What's the Difference Between Microsoft 365 Personal and Business?

Microsoft 365 Personal is licensed for individual, non-commercial use, while Microsoft 365 Business is licensed for companies and includes custom domain email, centralised admin controls, and features designed for multiple users working together.

Personal plans are designed for a single user, or a household under a Family plan, and come with an Outlook.com email address rather than a custom business domain. There is no admin centre to manage other users, and Microsoft's licensing terms explicitly state that Personal and Family plans are not intended for commercial or organisational use, even for a sole trader working alone.

Business plans include hosted email on your own domain through Exchange Online, along with Teams, SharePoint and an admin centre for managing users, permissions and security centrally. Security features scale with the plan chosen, from basic protections in Business Basic up to advanced device and identity management in Business Premium.

Personal and Family plans are capped at a small number of users and offer a fixed pool of OneDrive storage shared across accounts. Business plans provide 1TB of OneDrive storage per individual user, alongside separate SharePoint storage for shared team files, and support up to 300 users on the Business tier before a move to Enterprise plans becomes necessary.

Using a Personal licence for business purposes is not just against Microsoft's terms of service. It also leaves a business without the admin controls, compliance tools and centralised security that come with a proper Business plan. There is no way to enforce security policies across staff, manage leavers' access, or recover an account centrally if something goes wrong, which becomes a real problem the moment a business grows beyond one person.
