An interactive hands-on Copilot lesson on Cowork basics: it reframes Cowork as a coworker with desk access, walks install and folder connection, has the learner classify actions by permission level (automatic, asks first, never), and pick a good first task.
Copilot Mastery · Cowork · Lesson 01 · ProStep 1 of 6 · ~11 min
A real coworker on your desk.
Cowork turns the Microsoft 365 Copilot Frontier Firm tenant into a real working environment — AI that reads your files, runs scripts, drafts documents, and automates the tedious stuff. It's not a chat upgrade; it's a different category.
Update · July 2026: Copilot Cowork is now generally available worldwide — no longer limited to the Frontier program. You define the task; Cowork plans, executes, and delivers it, grounded in the systems your business already runs on. Usage-based billing in Copilot Credits went live July 1 — set your caps first (see what Copilot costs).
You'll learn what it is, how to connect a folder, the permission model that keeps you in control, and your first useful task. About 11 minutes.
A coworker with desk access — not a smarter chatbot
The difference between Cowork and regular AI chat is asking a consultant for advice over the phone vs. handing them a laptop with your files on it. Same intelligence, completely different leverage. Cowork reads and edits files in folders you connect, runs code in a sandbox, and calls connected apps — so your prompts change: you delegate outcomes, not request answers.
Your call
You want a report in your folder summarized. Which is the Cowork way to ask?
01 · Install and connect a folder
Setup
The step most people miss is connecting a folder — without it, Cowork has nothing to work on.
Setup sequence1. Confirm your tenant is in the Frontier Firm program (IT enables it)
2. Open Microsoft 365 Copilot Chat
3. Toggle on the Cowork capability when prompted
4. Connect a OneDrive/SharePoint folder — a specific working folder, not the root
5. Test: "list the files in my connected folder"
6. See your real file names? You're set up.

Which folder do you connect?
02 · The permission model
Stay in control
Cowork keeps you in control: some actions are automatic, some always ask first, and a couple are off-limits entirely. Set the permission you'd expect for each — then check.
Read a file in your connected folder
Run code in its Linux sandbox
Delete a file
Send an email through a connected app (Outlook)
Read your saved passwords or browser cookies
03 · Your first useful session
Do real work
The fastest way to get it: hand Cowork a real task that would take you 30+ minutes by hand. Don't start with "hello."
A strong first taskLook through my connected folder. Find documents from the last 90 days that look like meeting notes or call transcripts. For each, give me the date, a 2-sentence summary, and any action items that don't seem done yet. Present it as one markdown table I can copy.

Lesson complete
You've got the mental model, the setup, the permission model, and a first task — everything to start delegating real work.
Your first 60 minutes
Install Cowork, connect one specific folder, and run the "find recent meeting notes" task. The first time a table appears with real summaries from your real files, you'll feel why this is a different category from chat.
What you can do now
Set up Cowork, connect a specific working folder, delegate outcomes instead of asking questions, know which actions need permission, and pick a first task that proves the value.
