Microsoft 365 Business Basic, the complete guide (2026)

Business Basic is Microsoft's cheapest cloud license for businesses with up to 300 users. It costs $6/user/mo and rises to $7 from July 1, 2026, a 17% increase.

In short: You get email, Teams, file sharing and web versions of Office (Word, Excel, PowerPoint, Outlook). You do NOT get desktop versions of Office apps, no advanced security and no device management.

Basic is Microsoft's attempt to compete with Google Workspace Business Starter. It covers the absolute basics: a business email on your own domain, a place to store files in the cloud and a meeting tool. Nothing more.

The complete list of what you get:

• •Exchange Online with 50 GB mailbox per user
• •Business email on your own domain (yourname@company.com)
• •Outlook only on web and mobile (no Outlook desktop)

• •Word, Excel, PowerPoint, OneNote, in the browser
• •Mobile apps on iOS and Android
• •No installed desktop versions on PC or Mac

• •Microsoft Teams with chat, meetings and calls (up to 300 meeting attendees, same limit as Standard and Premium)
• •OneDrive with 1 TB storage per user
• •SharePoint Online for file sharing and intranet
• •Microsoft Loop and Whiteboard

• •Microsoft 365 admin center
• •MFA (multi-factor authentication), free in all plans
• •Basic reporting

That's the foundation. Everything else, desktop Office, Intune, Defender, Conditional Access, Copilot, requires a larger plan or an add-on.

Microsoft prices all plans in US dollars but bills in local currency. The math:

• •$6/mo per user, which is $72/user/year

• •$7/mo per user, which is $84/user/year

• •Current price: $144/mo = $1,728/year
• •From 1 July 2026: $168/mo = $2,016/year

It's still the cheapest business license from Microsoft. For comparison, Business Standard costs $14/mo and Business Premium $22/mo from July 2026.

Basic makes sense for some specific profiles. I recommend it when:

• •Small businesses with under 5 employees that primarily use email and Teams
• •Consultants and freelancers who already have Microsoft 365 Personal/Family privately (and only need business email on their domain)
• •Frontline workers who primarily use mobile and shared devices (F3 is often better here, $10/mo with Intune, but only a 2 GB mailbox)
• •Receptionists and part-time staff who only need to read email and share files

• •Anyone working in Excel with formulas, macros or pivot tables
• •Anyone working offline (trains, planes, clients without guest wifi)
• •Businesses with GDPR-sensitive data that need Conditional Access or Intune
• •Anyone wanting to use Copilot (requires minimum Business Standard)

Businesses with over 10 employees rarely manage with Basic alone. There are typically 2-3 people who need real Excel or offline Outlook, and the license mix becomes messy.

This is the honest part. Basic has real limitations that often only become apparent after a few months:

No Office desktop apps You cannot install Word, Excel, Outlook or PowerPoint on PC or Mac. Only browser and mobile. That means no offline work, slower performance on large files, and limited formatting and feature options.

No device management (Intune) You cannot configure employee phones or laptops centrally. Bring-Your-Own-Device becomes difficult to manage securely.

No advanced security No Defender for Business, no Defender for Office 365, no Conditional Access. Only free MFA and basic Exchange filters. If you handle customer data, it's not enough.

Limited Exchange mailbox 50 GB sounds like a lot, but in an organization with many attachments or long correspondence threads it fills up. E3 and higher give 100 GB.

No Teams Phone You cannot use Teams as a phone system on Basic. That requires Standard + Teams Phone Standard add-on, or E5/E7.

The Copilot add-on doesn't work Microsoft 365 Copilot ($30/mo), which embeds AI into Word, Excel, Outlook and Teams, requires minimum Business Standard. The good news: Copilot Chat (web-based AI with commercial data protection) is free and works on Basic. But if you want AI inside the Office apps themselves, Basic is a blocker.

Most businesses we talk to need to upgrade within 12 months because needs grow. Here are the three realistic paths:

Upgrade to Business Standard ($14/mo from July 2026) The most important change: You get desktop versions of Office. For $7 extra per user per month, all employees get installed Word, Excel, Outlook, PowerPoint. For 20 employees, that's an extra $140/mo.

Upgrade to Business Premium ($22/mo, unchanged from July 2026) Everything in Standard plus Intune (device management), Defender for Business (anti-malware) and Conditional Access (policy-based access). For SMBs handling personal data or with compliance ambitions, Premium is often the right level. The difference from Basic is $16/mo, but you save money on separate security solutions.

Keep Basic but add selective add-ons E.g. Microsoft 365 Apps for Business ($8.25/mo) for 5 people who need desktop Office. It can make sense if only a small part of staff needs it, but typically it becomes administratively messy and even more expensive than putting everyone on Standard.

My recommendation: If you're growing or have 10+ employees, start with Standard. If you handle customer data, start with Premium. Basic is only the right choice when you're sure no one will need desktop Office daily.
