If you searched for "Office 365 Personal vs Business", you're in the right place. Microsoft retired the Office 365 name for most plans some years ago, and everything is now sold under the Microsoft 365 brand. The question underneath hasn't changed though: can a small business get by on a home subscription, or does it need a proper business plan?
We get asked this constantly, usually by a sole trader or a growing team that started on a Family subscription and now has five people sharing files through personal OneDrive accounts. This guide lays out the real differences so you can make the call with your eyes open.
The two families of plans in 2026
Home plans (consumer)
Microsoft's consumer line-up is aimed at individuals and households. It currently includes:
- Microsoft 365 Basic: extra OneDrive storage and ad-free Outlook, without the desktop Office apps.
- Microsoft 365 Personal: the desktop apps (Word, Excel, PowerPoint, Outlook, OneNote), OneDrive storage and Copilot features with monthly usage limits, for one person.
- Microsoft 365 Family: the same as Personal, shared with up to six people.
- Microsoft 365 Premium: a higher consumer tier that adds much higher Copilot usage limits and more advanced AI features. It replaced the standalone Copilot Pro subscription.
Every one of these is tied to a personal Microsoft account (an Outlook.com, Hotmail or similar login) owned by the individual, not by a company.
Business plans (commercial)
Microsoft's business plans are designed for organisations of up to 300 users (larger organisations move to the Enterprise E-plans). The core line-up is:
- Microsoft 365 Business Basic: business email on your own domain, Teams, SharePoint, OneDrive, and the web and mobile versions of the Office apps.
- Microsoft 365 Business Standard: everything in Basic plus the full desktop Office apps.
- Microsoft 365 Business Premium: everything in Standard plus the security and device management layer: Microsoft Intune, Microsoft Entra ID P1 (including Conditional Access), Microsoft Defender for Business and Microsoft Purview information protection.
- Microsoft 365 Apps for business: desktop apps and OneDrive only, with no business email, Teams or SharePoint.
Two newer wrinkles are worth knowing about. First, in many markets these plans are now sold in versions with and without Microsoft Teams, so check which one you're buying. Second, business users get Microsoft 365 Copilot Chat, and the full Microsoft 365 Copilot experience inside the Office apps is available for small businesses as an add-on or in bundled "with Copilot" versions of Business Standard and Business Premium.
The apps are largely the same. What you're really choosing between is who owns and controls the accounts and data: an individual (home plans) or your organisation (business plans).
Side-by-side comparison

|---|---|---|
| Intended for | Individuals and households | Organisations, from sole traders up to 300 users |

| Collaboration | OneDrive sharing | Teams (where included), SharePoint sites, shared calendars, guest access |
| Admin control | None beyond the subscription owner | Central admin centre: create, suspend and offboard users, reassign licences |
| Security controls | Individual MFA and account settings | Enforceable MFA, security defaults, and in Business Premium, Conditional Access, device management and endpoint protection |
| Data ownership | Stays with the person when they leave | Stays with the business when a staff member leaves |
| AI | Copilot features with consumer usage limits (higher on Premium) | Copilot Chat included; Microsoft 365 Copilot available as an add-on or bundle, grounded in your work data |
Licensing: the part people skip
Microsoft positions Personal and Family as home plans. Its guidance is that business use requires a commercial licence, which is what the Business and Enterprise plans provide. The consumer terms have caused some debate over the years, but the practical reality is simple: if you're running a registered business, paying staff or handling client data, a business plan is the licence Microsoft intends you to be on, and it's the one an auditor, insurer or client security questionnaire will expect to see.
Why the business plans win for any real business
1. The business owns the data
This is the big one. On a home plan, the files, mailbox and OneDrive belong to whoever owns the Microsoft account. When that person leaves, their data can walk out with them, and you have no admin console to stop it. On a business plan, accounts live in your organisation's tenant. You can block sign-in, convert a mailbox to a shared mailbox, hand a OneDrive to a manager and reassign the licence in minutes.
2. Professional email on your domain
Business plans give every user an Exchange Online mailbox on your own domain, with shared mailboxes for addresses like accounts@ or info@. That also means you can set up SPF, DKIM and DMARC properly, which protects your domain from being spoofed. We cover that in more detail on our DMARC & phishing protection page.
3. Collaboration built for teams
SharePoint and Teams give each department or project a shared space with version history, co-authoring and permissions that belong to the team, not to one person's OneDrive. If you're unsure where files should live, our guide to SharePoint vs OneDrive explains the rule of thumb we use with every client.
4. Security you can actually enforce
On a home plan, security is up to each individual. On a business plan you can enforce multi-factor authentication for everyone. Business Premium goes much further: Conditional Access policies, Intune device management, Defender for Business endpoint protection and sensitivity labels. These map directly to several ACSC Essential Eight controls, which our Essential Eight TL;DR walks through.
5. AI grounded in your business
Home plans include Copilot features, but they work against your personal files. Microsoft 365 Copilot on a business plan can work across your organisation's email, meetings, chats and SharePoint content, respecting the permissions already in place. That's powerful, and it's also why tidy permissions matter before you turn it on.
So which plan should you choose?
- Household, study or personal projects: Personal or Family is the right fit.
- Sole trader who mainly needs email on their domain and web apps: Business Basic.
- Small team that works in the desktop Office apps every day: Business Standard.
- Any business handling client, financial or health information: Business Premium. We generally recommend it as the baseline, because the security tooling is what makes a Microsoft 365 environment defensible.
Mixing plans in one tenant is normal. A warehouse user might sit on Business Basic while the office team is on Business Premium, provided the security requirements you need are covered for everyone who touches sensitive data.
You're not alone, and it's fixable. Moving from personal accounts into a business tenant involves migrating mailboxes and OneDrive content, setting up your domain and re-sharing files from SharePoint. Plan it as a small project rather than a Friday afternoon job.
How synfo can help
We set up, migrate and manage Microsoft 365 business tenants for Australian organisations, from licence selection through to security hardening and ongoing support. If you're moving off personal accounts or off another platform (see our Google Workspace to Microsoft 365 migration guide), our professional services team can scope it. Once you're in, our managed IT plans keep the tenant secure, licensed correctly and backed up with Microsoft 365 backup.
