Microsoft Teams Download: How to Install Teams for Business

If you run an IT estate of any size, the question is rarely "where do I click download" — it is "how do I get every device on the same version, locked down, without chasing 80 people to install an app". This guide covers both: the quick self-install route, and the managed deployment route a managed Microsoft 365 team would actually use.

Where can you download Microsoft Teams?

The Teams desktop app downloads directly from Microsoft at microsoft.com/en-gb/microsoft-teams/download-app. The download itself is free on every platform. You do not need administrator rights and you do not need to be in IT — any user can install it from the Microsoft website in a couple of minutes.

The cost is never the app. It is the Microsoft 365 licence behind it that enables scheduled meetings, recording, and Teams Phone. Business Basic starts at £4.60/user/month and includes Teams, according to Microsoft's UK pricing.

• Self-install — fine for a handful of users or a quick trial.
• Managed deployment — the right answer once you are past ~10 staff, because it controls versioning and security centrally.

Which version of Teams should your business use?

Use the desktop app for daily business use. It carries the full feature set — Teams Phone calling, background effects, live transcription and proper notification handling. The web app covers chat and meetings when you are on a borrowed machine; the mobile app is for staying reachable, not for running meetings.

The desktop app runs natively, so call quality, notifications and keyboard shortcuts all behave properly. The web version works best in Microsoft Edge or Google Chrome; Safari and Firefox lose some meeting and background-effect functionality. If your team relies on Teams Phone calling, the desktop app is non-negotiable.

What are the system requirements for Microsoft Teams?

Teams runs on Windows 10 or later (64-bit) and macOS 12 (Monterey) and later. Plan for 4GB of RAM as a floor and 8GB if Teams runs alongside other business apps. For video, a 720p webcam is the practical minimum. Microsoft maintains the current supported-version list in its technical docs.

Internet Explorer is not supported, and Safari supports core features only. Because Microsoft retires older OS versions on a rolling basis, confirm against the current Teams requirements on Microsoft Learn before a large rollout — a device that meets spec today may fall off the supported list within a year.

How do you deploy Teams across your organisation?

For anything past a handful of staff, deploy Teams centrally rather than asking users to self-install. Centralised deployment keeps every device on the same version, removes the "I'm on an old client" support tickets, and lets you apply security policy at the same time. There are three routes, depending on how your estate is managed.

Microsoft Intune

If you manage devices with Microsoft Intune — included in Business Premium, E3 and E5 — you can push Teams silently to every managed device with no user action. This is the cleanest option: consistent versioning, no admin-rights friction, and policy applied centrally.

Group Policy and the MSI installer

On-premises or hybrid environments running Active Directory can deploy the Teams MSI alongside Group Policy. The MSI installs Teams for all users on the machine, and update behaviour is controlled through policy settings — the familiar route for AD-based estates.

Microsoft 365 Admin Centre

The Microsoft 365 Admin Centre centralises Teams settings and licence assignment. When a user signs in to a new device with their Microsoft 365 credentials, they can pull Teams from the My Apps portal. Pair this with Teams security hardening so external access and guest policies are set before users arrive.

How does Microsoft Teams update?

The Teams desktop app updates itself automatically in the background. Most users simply see a notification and apply it without involving IT. In a managed estate, you take control of that timing instead of leaving it to chance.

Using Intune or SCCM, you can configure update rings — test a new version on a pilot group, confirm nothing breaks, then release it to everyone. That staged approach matters most where Teams carries phone calls, because a bad update on a calling client is a business-down problem, not a cosmetic one. If calling is central to you, plan updates the same way you would for Teams Direct Routing infrastructure.

What are the most common Teams download and install problems?

Three issues account for most Teams install and quality complaints: permission policy, network configuration, and multi-account confusion. None are difficult to fix once you know where to look — and most disappear entirely under a properly managed deployment.

• Admin rights — the standard Windows installer is per-user and needs no admin rights. If users hit permission errors, a device security policy is blocking user-level installs; fix the policy rather than handing out local admin.
• Proxy and firewall — Teams needs specific Microsoft URLs and IP ranges. A strict proxy or firewall that blocks them is the single most common cause of poor call quality. Microsoft publishes the full required-endpoints list on Microsoft Learn — allow them explicitly.
• Multiple accounts — the desktop app supports several accounts for people working across organisations, but some features behave differently when accounts run side by side. Confirm which tenant a meeting belongs to before joining.

Getting Teams installed is the easy part. Getting it deployed consistently, secured, and tuned for clean call quality across every site is where most SMEs lose time — which is exactly the work our managed IT support team takes off your plate.
