Thanks for trying, but unfortunately none of that is helpful. You have directed me to the very link which throws up the Windows email app registration process which I am unable to successfully complete, as I described above. That is the very barrier that prompted me to post my question here.

   Since you suggested it, I did visit the privacy settings page. I saw nothing there to help with phishing emails, but while I was there, my attempt to set my marketing preferences led to a dead end.  Please see screenshot. Did that happen because I'm in the UK at the moment, or was it yet another example of poorly designed systems at Intuit?

   If Intuit is serious about the abuse of their name and the abuse of their customers, they should provide an easy and direct way to report phishing emails, as many other companies do. I've now spent hours on what should have been a straightforward process. It shouldn't be this hard.

   That said, do you have any other suggestions on how to report a phishing email? Thanks again for trying to help.
