Our personal email accounts, which we have used for years, are through a domain name from Melbourne IT.  (dorlac.net)  We sign in to use this email account through Hotmail, now Outlook, and have done so for about ten years.  Starting on 10/31, we can send emails without difficulty, but receive no emails.  This is not a problem with junk mailboxes or filters, and it appears I am not alone in this problem.  If anyone can help me figure out how to fix this it would be incredibly helpful.  I am not particularly IT savvy, but I can follow instructions.
