The short answer: Probably not for everyone. Your Microsoft 365 plan likely already includes a free version of Copilot Chat. The full version of Copilot, which works inside your email, files, and Teams meetings, costs extra per user. It’s worth paying for the people whose workday runs through those apps, and only after you’ve cleaned up who can see what.
What you already have
If your business uses Microsoft 365, your team can likely use Microsoft 365 Copilot Chat with their work accounts at no extra cost. It’s a secure AI chat for questions, drafting, and summarizing what you paste in or upload.
What it doesn’t do is work across your business: your inbox, your SharePoint files, your Teams meetings. That’s the paid version.
What the paid version adds
Microsoft 365 Copilot works inside Outlook, Word, Excel, PowerPoint, and Teams, using the files and conversations you already have access to. That’s where the time savings show up:
- Summarizing a long email thread and drafting the reply
- Recapping a Teams meeting you missed, with action items
- Turning a pile of notes into a first-draft document or slide deck
- Pulling numbers out of a spreadsheet in plain English
Since July 2026, Microsoft sells it bundled into new “Business Standard with Copilot” and “Business Premium with Copilot” plans, as well as an add-on to the plan you already have. Either way, it’s licensed per user, so you don’t have to buy it for the whole company.
Who on your team actually needs it
The people who live in Microsoft 365 all day get the most from it: executives, office managers, client-facing staff, and anyone buried in email and meetings. People whose work happens mostly in other systems, or who mostly need help with long documents or open-ended research, may get more from a different tool, or from the free Copilot Chat they already have.
The smartest first step is to license Copilot for a small group, measure what it saves them, and then decide.
The step most businesses skip
Copilot can see everything a user has access to. In a lot of businesses, that includes old shared folders, files shared with “Everyone,” and documents that should have been locked down years ago.
Before you turn it on, review your file permissions and put a written AI use policy in place. That isn’t a Copilot problem. It’s a housekeeping problem that Copilot makes visible.
Frequently asked questions
Is Copilot included in Microsoft 365?
A free version, Copilot Chat, is available to most business users with a work account. The full Microsoft 365 Copilot, which works inside your apps and files, costs extra per user.
Do I have to buy Copilot for everyone?
No. It’s licensed per user. Most businesses get the best results by starting with the people who spend the most time in email, meetings, and documents.
Is Copilot safe to use with client data?
It only shows each user what they can already access, so it’s as safe as your permissions. Clean up file sharing and set an AI use policy before you roll it out.
