Organizing and accessing contact information in Outlook.com
I followed those steps and I could not view the header (MS 365-Outlook), but the BODY of the email had a reference to a website with www.hiboss.edu." as part of the displayed HTML code in it. I created a rule that searched for that specific body text and deletes it. Worked great (for now). However, there may be other such spam with different content, so I am pursuing writing a macro that searches for the empty sender or the
removed for privacy" text and delete it that way. I already have a macro that does something similar for junk senders containing "/"s and other special symbols as part of the name. That will save me some work.
Maybe some good hacker with a good block on their incoming mail (for protection) could spam that sender with a few million msgs a day as a DOS and teach him a lesson.
