Hello, I have been using Comcast email for a long time and have it set up on the Mail.app on my Macs at home, office, etc. On Friday, I noticed that on a home Mac I couldn't get connect. When I went into my Internet Accounts in System Preferences and tried to enter name (user name) and pw, I get a message "Unable to verify account name or password."
Curiously, this occurred simultaneously on three different Macs all running version 10.13.6 macOS (current High Sierra) in three different locations. However, my MacBookPro, which was off on Friday, works fine for Comcast email. All Macs work fine using web browser to log on to Comcast email. iPhone email is ok too. Any advice appreciated. I don't know if this is some kind of Comcast problem or maybe iCloud (which seems to do something with other email accounts)? thanks
Well, I think this was a problem with iCloud keychain since kept reverting back to incorrect settings. I checked using web browser and all my imap email was still online, so I deleted the bad account in Internet Settings on my Mac, which didn't affect imap email using web browser. I then added my comcast account with correct settings and am now back to norml. All imap emails are now back on Apple Mail. Just a FYI if anyone else has this problem.
Ever since my wife got a new iMac, she has had problems with smtp.comcast.net.
And now I can't even add Comcast after deleting it. It does not recognize my password after spinning for a couple of minutes. I called Comcast and they said it wasn't their problem since I could use their webmail instead (UNBELIEVABLE!).
Try configuring the account manually. When you get to the menu asking for the user ID and password, deliberately type in some gibberish----anything but the real password. It will try to validate it, and after about 20 seconds or so you will get prompted to set it up manually. The settings you will need are found here--------------
I am on Apple Mail 10.3 with Sierra OS. Suggesting to type in gibberish in the pasword area and wait, then re-type known password does not work for me.
Since I reinstalled Sierra OS on my Mac, I worked with an Apple Sr. Tech to reconfig my email accounts and he could not resolve this issue. He told me to contact Comcast Tech Support. After no resolution with Comcast, they passed the buck back to Apple. Comcast servers not recognizing my password for outgoing mail. Also changes password before my eyes when I type in manually and wait a few seconds, per your instruction on this forum. My password is recognized from the Comcast website though.
I followed the online documentation. Comcast tech directed me to the Comcast CSA Dept. tomorrow morning. Bad solution. Sr. tech support should be available up until 9 pm.
Really Comcast. You should get together with Apple to troubleshoot this bug since Apple products are used by so many people.
I'm curious-----exactly what happens when you try to set up the account? Are you getting any error message? I'm using Mac Mail v12.4 in Mojave and I'm running 5 Comcast accounts in it at the moment with no issues.
I'm having the same problem. Outgoing mail server not working for comcast. Deleted account, now I can't add account. Tried the "gibberish" thing and that doesn't work. I just get the spinning icon until I cancel.
Has anyone resolved this issue? Comcast says it's Apple becuase I can access comcast mail in browser.
Hello, all -
Thank you for reaching out here. I would be happy to help with the email issues, we want you to be able to access your email from places that work for you. Sounds like I'll need to submit a ticket. Please send me a PM with your first/last name to get started.
I'm answering my own problem here-
After speaking with Apple, it was determined that I had Malware on my hard drive. They had me download and install the free version of Malwarebytes. It removed the malware and I was able to add my Comcast mail account.
Thank you for the update, HeidiBoston! Glad to hear it's working now.
jpkempler, did you run a malware check like HeidiBoston did? Have you checked out your email settings here: https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email
