3rd Party email not working again.

Hello, @user_5183a1, thank you for detailing all those past steps you've taken and the ones from the last time this popped up. I'm always in my emails, so I get how important this is. You mentioned a few things regarding your Comcast email, but I wanted to make sure we're on the same page. You're able to log into the Xfinity site and view your emails? Also, have you already reached out to eM Client for any troubleshooting on their end? 

Yes, web-based email works fine.  eMClient said all my settings were correct.  I have tried other 3rd party email programs like thunderbird and the same happens, my credentials cannot be authenticated.  It's an issue with Comcast and 3rd party emails.  Yes, I have checked to allow 3rd party email in my comcast settings.

Thanks for sharing that information, @user_5183a1. Is this happening on all of your devices? Have you tried any other device to see if the same issue occurs?  

I only use 3rd party email on my desktop, nothing else.

Do you have any other devices you can try? (PC, laptop, tablet) I just want to confirm the issue is happening regardless of the device you use. 

Hello @bob0006, thanks for reaching out to us on the forums. I am sorry to hear this issue is happening I know how frustrating it can be to not have your emails go through or populate as intended.

Thanks for letting us know all you have done on your end to attempt to resolve the issue and I appreciate you taking the time to do that.

Does this issue with Outlook happen on all devices or does it only happen on one device?

Hello @kleemckinney what version of Outlook are you using, and has this been successfully set up previously? Are you able to confirm all settings are correct in Outlook as this article shows? 

@user_e27690​  I spent a couple hours on xfinity IM trying to figure out this problem.  After all the usual troubleshooting they said everything was correct on their end and to contact my 3rd party.  It is not the 3rd party email, I have also tried 2 others and get the same messages about authenticating and credentials, this is not a coincidence.  My latest attempt at a different 3rd party says my IP address is temporarily blocked.  Now I'll try to figure that one out.  It seems comcast servers don't like 3rd party emails.

@kleemckinney​ 

@kleemckinney​ They told me it's not a known issue.  Said they would contact me if something comes up, basically.  That doesn't help me any nor will I hold my breath.

Hey there @kleemckinney good to hear from you! We had responded to you earlier post to ensure that all settings for Outlook were correct. Have you had a chance to review this?

@bob0006​ I can't send or receive mail at all from 3rd party emails.  Any third party email I even try and set up doesn't get passed the "Authentication failed, credentials reject" stage.

@user_681896​  I am now waiting for a call from Comcast's "Level 3" customer support, whatever that is, and I'm not holding my breath over that call either.  I have found no solutions nor an inkling from Comcast what it is.  They try and blame the 3rd party, but I've tried 4 (FOUR) different 3rd party email programs and the results are all the same.  My business is seriously hampered by this too.

@XfinityBrandon​ What exactly is "Level III" customer support?  My issue has been sent to them and was told I'd get a call within 24-48 hours.  5 days later and no call.  I call them today and now I'm told it takes 5-11 days for them to call.

@jagm5122  - Again is correct you do not have third-party clients enabled in your settings. The directions are posted on the article linked by Again.
