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.
