Can't connect from Mac Mail to Comcast email

I tried that. In fact when I did, I couldn't recreate the account. When I tried, it said that the account still existed, although it no longer appeared in Internet Accounts. After using someone from JustAnswer for hours, he was able to recreate the account, but when I try to connect to Comcast, I get the message that the password and account cannot be verified. I'm suspecting it's a problem with Mail, but when the JustAnswers agent ran out of ideas, he suggested I contact Xfinity. Good luck with that!

Thank you for reaching out to us on our community forums @user_syqu58! I see our awesome expert @Latoque also provided some good tips that can generally resolve this problem.

I appreciate you for confirming your tried those steps. Just to confirm did you use this article from our site and this one from Apple’s site to set up the email address with the mail app on your Mac?

I am having the same issue. After reading this post, I went to the two articles you suggested and saw:

• Sign in to Xfinity Email using your Xfinity ID and password.
• In the top-right corner, click the Gear icon, then select Settings.
• Click Security.
• Uncheck the box under Third Party Access Security to prevent third-party programs access to your Xfinity Email, or check the box to allow access.

Actually, the box says to check it IF YOU WANT THIRD PARTY ACCESS. The box is not checked so I checked it (because I want third party access). here is a screenshot.

Something is not right. Is this an issue with the new updates in macOS?

Did all that and still doesnt work

Hi, user_fg5o8i! Thanks for taking the time to visit XFINITY for help for getting the Comcast email to work with the Mac Mail. We can help. To provide our customers with additional security, we added a new checkbox to the Xfinity Email website. This may affect your ability to manage your Xfinity Email (Comcast.net) through a third-party program such as Mac Mail. The security setting is checked by default. You can easily change this setting at any time by checking the box and turning on access. Here's how. Please let us know if this helps.

1. Sign in to Xfinity Email using your Xfinity ID and password.
2. In the top-right corner, click the Gear icon, then select Settings.
3. Click Security.
4. Uncheck the box under Third Party Access Security to prevent third-party programs access to your Xfinity Email, or check the box to allow access.

Does not fix the problem. I can no longer get my email on my Mac or phone.

Having same problem! Been working at it for weeks. There is no chat icon near the bell icon.

Seems like neither Apple or Comcast want to take responsibility for this. I don't see it ever being fixed.

@lchaney Thank you for taking the time to reach out to us here on our Xfinity Forums. Just to clarify, I understand that the third party app is not working as intended for you. Are you able to still send and receive emails via the Xfinity webpage?

You are lucky you can still get it on you phone. I can't get it on MacBook, iPhone or iPad. 

IT IS SO HARD TO GET THE BOT to give you CUSTOMER SECURITY ASSURANCE!!

I was able to resolve this issue. On my Mac Studio I do not use my router to provide my DNS addresses, I use cloudflare DNS. When I switched back to use the Comcast DNS servers I could add my account again.

Great! Thank you for letting us know and providing the resolution here as well. If there is anything you need in the future, please let us know.

@XfinityBenjaminM​ I rarely use my comcast.net email address and this is one of the reasons why. I should be able to use any DNS servers I want to instead of being forced to use Xfinity's. I'm just leaving it disabled as I can use my preferred DNS and check my comcast.net email on my iPhone instead.

Thank you for the additional context and we appreciate your feedback.

I've tried the 3rd party app settings.  Can someone please explain the DNS servers?

Hello, @user_u5spgh. I appreciate you making us aware you're having issues setting up your email using a third party email service. Please visit this link to match your email settings to what is listed on here https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email.

I found the same thing with mine. It now works with the CloudFlare DNS.

Hello user_kp3cqt have you had a chance to check out these articles Xfinity Set up Email and from Apple specifically? And have you ensured that Third Party Email Access is enabled in settings via Xfinity Connect? 

Also!  I found another potential problem. This is if it isn't working for you at all.

If you sign into the web interface, there is a "Security" option to enable third party Apps. If this isn't turned on, NOTHING WILL WORK.

I'm not sure when they added this, but for one customer, logging into the web interface and then enabling third party apps (under the gear or settings in web mail) then waiting 15 minutes fixed both the phone and the Mac,

They added it several years ago.

Same issue. This is maddening.

Greetings, @user_ec5pv0! Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues with your email account, but you have definitely come to the right place for assistance.

I was not able to find any information about connecting via Cloud DNS, unfortunately. It may be past our demarcation point, or it may be listed under a different process name in our system. Here are the step-by-step instructions we have listed for MacMail:

To connect to MacMail with your Xfinity email address, follow these steps:
1. Open MacMail on your device.
2. Go to Preferences and select Accounts.
3. Click on the "+" sign to add a new account.
4. Enter your name, Xfinity email address, and password.
5. Choose IMAP as the account type.
6. Set the Incoming Mail Server to **imap.comcast.net** with port **993** and SSL on.
7. Set the Outgoing Mail Server to **smtp.comcast.net** with port **587** and TLS encryption.
8. Click Add Account to finish the setup.

For more details, refer to the official Xfinity support page for MacMail setup at https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email

Hello, @mikeg0305. I'm sorry to hear you're also experiencing the same email issue with your Mac account. Have you checked the IMAP and SMTP fields to make sure they are correct?

I am also having this issue!  I also enabled 3rd party apps,  (I have had this email for 20 years and why it decided to change now who knows), and changed passwords (this has happened before and that worked). I also deleted the accounts and tried to add them back.  I know I have the right password as I can log into xfinity and I just copy it over.   I AM SO FRUSTRATED.  You cannot talk to someone.  How am I supposed to get stuff done?????  I have been a customer for 20 years.  I feel like dropping you with so little support.

Hello hroruser we thank you so much for taking the time to reach us via our Community Forums and adding your experience on this thread. We'd like to connect 1-1, so we can look at the email setting on our end. 

Please send a direct message by clicking the chat icon in the upper right corner of the page, clicking on the pen and paper icon, and then entering “Xfinity Support” in the “To” section. Please include your name and address, and I'll be happy to help.

Hey there user_5gf6g6, thanks for reaching out to our Forum. I'd love a chance to work with you more to find a resolution. Let's get on the same page, can you please provide me with some background details regarding your concerns?

I am done with trying to set up Comcast.net on my Mac.  However, I have a lot of accounts that links to this address.  Does anybody know how to set up autoforwarding of my incoming comcast.net email to my gmail account?

Same issue here with my iPhone.  Can receive but not send.   The port number is set correctly and third party is enabled.
