Sorry to hear that Jason. I can only offer one suggestion that seems to have reduced the number of e-mails I receive. (Refer to my post from November 18.) I'm receiving these e-mails on my bigpond.com address and have had to use their web-based e-mail client to block the sending domains. (Although you can use Outlook to block these, the blocking specification doesn't get saved on the bigpond.com server so the e-mail doesn't get blocked at the server.) The bigpond.com server only allows the blocking of senders from a particular domain using the syntax *@<domain_name>. Sadly, you can't specify something like *@*.onmicrosoft.com. So, as tedious as it sounds, I can only suggest you try a similar thing on your e-mail provider's server. That is, try, for example, *@xyz.onmicrosoft.com, for the 'xyz' subdomain.
