  • With such rapid growth has come a steeper learning curve, especially for users who are entirely new to Microsoft Teams and its growing list of features and third-party integrations.
  • In this ultimate guide for Microsoft Teams, we’ll explain the core components of the platform, how to start communicating and collaborating, how Teams Apps work, take a look at pricing, and much more.


Microsoft Teams is a success story almost nobody saw coming.

From a platform built on the foundation of Skype that many people thought would fade into obscurity to a productivity powerhouse boasting 250 million daily active users – Microsoft Teams has proven itself… and then some.

It’s certainly true that Teams received something of a leg-up in terms of adoption due to the global pandemic and work-from-home mandates, but the platform wouldn’t have reached these dizzy heights if it didn’t have the chops to back it up.

So, whether you’ve been using Teams for a while and you’re looking for a refresher, or this is the first time you’re reading about the platform – this ultimate guide is all you need to get started with Teams in 2021.

So let’s dive right in.

What is Microsoft Teams?

To make it easier to navigate, we’ll break this guide down into the various components of the platform so you can learn at your own pace.

Before that, though, let’s begin with the basics: what exactly is Microsoft Teams?

Originally launched in 2017, Teams aims to take everything you can do in a physical team meeting and bring it into a digital environment. That means everything from having a quick chat, making a phone call, scheduling a meeting, or collaborating on documents in real-time.

As the platform has evolved, Teams has grown to encompass larger-scale uses, including presentations and live events to thousands of people at once.

Accessibility is also central to the ethos of Teams, with the development team keen to make the app available on as many devices (and in as many different working conditions) as possible. As of 2021, dedicated apps for Microsoft Teams are available on the following devices:

  • Microsoft Windows (desktops, laptops, certain tablets)
  • macOS (desktops, laptops)
  • iOS (iPhones, iPads)
  • Android (smartphones and tablets)

The Microsoft Teams web app can also be accessed using modern web browsers such as Google Chrome and Mozilla Firefox.

With definitions done, let’s now take a closer look at each of the components of Microsoft Teams in a bit more depth.

Teams, Channels, and the Activity Tab

The first aspect of Microsoft Teams we’ll look at is the glue that holds the whole system together: channels and teams.

Think of these as workspaces within the app from where your work gets done. They could either be based on internal groups – like Marketing or Sales – or on specific projects – like certain products or services.

What’s the difference between a team and a channel? Here’s the lowdown.

Teams, as the name suggests, are the building blocks of the Microsoft Teams experience. They are best used to represent the different departments within a business – Marketing, Sales, IT, and so on – and sit at the top of the hierarchy. Whenever teams are created, the system will also create back-end assets – such as a SharePoint site – within Microsoft 365 to host files, manage users, and more.

Channels are sub-teams. They sit one level down from teams in the platform’s hierarchy and can be created for almost any purpose, including product launches, marketing campaigns, business admin, and more. When teams are initially created, a ‘General’ channel will also be added to the group by default. Beyond this, admins or users with the correct permissions can add as many channels as they like, then add other users to these channels. Within channels, users can start conversations, upload files, and communicate with others – a bit like a social media feed. Users can use features like @tagging to notify others when they’d like them to join the conversation.

You can access any of your teams or channels by clicking the Teams button in the left-hand navigation menu, but there’s another way to get a quick overview of recent activity in Microsoft Teams.

At the very top of the left-hand menu is the Activity button, and by clicking here you can access an up-to-date feed of all of your Team's goings-on. No matter which team or channel the specific items have taken place within, you’ll see them in a chronological list and can click them to jump straight to the relevant channel. It’s a quick way to save some time and jump straight into what matters when you start your day.

Tabs and Microsoft Teams Apps

The next feature we’ll look at is found within every channel within Microsoft Teams, and it’s known as tabs.

Whenever you create a channel in Teams and click on it, you’ll see three default tabs next to the title in the main content window:

  1. Posts show all of the activity within the channel in question, including any ongoing conversations and posts along with links to any attached files.
  2. Files provide a summary of all of the files which have been shared within this channel and that are stored within the corresponding SharePoint site. That could be anything from PDFs and Word documents to Excel spreadsheets and image files.
  3. Wiki is a convenient place to format essential information for anyone using the channel. For example, you might use the Wiki area to describe the purpose of the channel or list a few rules for users to follow when contributing to it.

Along with the default tabs which are included with any new channel you add to Teams, you can also add custom tabs, also known as Microsoft Teams Apps. These are a way to enhance Teams with new functionality – many of which are from third-party developers.

There are two different ways to add a Microsoft Teams app:

  1. From any of your Teams channels, click the ‘plus’ icon next to your existing tabs, then select the app you’d like to add to the channel from the library of over 700 Teams apps. The new tab will appear for all members of the channel and they’ll be able to use it to engage with the app or access the relevant content.
  2. Click the Apps button at the bottom of the left-hand navigation menu, then, again, select the app you’d like to add to Teams. This type of app will appear as a new icon on the left-hand menu, and not all apps are currently supported for this type of integration.

You can browse the many hundreds of Microsoft Teams apps on Microsoft’s website right now, but here’s a glimpse of the types of functionality you’ll be able to unlock using this feature:

The list does go on. With so many millions of active users on Teams, it’ll come as no surprise that developers are eager to integrate with the Teams platform as soon as possible. That means that, if there’s a third-party app you use a lot within your company, there’s a good chance you can use it as an embedded app in Teams – it’s certainly worth a look!

Chat and Meetings

It may go without saying, but central to the concept of Microsoft Teams is communication.

To offer a complete end-to-end service, the platform needs to provide communication tools to suit multiple environments and use cases – and that’s exactly what you get with Teams.

On the left navigation bar in Teams, you’ll see a Chat button. From here, you can start a text conversation with anyone inside your organization. You can even chat with external users if an admin has added them as a user within Teams.

Importantly, any conversations held within the Chat area of Teams will be private to you and the other person – they are not group conversations, which can be found either by clicking on the Activity button on the left-hand menu or by clicking into a team or channel directly.

Next up, let’s talk about one of the core features of Microsoft Teams, which is of course the meetings themselves.

It’s here where that deep integration with Microsoft 365 once again comes into play because there’s more than one way to schedule meetings with Teams:

  • Using the Microsoft Outlook app, any Teams user can click the New Teams Meeting button when creating a new invitation, which will automatically populate the email with the meeting link and more. This is the best method to use if you’re working with any external users.
  • Within Microsoft Teams itself, you can use the Meet Now button – accessible within any of your channels – to instantly begin a meeting with anyone who belongs to that channel or team.
  • Within Teams itself, look at the left-hand menu and click the Calendar button. From here you can view your schedule and, if you look in the upper-right corner, you’ll see the + New Meeting button. Give it a click and you can invite any other internal Teams users to a meeting at a time that suits you.

Because your Microsoft Teams account is seamlessly connected to your Microsoft 365 user profile, any meetings you schedule in apps like Outlook will automatically appear in Teams – and vice-versa.

Managing and Collaborating on Files

After communication, the next core piece of functionality in Microsoft Teams is collaboration.

In a world where hybrid working has become almost run-of-the-mill, it’s no longer a given that employees will be based together in single office spaces. Many businesses are moving to pure remote models – or simply hybridizing with a few days in the office and a few at home.

With disparate and unpredictable working arrangements, collaborating closely on projects – including on specific files and assets – becomes even more important.

With Microsoft Teams, you can view and edit the same document, spreadsheet, or presentation virtually alongside any number of your colleagues, all in real-time. Because Microsoft Teams comes with web versions of the core Office apps – Word, Excel, and PowerPoint – whenever you open a file that has been uploaded to Teams, you’ll be accessing the version hosted in the cloud. Likewise, if a team member opens that same document at the same time, they’ll be looking at the same file. But, unlike in the past, any changes you make won’t clash and cause problems but instead be updated instantly – just as though you were side by side working on the same computer.

Any supported file which is uploaded to a Teams channel, such as a Word doc or Excel spreadsheet, will be automatically added to the Files tab of that channel. When someone clicks to open the file either from the conversation in the channel feed or via the Files tab, they’ll be opening the Teams version of the file which is saved in the relevant SharePoint site on which this instance of Teams is built.

When collaborating on files in Microsoft Teams, your colleagues will be represented by small circular icons in the upper-right corner of the integrated Office app.

You’ll also notice a Conversation button within the web versions of these apps. Clicking this button will open the same conversation thread as the one in the main Teams channel. From here, you can use @tagging to bring other users into the conversation, then add comments to files directly which can be resolved by the relevant person once the change has been made.

How to start using Microsoft Teams today

Just as Microsoft Teams is built using a modular design philosophy, so too is access to the platform as flexible as possible.

If you want to start using Microsoft Teams right now and take it for a test drive, you can sign up for a basic Microsoft account and try all the platform’s core features absolutely free.

The catch? You’ll be restricted by several limitations which will mean you aren’t getting the most out of the experience. For example, you can’t benefit from the Exchange email integration, Outlook calendar syncing, file storage with OneDrive, enforced Multi-Factor Authentication for increased security, and more.

In our opinion, the free version of Microsoft Teams is a good way to get a feel for the app, but if you’re serious about using it within your business, you’ll want a Microsoft 365 business subscription.

Don’t worry – not only are these affordable, but they’re also (in our humble opinion) some of the greatest value subscriptions available to UK businesses.

  • Microsoft 365 Business Basic is the quickest way to get everything you need to support a small business or start-up. The Basic plan gives you access to Teams, the web versions of the Office apps, Exchange, OneDrive, and SharePoint. Business Basic starts at £3.80 per user per month, with an annual commitment.
  • Microsoft 365 Business Standard is the best choice for growing businesses that need a more comprehensive setup including business email and premium Office apps. This plan includes everything Basics does, but also delivers desktop versions of the Office apps, Outlook, Publisher, Access, and improved security. Business Standard starts at £9.40 per user per month, with an annual commitment.

For even larger-scale businesses or those who simply want the ultimate in business productivity, remote collaboration, and cyber security, we also recommend Microsoft 365 Business Premium. Be sure to ask a member of our team if this is something you’d like to know more about.
