SMTP settings in Outlook

@XfinityAnna​ I followed the steps and it still does not work.  Server times out.  It has been since Comcast changed security settings 4/13/22.  that I have been unable to use comcast emails in Outlook 365.  I have gone into my account and allowed 3rd party etc.  To no avail.  The only thing I have not done is delete accounts in Outlook 365 and add them again.

Here is the error log.  

17:56:15 Synchronizer Version 16.0.15225.20070
17:56:15 Synchronizing Mailbox ' [Edited: "Personal Information"]'
17:56:15 Synchronizing local changes in folder 'Inbox'
17:57:50 Error synchronizing folder
17:57:50    [800CCC0E-0-0-430]
17:57:50 Done

Obviously I changed email user name in log for forum.

Any help would be greatly appreciated.

This has been happening to me as well.  I have tried multiple (Outlook and Thunderbird)  It works fine on the portal but NOT with a 3rd party (And yes I already checked the 3rd party box in the settings)  I am just about ready to leave Comcast for GOOD.  Why for more than ten years does this work and then all of sudden stop.  Makes no sense.  

Please post your settings for Outlook and Thunderbird.  You can verify them here:

@user_10dc44​ I feel your pain.  I'm also about to give up on Comcast for all services.  I am sad that this is not resolved.  I manage my fathers email for him as he has low vision and it was convenient to have it all come to one place.  I could stay on top of it for him.  Now I have to go directly to Comcast to view.  A major pain and time consuming.

While my experience with Comcast Tech Support has genereally been favorable (unfortunately those support wash off their hands by saying "Comcast cannot provide tech support for Outlook related issues. You will have to talk to Microsoft"), I find that the "Official Xfinity Employee"s who answer these questions on the forum are not that helpful when they give links to various post. As far as I can see from the User forum, the Outlook 2019 issue has been around at least for 2 years (though I was exposed to it only in the last 2+ weeks) and no resolution has been forthcoming from Comcast. In my experience, this is unusual from Comcast. I do not know the precise mechanism, but this issue has to be elevated to higher levels at Comcast. This is simply unexplainable behavior on their part.

Thank you & Regards,
