Why We Start Here
Most people who use Microsoft 365 every day have never had 30 minutes of someone explaining how the pieces fit together. They've just been handed a laptop, pointed at their inbox, and told to get on with it. That's how you end up with a desktop full of unnamed Word files, seventeen Teams you don't remember joining, and OneDrive full of duplicates of the same attachment.
The rest of this course will go much better if the map in your head matches what's actually on your screen. That's what this session is for.
We make sure the foundation underneath it is solid.
How Microsoft 365 Fits Together
Microsoft 365 is not one program. It's a bundle of programs that share the same account, the same storage, and (increasingly) the same AI. Understanding the shape of the bundle is half the battle.
- Your account is the centre. It's a work email address plus a password, often with two-factor authentication. Every app you use is logged in through that account.
- Cloud storage (OneDrive and SharePoint) is where your files live. Not on your laptop. On Microsoft's servers, synced to your laptop. This is a huge shift for anyone who still thinks of "the C drive" as home base.
- Communication (Outlook, Teams) is how you talk to other people, inside and outside your organisation.
- Documents (Word, Excel, PowerPoint, OneNote) is how you make things.
- Coordination (Planner, To Do, Forms, Lists) is how you organise the work.
- Copilot is the AI layer sitting on top of all of the above; it can see anything the account can see and help you do the work.
Your files don't live on your laptop anymore. They live in the cloud and sync down to your laptop. Once that clicks, sharing, versioning, and getting work onto a different device all make sense.
A Quick Tour of the Apps
You've probably used half of these. You might have avoided the other half. This is the whistlestop version; we'll go deeper in later sessions.
Outlook
Your inbox, calendar, and contacts. The hub most people spend most of their day in.
Teams
Chat with colleagues, run meetings, share files quickly. Channels for ongoing work, DMs for quick asks.
OneDrive
Your personal cloud folder. Files that are yours, and things-in-progress before you share them.
SharePoint
Shared storage for a whole team or a project. Underneath every Teams team is a SharePoint site.
Word, Excel, PowerPoint
The classic document apps, now with cloud saving by default and AI built in. We'll spend serious time in each.
OneNote
A digital notebook. Under-used, surprisingly good for meeting notes, project journals, and team knowledge.
Planner & To Do
Planner for team tasks on a board. To Do for your personal list. They talk to each other.
Forms
Quick surveys and intake forms. Results land in Excel or Power Automate.
Copilot
Sits on top of everything above. Summaries, drafts, analysis, search across your files. The Working with AI strand of this course is mostly Copilot.
A lot of people try to master everything and end up using nothing well. Pick the three or four you'll genuinely use — for most NT workplace roles that's Outlook, Teams, Word, and one of Excel or PowerPoint. Get confident with those. The rest becomes easy once the core four click.
Your Account, Your Identity
Your work email address is not just an email address. It's your identity across everything Microsoft. Your documents, calendar, Teams, chats, SharePoint permissions, and Copilot history are all linked to that one login.
What that means practically:
- When someone gives you "access" to a file or a site, they're adding your email address to a list. That's how permissions work.
- When you leave an organisation, your account is deactivated, and with it goes everything attached. Copy anything personal out before you go.
- When you share a link to a file, Microsoft checks the viewer's account against the permission list before letting them in. "Anyone with the link" is a different setting, and it's the one that causes accidental leaks.
- When Copilot "knows" things about your work, it's because it can see everything your account can see; nothing more, nothing less.
If someone gets into your work account, they get your files, your email, your Teams, and (if your org has it) Copilot acting on your behalf. Two-factor on this account is the most important setting in your entire working life. If your org hasn't turned it on yet, push for it.
Working Across Devices
One of the best things about M365 is that your workspace follows you. Your email on the desktop is the same email on the phone, the web, and the laptop at home. But the app experience isn't identical on each, and knowing the differences saves time.
Installed on your laptop
Most features, best for heavy work, work offline once files have synced.
office.com in a browser
Almost everything the desktop has, no install needed, handy when you're on a borrowed computer. Requires a connection.
On your phone
Simplified versions. Good for quick replies, reading on the go, approvals. Not where you write a 20-page report.
Sign out when done
Your browser may remember your credentials, which is useful on your own device and a real problem on a shared one.
The M365 desktop apps work fine without internet for anything already open or downloaded. Changes sync back up when you reconnect. This is different from Copilot, which needs a live cloud connection for every AI action. Plan heavy editing on the plane; save the Copilot work for when you're online.
What's Inside Your Tenant, What Isn't
This one matters for AI. Your organisation's M365 setup is called a "tenant". Think of it as a walled garden. Inside the garden: your documents, your Teams, your email, and any AI that runs through your organisation's Copilot licence. Outside the garden: the public internet, including free consumer AI tools like ChatGPT, Claude on the free tier, and Gemini.
Data that stays inside the tenant is covered by your organisation's agreements with Microsoft. Data that leaves the tenant is not.
- Microsoft 365 Copilot, when reading your documents, summarising your emails, or helping you write in Word. Actions stay within your org's Microsoft agreement.
- Teams chats and files within your organisation.
- OneDrive and SharePoint content your account has access to.
- The free web version of ChatGPT, Claude, or Gemini; pasting work content into those is sending it to a third party.
- External collaborators you share files with (their actions are governed by their organisation, not yours).
- Anywhere a link is set to "anyone with the link".
We'll come back to this in the Responsible Use session at the end of the course, but the mental model starts here.
Settings Worth Five Minutes
The defaults are mostly sensible. A handful of settings are worth changing once and then forgetting about.
- Confirm two-factor authentication is on. In portal.office.com, check your security info. Your workplace IT may have already forced this.
- Set OneDrive to sync automatically so your Documents, Desktop, and Pictures folders live in OneDrive. This is the single best protection against a laptop dying with your work on it.
- Turn on automatic cloud save in Office (File > Options > Save). Your work is saved every few seconds, and you can always roll back to a version from yesterday.
- Set Outlook to automatic reply mode when you're away so people get told rather than wondering. Takes 30 seconds the first time, protects your inbox forever.
- Make sure your mobile Authenticator app is set up so you can approve logins from your phone. It's much less painful than typing codes.
