to receive emails in Outlook

I have chatted twice with agents online and all I am told is that there is a problem and they are working on it. First it was give it 24 hours. I did...Outlook did connect once and I got a couple of emails...this was yesterday. This morning we once again return to not being able to download new emails into Outlook. Now I am told give it 4 more hours or call in for support. Calling requires sitting on HOLD for almost an hour. There is ZERO communication from Xfinity as to what the problem is or when it might be fixed. This all happened after Xfinity REQUIRED me to change my password. What is going on and why is there NOTHING online about what is going on?

I am experiencing the same basic issue. Thunderbird email cannot connect to imap servers. I receive a 1014 error. I started working with Thunderbird professionally about 1995. I have searched the web for solutions and finally attempted to configure the MS Outlook app. Same basic results. This all started shortly after a password change was made. The account worked fine for aprox. 2 weeks and the journey began...
The 1st indication of an issue was a pop-up stating my ip address was blacklisted (reasons unknown) the next day email was back to normal. About a week later I received the 'Blacklist' warning. I only send 10-15 emails weekly. My incoming is about 50-100 per day (mostly advertisers/SPAM). I am out of ideas to try. The generic mail client on my iPhone does not connect either...
Thanks for any assistance.

Thank you for your feedback and for commenting here on the Xfinity Forums. If you use Outlook to access your Xfinity Connect email account, you’ll want to make sure your settings are configured correctly. This article will show you how. And, you can learn how to switch your Xfinity Email account setup from POP to IMAP on Microsoft Outlook with details instructions here. Please let me know if this info helps, user_0djjip.

Over the past few weeks, I've repeatedly had outages for receiving emails.  At almost all times, I've been able to send.

At first, it was just my Outlook 2019 Home on Windows 11. I would repeatedly be asked to enter my password, and then received an error message that I had a temporarily blacklisted IP address. 

During the past couple of weeks, I've also had days where I could not access email via (non-Xfinity home) wifi on my iPad, as well.  Some days I can.  Today, I could receive emails earlier in the day, but not in the late afternoon or evening.

I've had repeated calls with advanced security support, and was bumped up to level 3, whatever that means. I was told that Xfinity is having known problems with connecting to email clients, and that the engineers were working on it. 

This evening, I got a call back from a seemingly knowledgeable support tech. He claimed that there were two causes for the recurring problems:  (1) a supposed blacklisting from my ISP, not Comcast, and (2) their own problems with connections. He suggested contacting my ISP, Microsoft, and Apple support. When I pushed him, he told me that Comcast no longer gives out email addresses to new customers, and implied that it might not support email clients -- especially for non-Xfinity internet households -- indefinitely. He urged me to just use their website to access email, and didn't discourage me from going to another email address and giving up on Comcast.

I've been using POP mail. He said it didn't matter whether it was POP or IMAP.

Just for fun, I then contacted my ISP. The support tech told me that they do not blacklist anything. Not surprisingly, the information from the Comcast tech about the source of the blacklisting message was wrong. 

The tech's (implicit) advice to give up on my Comcast email addresses may have been pretty good -- despite my having had them for decades. Of course, if I do that, I'll also cut the cord for my remaining cable and voice service.

NOTE - 24 HOURS LATER, IT'S BACK ON AGAIN, ON THE IPHONE AND WINDOWS 11/OUTLOOK 2019.

Well, after 10 days of working fine, email is off on all my devices over home wifi today -- except it was on for a minute a couple of times today, then off again.  Very frustrating.

[And back on again the next day. ?????]

bammo - We'd appricate the chance to help get this issue resolved. Is there an error message or code displayed when you're unable to access?

Go to security settings in webmail and enable "Third Party Access Security" to restore Outlook syncing. Not sure why their support cannot relay this very simple information \_(ツ)_/¯

@user_u370lr​ Hey there.  Yeah, that is an important setting, but like a lot of people, that isn't the magic bullet.  I've been working this since December 11, 2023 and I've tried every single recommendation.  I think it has to do with ISP IP addressing where the ISP masks the other IP addresses and it is confusing Comcast's IMAP server, but because we can't seem to nail this down, this is just a theory.  Moving to cell service to send email works, but go back to the ISP, can't send email routinely.  I hope this check box works for you.

I have been having this issue intermittently for months now.  I'm a "legacy" comcast/xfinity customer after paying for 30+ years moved to an area with no comcast service and retained my old email accounts.  Here was my fix that I discovered today Windows 10 running Office 365:  

1.  From Outlook file menu select Account Settings.

2. From dropdown menu select Account Settings.

3.  Highlight account that is not connecting to server.

4.  Click "Repair" from banner above.

5.  Click "Advanced Options." 

6.  Check box for "Let me repair my account manually."

7.  Click show password button to reveal password.

8.  Make sure password is correct--both my comcast accounts had extra characters before the password--removing the artifacts resolved the issue.  I don't know where these came from, but I certainly did not put them in.

@user_yrfv0x​ Thanks for adding this to the possible fixes.

I tried this method and found something unusual.  I changed my password through my Chrome browser at xfinity.com.  I then went to my Outlook 2021 client and tried to save the new password using the repair option.  It wouldn't take it.  I put the old password in and it took it.  I closed Outlook down and restarted it.  Still wouldn't take the new password.

I then saw something in the repair option that mentioned a password list in Windows.  I went to Run and entered inetcpl.cpl, went to Content Tab, AutoComplete, Settings, Manage Passwords.  Windows creates passwords and saves them locally.

I found several under Windows Credentials that showed my password had changed today which one pointed to a POP device.  I deleted all the credentials listed that changed today.  

I then went back into Outlook and after restarting Outlook I was able to enter my new password.  

I was on my hotspot 4g connection which allows me use Outlook without issue. 

Once I connected to my wifi, I was able to send and receive OK.  I say this with a bit of skepticism as I can send emails at certain times of the day, typically between say 7PM to 10PM (sliding window) so if I find that I fixed it, I won't come back and let you know.  If it didn't work, I'll be back.

I've been having this problem since December 11, 2023.

Good luck!

@getnoldfast​ So, after waiting until this morning, I'm back to email not sending. I can receive and have always been able to receive email, but sending is hit or miss.  So annoying.

@getnoldfast​ Not sure why as I wasn't messing sith anything, but, yesterday I was able to send and receive alllll day without any issues.  Then of course, today, thinking it was fixed, I can't send email again.

So, if COMCAST was doing anything on September 20, 2024, put the settings back to those on that day as it was working.

I am very very frustrated.  I am experiencing the exact same issues as the posts here.  I changed my email password and now cannot get Outlook back up and running. I need this fixed and am tired of spending hours on the phone or on a chat session going through the same issues day after day.

My troubleshooting would indicate that it may be the IMAP Incoming and Outgoing Servers pre-populated.   This is NOT a Microsoft issue.  Xfinity needs to realize they have created a BIG problem and provide a proper FIX it.  The 3rd Party Email Setting enablement has a bug or other issue causing this problem.  

I hope to hear from someone with answers today.

For all here, I figured out that this was a Norton Anti-Virus/VPN issue.  I had to temporarily disable Application and Connection Blocking which are Firewall settings.  I was then able to re-add Comcast as an Outlook account - bingo!  I am now fixing Norton to re-enable these settings and am off to the races. I figured this out by querying online posts and Microsoft suggested trying this fix.

@Glober​ Unfortunately, this does not work for me.  Still get send/receive errors if the VPN is on.

user_p8dsjn have you tried disabling the VPN as mentioned in the solution? Or when the VPN is off?

I don’t know if this helps but I was trying to get my email to connect to my mail app on my iPhone. I had to log in to the Xfinity website, go to my email inbox, select settings, then click on security. There’s a check box for third party access that was unchecked. When I check marked it, it started to load my emails. I wonder if that’s what you need for outlook?

After several months of working fine, this morning my Windows and Apple devices could, once again, not connect to the incoming email servers using Outlook or Apple Mail. I switched earlier this year to my building's residential wifi, and that caused the original problem.  (My service was on and off for a couple of months.)

The residential wifi is, again, "temporarily blocked."  My guess is a software update was made since yesterday by xfinity.  That must have deleted the solution and caused the problem, once again.

I called Advanced Security at xfinity, and they promise a call back within 2 days.  (That hasn't always happened in the past.)  Very frustrating.

@bammo​ I'm receiving emails fine this morning on both Outlook2019 on Windows and Apple Mail.  I hope xfinity fixed their system overnight, that it was just a one day blip, and that they will not relapse again.
