All comcast.net emails stopped working 2 weeks ago, still no luck getting any help from Comcast

I am currently having trouble sending email on comcast using either Outlook, or our iPhone's and iPads.  This started happening about 2 weeks ago.  There are no issues with any of the settings.  I've been on the phone with comcast support, and after about 2 hours, they say they will call back, but never do.  I can still recieve email fine.  Originally, I would get the message that my IP address was black listed when trying to recieve email.  I then contacted my ISP and had the IP address changed.  Once this was done, I can recieve email fine, but still cannot send email.  the message I get when sending is:


Task ' [Edited: "Personal Information"] - Sending' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'

Keep in mind that I have spent probably close to 10 hours on the phone with comcast at this point.  When I change my cell phone to the cellular network, instead of the home network, I can send email again via comcast.  When I hotspot my phone to my laptop, I can send email again as well.  There are no firewalls on the network blocking anything from working.

My email addresses are legacy, as we moved to a location that comcast does not service.  I've heard from posts that I have read, that this issues is mainly happening to people who no longer have Comcast accounts.  It sounds like Comcast would like to see all of us just give up and stop using their email service.  If this is the case, then tell us.  Don't just make it impossible to get things to work.

It wouldn't have been so bad, but the email stopped working the morning I went in for major back surgery.  Since I've been home attempting to recover, I've needed to spend enormous amounts of time dealing with this issue.  It can't be that hard to resolve, as I've seen other people post that Comcast was able to fix the issue.

This issue is a problem that Comcast have known about for years. I'm a recently retired IT technician and I owned my own repair shop. Two years ago, I had a client (attorney) who had experienced this exact same issue which stumped me for a while but I sent out a tech I've known for years who was a networking genius, he had written code for Netgear and setup our town's fire station, police station and school networks. He ran some tests of where the breakdown was occurring and after nearly two days of trying different computers, routers, router settings, versions of Outlook and several protracted calls with ISP and Comcast, the only solution was for the ISP to supply a fixed IP address and then configure the computer/router to it. Comcast eventually paid for this...after some wrangling because it had to do with the limited pool of IP addresses available to their servers.

Seems to me like they're cutting back on their clients, maybe weeding out some that no longer use their services? Just guessing....but they do have history with this issue.

I can easily configure my system at the house with a fixed IP address. I would hate to then have them black list that one.  I have a 1 gig fiber from JC fiber, and yes they do have address limits.  It’s only a small amount to switch to the fixed IP.

i do believe you are correct, Comcast just wants to get rid of me.  If that’s the case just say so and give me a month or so to get things changed.  It’s no wonder Comcast has such a poor reputation.

@user_ss3xpn​  I plan to work with my ISP this morning on configuring a fixed IP address to hopefully eliminate the issue.  I created another response this morning on the issue.  I'll let you know what happens.

Well, I sent a direct message in response to this message, and it lead no where.  Luckily, so far since paying to obtain a static IP address my email has been working again.  This has happened before, so I'll post back to see if it stays working for a while.  If this is what I needed to do, why couldn't that have be suggested 2 weeks ago?  Also, whey black list an IP that actually has nothing wrong with it?  This has been one of the most frustrating things I have ever had to go through.

@user_ss3xpn​ I just wanted to post the results of "Paying" for a static IP address.  So far, once the new static IP address was created for my home network, my Comcast email has been working fine.  It's been working almost 48 hours now, so I am very hopeful.  Yes, it appears that Comcast has an issue that is known by most of the ISP network engineers.  The only people that don't seem to know anything about it Comcast.

I'm hoping this issue will now be resolved for an extended period of time.  But we will begin moving all business, medical, and personal email to a non-Comcast account, as Comcast seems to be so un-reliable.  

To date, not a single open ticket that Comcast created to deal with my problem has ever had ANYONE call me back.

Thanks gain for your assistance

@user_76ae15 Just to clarify, are you able to log into the Xfinity website to check your email with no issues? Is it only the third party email apps that you are receiving an error with?

29 Messages

Yes, the on-line portal has worked during the entire ordeal so far.  I did update the passwords to all of the email accounts as well.  Comcast has gotten the email to work for a short while, like a few hours.  But then it starts having issues again.

@user_76ae15 Have you tried going to the list of apps on your phone, click on the third party email app you are using and then select clear all data or clear all app data? Depending on the app the wording may be different. We've found that this can help resolve this type of issue with third party email apps.

Please remember that the issue occurs with the Iphone, Ipad, and Outlook on the PC's  I can't see how data in one app would shut down another.  Also, I've jumped through countless hoops on this, both deleting email accounts and attempting to re-install them.  If I delete an account on the iPhone, and have the phone connected to my network, it will not install, and eventually gives an error with SSL.  Can't remember the exact error now.  But if I go back to the cellular network, it did install properly, but sending email while connected to the network still fails.  Basically, the outgoing server is rejecting log in if I am on my home network.  There are NO APP specific settings that cause this.

@user_76ae15 The PC may require different troubleshooting steps, which we can definitely look into. For the apps on the iPad and iPhone please try the steps I provided above to clear the data from those third party mail apps and let me know if you still experience this issue with the iPad and iPhone.

I've looked for ways to clear app data on my iphone, and even done a search.  the only things I can come up with, are to delete the "mail" app, which then requires a reload the app and accounts.  I've done this once already ( yesterday ), and don't have plans to do it again.  How does doing this multiple times help?

@user_76ae15 For Apple products you should be able to go to your settings, select "General", then select iPhone Storage, then select the app that you would like to clear the data from, then you would select, "Offload App". This is a different step than completely deleting and re-installing the app.

OK. I just did "Off load app" and then re-installed the app.  the email I just sent is still sitting in the outbox.  after waiting, is eventually says the connection to the outgoing server failed.  Additional outgoing servers can be configured for mail.

Here's the real reason why you email clients won't work

https://www.wsj.com/tech/cybersecurity/comcast-says-data-of-36-million-accounts-was-compromised-in-breach-1af59984?st=is2yajr4c6k2dwi&reflink=desktopwebshare_permalink

Kept that very quiet didn't they!

Comcast's "solution" so far is to refuse people access to their Comcast account until they reset their password. This only happens if they go directly to Xfinity.com to retrieve their email (or for some other purpose) so it's not going to help the majority of people, who pick up their email in Outlook or Mac Mail., or on their phone's native mail app.

Hello 3xpn,

Actually I did change all the passwords about a day into the issue.  I needed help from Comcast to fully access the accounts since a few of them did not have a recovery cell phone number.  It did not fix the problem.  The final solution was to have my ISP give me a static IP address.  That did fix the issue.  The real sad issue is that there were at least 3 open tickets opened trying to deal with this, but Comcast never called me back on any of them.  Luckily my email has been working fine the last week or so.

@user_76ae15 Could you send me a DM with your current IP and username that you're trying to use (when the issue is happening)?  I can see the UID attached to this forums account, but I'd like to make sure that is the one I should be inspecting.

Usually this is related to a forgotten device or application still attempting to use an older set of credentials.

I definitely feel your pain after days without email & dozens of hrs scouring forums, trying to talk to a tech rep, & running ragged circles around online solutions that led to nowhere in trying to reset my husband’s email password.  We also are not Comcast customers since moving to a non-Comcast area;  we have had xfinity email accounts for over 20 years.   Early this morning, I found info regarding Comcast Security Assurance.  You can actually talk to a live person from 8am-12am EST M-F; not sure about weekends. I called exactly at 8am this morning (Tues). & was put on hold with repeated messages stating wait was over 20 mins.  After about 10 mins, Keiya answered & was exceptionally helpful.  I chose prompt #3 from Comcast Security Assurance (1-888-565-4328); prompt #3 is for non-Comcast account holders.  She walked me through a process to issue a numerical code to reset password. This fixed the problem & all of my husband’s emails returned. We could access them through connect.xfinity.com &/or my.xfinity.com.  Once account was restored, we then synced the mail accounts to his laptop & IPhone mail apps so that he would not have to access through the websites.  The cause of the problem was an old password.  We have to update passwords more often in the future to avoid block-out.  I hope this info is helpful to all frustrated customers.

I have two of my three comcast.net email addresses that have suddenly become nonresponsive.   Will not send or receive.   Nothing has changed recently that could cause this.

I desperately need these back up and running.  First, how do I get these emails working again and second, how do I maintain the accounts?   last time I had to do anything with these email accounts there was a Comcast log in for me to manage the emails.   That doesn't seem to exist anymore or i can't find it.

Any help appreciated.

Thanks.

Are these secondary accounts?  Are you still a Comcast customer?  If not when was the last time you logged in to the website on those accounts?  You can try calling Customer Security Assurance to see if they are able to restore those accounts.

Same exact problem.  Comcast does not have a clue.  Only solution I found was to switch to another provider and have my Xfinity email auto forwarded to the new provider.   According to lengthy discussions with Xfinity, there is no problem.  I too cannot get Xfinity service where I currently live and am using a legacy account which they made inactive.

I'm having the same issue! Also getting an error when trying to send emails that has a red exclamation mark with "Error- an error occurred inside the server which prevented it from fulfilling the request." Has anyone had that?

For months my Comcast email has been so slow. Sometimes 3-5 minutes to send an email or open the browser. The the last few days I have been getting these errors over and over again. I called Comcast today and was on the phone for an hour. Seems to be working now, but we'll see if it works long term.

I'd love any advice from anyone who had these errors and got them fixed  :-)

I lost one email in January and now the other one in May. It is so frustrating. I did all of my business through that email. 

Comcast has no live person to talk to. I finally got through to someone and they said they couldn't help but they would have someone call me. Surprise surprise no one ever called back. 

Why doesn't comcast have a customer service line anymore?

Hello user_nhbnsc, emails are super important, so I can only imagine what this has been like for you. By chance, were the emails you lost access to the primary email account attached to your account? Also, have you recently logged into the Xfinity website to access your emails with any of your email accounts?

I have the same issue. It has been happening for the past several years on and off. I have decided to change my email and dump Comcast/Xfinity completely.  I think a lawyer might want to take on this issue. It would make an interesting Class Action and investigated thoroughly.  It is one thing to decide to mess up people's emails without letting them know you are discontinuing email service if you are not a paid Xfinity internet/cable customer and another to start creating issues so they will leave. This company is a mess and is highly unprofessional. Just my thoughts.

I had to work at finding a human being to speak with. They did a reset and it worked for a couple of hours and then returned to the error. Very frustrating.
