Microsoft 365 Business Basic vs Standard vs Premium: which plan fits your office

Microsoft 365 has three main plans for small businesses: Business Basic, Business Standard and Business Premium. The names do not tell you much, and the comparison charts list dozens of features most offices will never touch. The result is that many businesses either overpay for licenses they do not use or underbuy and miss the security tools they need.

Here is what actually separates the three plans, in plain terms, and how we help small offices choose.

What all three plans have in common

Every Business plan is designed for organizations of up to 300 users and includes the core cloud services:

• Business email through Exchange Online, with your own domain and shared calendars.
• OneDrive cloud storage for each user, 1 TB per person.
• SharePoint for shared company files and team sites.
• Microsoft Teams for chat, meetings and calls, depending on the version you buy.
• Web and mobile versions of Word, Excel, PowerPoint and Outlook.
• Basic security such as MFA and standard spam and malware filtering.

Microsoft adjusts plan contents, add-ons such as Copilot, and prices from time to time. Check the current plan pages or ask your provider before buying, rather than relying on an old comparison chart.

Business Basic: cloud services, web apps

Basic is the entry plan. People get email, Teams, OneDrive and SharePoint, but they use Office apps in a web browser or on a phone and tablet. There are no installable desktop versions of Word, Excel or Outlook.

Basic works well for:

• Staff who mainly need email and Teams, such as field workers or front desk roles.
• Seasonal or part-time users.
• Offices that already own perpetual Office licenses and just need cloud email and storage.

Business Standard: adds the desktop apps

Standard includes everything in Basic plus the full desktop Office apps on Windows and Mac, installable on several devices per user. For anyone who lives in Excel or needs the full version of Outlook, this is usually the minimum.

The catch is that Standard does not add much security beyond Basic. You get the same email filtering and the same sign-in controls. For many offices that is the real gap.

Business Premium: adds security and device management

Premium includes everything in Standard plus a set of security and management tools that would cost more to buy separately:

• Microsoft Entra ID P1, which enables Conditional Access. You can block sign-ins from unmanaged devices or unexpected countries and require stronger checks for risky logins.
• Microsoft Intune, for managing and securing Windows PCs, Macs and phones, pushing settings and wiping lost devices.
• Microsoft Defender for Business, endpoint protection with detection and response for your computers.
• Defender for Office 365, which adds protection against malicious links and attachments in email.
• Information protection tools such as sensitivity labels, data loss prevention and email archiving.

Conditional Access in particular helps against modern account attacks, like those described in our post on MFA fatigue and token theft in Microsoft 365.

When Premium is worth it

We usually recommend Premium when any of these apply:

1. You handle sensitive client data, such as health, legal, financial or personal records.
2. Staff work from home or on the road with company laptops.
3. You want to manage devices centrally and be able to wipe a lost laptop.
4. Your cyber insurance application asks about MFA, endpoint protection and device management.
5. You have had a compromised mailbox or invoice fraud attempt before.

If you have a regulatory or insurance requirement, confirm the specific obligations with your adviser or insurer. Licensing gives you the tools, but they still have to be configured to do any good.

Mixing plans in one office

You do not have to buy the same plan for everyone. A common setup for a small office:

1. Premium for owners, managers, finance staff and anyone with remote access.
2. Standard or Premium for staff who need desktop apps.
3. Basic for light users who only need email and Teams.

Keep in mind that security policies only protect the users licensed for them. If one unprotected account can approve payments, that account becomes the weak point. Review licenses once a year, and remove licenses for former staff promptly.
