Dear Jessica Steele (HxSG),
Welcome to Microsoft Community.
After reading, I have a general idea of your problem. You wonder how to run ALL the rules in Microsoft Web Mail all at once.
From your description, your account seems to be a business account, because the rules are shared amongst members of your organization.
But the section you selected provides help for personal/family users, so I need to confirm with you again.
Would you mind please tell me is your account a personal account or business account?
Is your business email hosted on Microsoft Exchange server or has a Microsoft 365 subscription for business?
An important reference for distinction is: If you use this account to log in to Outlook web, which website do you use? "outlook.live.com" or "outlook.office.com"?
Looking forward to your timely response, I will continue to follow up on your question here.
Best Wishes,
Stan.L - MSFT | Microsoft Community Support Specialist
