trouble with email sub accounts

I just had to reset my email password as well. That is a big ask for me because they never ask and so I am thinking they got a major breech. Might as well change your other passwords

@Ayy 

I have a problem.  Xfinity made us change our password on our main email account.  Now the sub accounts can't be accessed and we get an error message:  "ERROR-failed to load messages" and "ERROR-mail server imap.comcast.net denied connect attempt.  ALERT Temporarily blacklisted IP address  Try again later."

Please help, it has been going on for 2 days.  We really need access to our email!

I have tried and tried to use the xfinity assistant.  What a joke, she doesn't understand my questions and I end up in a loop of non responsive bubbles.  Very frustrated!!!

My Apple Mail on iPhone iPad and MacBook Pro have all been changed correctly. I can send and resend mail but a few minutes later I’m asked to login again. XFINITY maybe ya shouldn’t have asked every darn customer to change their passwords at the same time. This support forum is loaded with people who either can’t login after changing their password or people complaining. 

Well I can send Mail from Webmail, but when i try to send from my other addresses to Comcast mail--its rejected and says account doesn't exist 

I've deleted Account from Android Phone & Outlook 365, as it kept asking for the Password and yet the password was entered

Guess Password change went successful 

Well, I read somewhere that Xfinity did have a breach and that they notified customers Monday. Hmm, I never got a notice. Maybe because my email was not working correctly? None of the suggested solutions worked, but at some point this week , my sub accounts just miraculously showed up again. So I assume this was related to the breach. I wish they would have just told me it would be fixed instead of having me waste hours on suggested solutions that didn't work and having to explain my issues over and over again to different people. My email still does not work on either my iphone or ipad, hopefully that will just miraculously appear soon also. I got another text from a bot asking me if i would recommend Xfinity after my recent contact with them, and if not to let them know my problem. Like an idiot, I again described my problems and then was rewarded with a series of non-related choices: billing, speed, equipment, connection, etc. Yikes!!!
