Emails on iPhone are not working

I use an iPhone (16 Pro; iOS 18.5) and continually get error messages for Comcast. First I was continually prompted to enter my password (done), and would sporadically get emails after a few prompts/responses. But now I haven't received emails for weeks and get the message:  "Cannot get mail; The mail server "imap.comcast.net" is not responding. Verify that you have entered the correct account info in Mail settings. Server code "AUTHENTICATIONFAILED", server message "Authentication failed". "

I've done all the actions suggested in other threads without resolution. Help and thank you!

Hello user_etx2qb thank you so much for taking the time to reach us here via our Xfinity Forums! What email service are you using on your iPhone to receive Xfinity emails?  Are you able to login via the Xfinity webiste, and see the missing messages?

@XfinityAlfonso​ I am using the default iOS/Apple "Mail" app. When I log into the laptop, I see the messages that are not coming through to my phone. As of today...everything seems synched up, but that has not been the case lately, and each episode lasts longer than the previous one.

I see, thank you for letting mew know! So the "sync" is now working as intended on the Apple devices. Is that accurate?

My spouse and I are experiencing the same issue. We have both deleted and re added the email to our phone. Is there a fix for this? We both have I phone 16s

I can’t wait for Xfinity mail to transition to yahoo mail. This has been a problem for a long time. I now just check my mail on the web.
