How should a small office set up Microsoft Teams?
Start with one team for the whole office and a few channels by topic, such as jobs, admin and scheduling. Use chats for quick one-to-one questions and channels for anything the team should be able to find later. Files posted in a channel are stored in the team's SharePoint site. Business plans allow meetings of up to 300 people.
The short version
- One team for the whole office is enough to start. Add more only when a group really works apart.
- Channels hold topics. Chats hold quick conversations between a few people.
- Files posted in a channel live in the team’s SharePoint site, not on anyone’s laptop.
- Guests from outside can join a team only if your admin allows it.
- Business plans allow meetings of up to 300 people.
What’s the difference between a team, a channel and a chat?
| What it is | Use it for | |
|---|---|---|
| Team | A group of people with shared channels, files and a calendar | The office, a department, or a long-running client project |
| Channel | A topic inside a team, with its own posts and files folder | Jobs, scheduling, admin, a specific site or client |
| Chat | A private conversation between 2 or more people | Quick questions, “are you free at 3?” |
Microsoft’s Teams limits page explains how they’re stored. Each team has a SharePoint site, and each channel gets a folder in it. Files shared in a one-to-one or group chat are stored in the sender’s OneDrive instead. That difference matters when someone leaves; see where files live.
Behind the scenes, every team is a Microsoft 365 group, per Microsoft’s compare groups page. That’s why a new team also gets an email address and a calendar.
How do I create a team?
These steps follow Microsoft’s create a team page for the current Teams app on a computer:
- In the left bar, select Chat. If you use the separate view, select Teams instead.
- Select New items above your list of chats and channels.
- Select New team.
- Name the team and add a short description.
- Choose Private (only people you add) or Public (anyone in your organization can join).
- Name your first channel.
- Select Create, then invite people to the team.
You become the team owner. Microsoft notes that the first channel used to be called “General,” that you now name it yourself, and that it can’t be deleted or archived. Your organization may limit who can create teams.
How should a small office lay it out?
A simple starting layout for a team of 5 to 20 people:
- Team: the business name, Private, with everyone in it.
- Channels: one for announcements, one for scheduling, one for jobs or clients, one for admin and billing.
- Private channel for anything only owners should see, such as payroll questions.
Keep the number of channels small. People stop reading channels they don’t need. Microsoft allows up to 1,000 channels per team, but a small office rarely needs more than a handful.
What about meetings and calls?
- Business Basic, Standard and Premium allow online meetings for up to 300 people, per Microsoft’s limits page.
- A video or audio call started from a chat can include up to 20 people.
- A group chat can hold up to 250 people.
- Meeting recordings stop at 4 hours and restart automatically.
- Microsoft’s Teams service description lists webinars and town halls (Teams events) for Business Standard and Premium. Teams live events were retired on June 30, 2026.
Calling regular phone numbers from Teams needs extra Teams Phone licensing and a calling plan. It isn’t included in the Business plans by default.
How do guests work?
You can add people from outside your company to a team as guests, but only if your admin has allowed guest access. Guests sign in with their own email address. Add guests to a dedicated channel or team, not to the one where you talk about pay or pricing.
Why does the layout matter?
Teams replaces a lot of internal email. If the layout is messy, important notes vanish into chats nobody can find later. If it’s tidy, a new hire can scroll back through the jobs channel and learn how things are done.
What are the common mistakes?
- A team for everything. Ten half-empty teams are harder to follow than one team with clear channels.
- Doing real work in chats. Decisions in a two-person chat are invisible to everyone else. Post them in the channel.
- Sharing files by chat. They end up in one person’s OneDrive. Post them in a channel instead.
- Public teams by accident. Anyone in the organization can join. Pick Private unless you mean it.
- Buying a plan without Teams. Since April 2024, Business plans are also sold without Teams. See which plan your team needs.
What if you can’t create a team?
Your organization may restrict who can create teams. Ask your admin. If Teams is missing entirely, check whether your plan is a version without Teams.
How much does it cost, and how long does it take?
Teams is included in Business plans that come with Teams. Setting up a first team and its channels takes about half an hour. Getting everyone to use it consistently takes a few weeks of gentle reminders.
How does E-3 handle this?
When we set up Microsoft 365 for a client, we create the account in the client’s name, with E-3 added as a user.
