The Comcast 'technician' imagines you are using an Outlook.com e-mail address as your primary e-mail account. That's because Microsoft in their wisdom ◔◔ decided to have Outlook (an e-mail client) and Outlook.com (an email account) share the same Outlook name but mean different things.



The problem seems to be that the Comcast address is being treated as spam by the server, though knowing nothing about Comcast that is only an educated guess.

You could also investigate your own AV software. Some third party AV software can be overzealous. Personally, and with Windows 10, I prefer to use Windows own Defender option, however this is not as fully implemented in Windows 7.

As an aside, I would recommend the Office 2010 32 bit version rather than the 64 bit version as it creates fewer problems, but it may be a bit late in the day to make that change.

You may be correct about the Comcast 'technician's' assumption about Outlook and Outlook.com, but I did give them my e-mail address (xxx@comcast.net) during the tech assistance sessions. I think you are right about the Comcast address is being treated as spam by the Comcast server (however little sense that makes).

However, your analysis doesn't explain the entirety of my problem. Why does the issue persist when I send e-mail out on my laptop, an entirely different computer, using a different installation of Outlook, and even a different version (2019), while using a profile with my desktop e-mail address? Further, and I didn't mention this in my original post, but I also have the problem when sending e-mail from my iPad or iPhone, which I have set up to access the same comcast.net email account I use on my desktop? (In case you are wondering, I use a POP3 configuration, not IMAP.) It also makes no difference whether I am on my home network or using an xfinity hotspot. I can also change profiles on my desktop computer to a different comcast.net address and NOT have the problem.

In short: 1. No matter what computer or e-mail client I use, my xxx@comcast.net (desktop address) fails. 2. No matter what computer or e-mail client I use, ANY OTHER e-mail address works.

I have to conclude this is Comcast's fault, but they flatly refuse to do anything about it.


I also misspoke in my original post: I said I did NOT have the issue when using my desktop e-mail address in a profile on my laptop. I DO have the problem in that circumstance.
