    From Outlook, you can go to File > Manage Rules & Alerts > New Rule > Move messages from someone to a folder and under Step 2 you will need to specify from which address or domain you want to include and then still on Step 2 select the Junk folder and then finish the setup from there. You can also see the link below for reference as it has a couple of email addresses where you can also report this to Google as firebase it part of them.

    Hello, good day and thanks for your question. Before proceeding, may I check and confirm if you are accessing your email directly from Outlook or you are also using the web access for Outlook?
