You can create server-side rules via “Settings → Mail → Rules” in Outlook Web. While more limited than Outlook for Windows client-side rules, they're fine for simple "move emails from x to folder y"-type rules, and are particularly useful for people like me who rarely use Outlook at all. You can also create server-side rules in the Exchange admin center if you have access.
