Microsoft Teams Download: How to Install Teams for Business

Where to Download Microsoft Teams

The Teams desktop app can be downloaded directly from microsoft.com/en-gb/microsoft-teams/download-app. There is no charge to download the application — the cost comes from the Microsoft 365 licence that enables the business features. You do not need to be an IT administrator to download Teams; any user can install it themselves from the Microsoft website.

For businesses managing multiple devices, there are several deployment options that avoid relying on individual users to download and install the app themselves.

Available Versions

Desktop App (Windows and Mac)

The desktop application provides the full Teams experience. This is the version recommended for business users. It supports all features including Teams Phone calling, breakout rooms, background blur, live transcription, and meeting recording. It runs as a native application, meaning performance is better than the browser version and you get features like system notifications, keyboard shortcuts and the ability to answer calls when Teams is running in the background.

The Windows version installs per-user by default (no admin rights required), though IT administrators can deploy an MSI installer across the organisation. The Mac version installs in the Applications folder and requires standard macOS permissions.

Web App (Browser-Based)

Teams can be accessed at teams.microsoft.com without installing anything. The web version supports most features including meetings, chat and file collaboration. Some functionality — including certain calling features and background effects — may be limited depending on your browser. Microsoft Edge and Chrome provide the best Teams web experience; Firefox and Safari have some limitations.

Mobile App

Teams is available on iOS (App Store) and Android (Google Play). The mobile app is well-suited for staying connected on the move — joining meetings, checking messages and accessing files. Managing meetings, settings or admin functions is better handled on the desktop.

System Requirements

Windows

Teams requires Windows 10 or later (64-bit). The app needs at least 4GB of RAM, though 8GB is recommended for running Teams alongside other business applications. Processor: 1.6GHz dual-core or higher. For video calling, a webcam with at least 720p resolution is recommended.

Mac

Teams supports macOS 12 (Monterey) and later. Apple Silicon (M1/M2/M3) and Intel Macs are both supported. Requirements are broadly similar to Windows in terms of RAM and processor. Microsoft maintains a current list of supported macOS versions on their documentation site.

Browser

Teams web works best on Microsoft Edge (Chromium) and Google Chrome. Safari on Mac supports the core features but may lack some meeting functionality. Internet Explorer is not supported.

Deploying Teams Across Your Organisation

For businesses with more than a handful of staff, it's worth setting up a managed deployment rather than asking users to self-install.

Microsoft Endpoint Manager (Intune)

If you're using Microsoft Intune for device management (included in Business Premium, E3 and E5), you can deploy Teams silently to all managed devices without user intervention. This ensures consistent versioning and avoids situations where some users are on outdated versions.

Group Policy and MSI Installer

On-premises or hybrid environments can deploy Teams using the Teams MSI installer alongside Group Policy. This is common for businesses still using Active Directory. The MSI installs Teams for all users on the machine, and you can control update behaviour through group policy settings.

Microsoft 365 Admin Centre

The Microsoft 365 Admin Centre allows administrators to manage Teams settings and licences centrally. When users sign in with their Microsoft 365 credentials on a new device, they can download and configure Teams from the My Apps portal or microsoft.com.

Updating Teams

The Teams desktop app updates automatically in the background. Users typically see update notifications and can apply them without IT involvement. For IT-managed environments using Intune or SCCM, update rings can be configured to control when new versions are deployed across the organisation — useful for testing updates before a broad rollout.

Common Download and Installation Issues

Admin Rights

The standard Teams installer does not require admin rights on Windows, which makes self-service installation straightforward. If users are encountering permission errors, check that the device's security policy isn't blocking user-level application installs.

Proxy and Firewall Configuration

Teams requires access to specific Microsoft URLs and IP ranges. If your business uses a web proxy or strict firewall, Teams traffic may be blocked or degraded. Microsoft publishes the full list of required endpoints for Teams at docs.microsoft.com. This is one of the more common causes of Teams call quality issues in office environments.

Multiple Accounts

Teams supports multiple accounts in the desktop app, which is useful for consultants or those working across more than one organisation. You can switch between accounts without signing in and out, though some features behave differently when running multiple accounts simultaneously.
