Microsoft 365 Business Basic is Microsoft’s entry-level business plan. It gives you email on your own domain, Teams, OneDrive and SharePoint, with Word, Excel and PowerPoint in their web and mobile versions. It leaves out two things: the apps installed on the computer, and the security layer that protects accounts, email and devices. The first shows straight away. The second only shows on the day something goes wrong.
What Business Basic includes
Each user gets a 50 GB mailbox, 1 TB of OneDrive storage, Teams for meetings and chat, and SharePoint for the team’s shared files. Online meetings can hold up to 300 people.
For office work, everything runs in the browser or in the phone and tablet apps. Microsoft’s plan table is unambiguous: the desktop apps are not part of Business Basic.
For someone who writes email, reads documents and joins meetings, that is often enough day to day.
What’s missing for getting the work done
Excel for the web handles most everyday spreadsheets. It can’t create or run VBA macros, and analysis tools such as Goal Seek and Solver aren’t there, so a pricing or financial tracking workbook built on them stops working in the browser.
The people who need these find out quickly. They then install a separately bought copy of Office, or sign in with a personal account. Either way, company files start living outside the environment you control.
What’s missing for protecting the business
This is the part that weighs most, and it doesn’t appear on the invoice. Microsoft’s security overview for Microsoft 365 for business shows Business Basic and Business Standard with exactly the same protection: security defaults, baseline email filtering and rudimentary phone management.
Security defaults require a second factor at sign-in, which is a good start. They allow no rules specific to your business. You can’t say “this account only signs in from our laptops”, or block a sign-in from a country where nobody works. We explain why a second factor alone is no longer enough in Is multi-factor authentication enough?
Also missing: links checked at the moment of the click, and attachments opened in isolation first, which stop a good share of scam and phishing mail. And nothing lets you set up, lock or wipe a laptop remotely, or keep company data apart on a personal phone.
These protections come with Business Premium, which also includes the desktop apps. We compare the two higher plans in Business Standard or Business Premium: which one?
Business Basic: who is it for, then?
For a business with client files, online banking access or personal data, Business Basic isn’t the right foundation, even if nobody needs Word installed. Its lower price comes precisely from what it doesn’t protect.
The real question often concerns only a few people: a board member, an occasional consultant, seasonal staff. For them, a lighter licence such as Microsoft 365 F3 can fit, under the usage terms Microsoft sets. It comes with a smaller mailbox and OneDrive, Office apps on the web and on phones, and the same account protection as the rest of the team. Attackers look for the least protected account, so keeping everyone at the same level closes that door.
Mixing Basic and Premium licences in one team does the opposite. Access rules only cover the accounts that hold a Premium licence, and the Basic accounts become the way in.
If you’re already on Business Basic
Moving to Business Premium needs no migration: email, files and teams stay where they are. The work is in configuring what Premium brings, then testing it so nobody gets locked out by mistake.
That is what our Cloud offer does: we set up this security layer and run it for you. If you’d like us to look after the team’s laptops as well, the Cloud and 360 comparison helps you place yourself. Both run on Business Premium.
