I have been a Comcast email user since 2013 and up until the last two weeks I have been pleased with the service. I moved to a non- Comcast serviced location in 2018 and so have been a legacy email-only user for the past 6 years.
My problem is similar to that described above, i.e. my Outlook 2021 is unable to consistently and reliable connect to the inbound server "imap.comcast.net" using my Xfinity credentials. I was able to contact tech support today and made it very clear that I needed an app password to so that I could appropriately connect to my Comcast account via the 3rd party Outlook 2021 app on my PC. My Xfinity account (which may lack functionality since I am not a paying customer) does not provide me with an opportunity to generate an app password that can be used to establish a comcast email connection with Outlook 2021.
I could "trick" the incoming server for short stints by turning on and off my Norton VPN. Apparently I was temporarily circumventing the "temporary blacklist" issue which appears to arise when Outlook pings the server too frequently.
BTW, my contact with Comcast today began with a chatbot>>human chat center with 3 individuals with limited expertise>>> to escalation and two call backs within a few minutes. Unfortunately, the conversations were quite scripted and were ultimately nonproductive.
In summary, I was provided with the 800 number to Microsoft Hotline chatbot which turfed me back to this website and this thread which is really quite helpful other than my Xfinity account did not have app password generation functionality (tried 3 browsers just to be certain).
Any assistance would be greatly appreciated. Thanks in advance!
