Microsoft Teams is a unified communications and collaboration platform included with Microsoft 365 and available as a standalone app. It centralizes persistent group chat, threaded conversations, one-to-one messaging, video and audio meetings, cloud calling, shared file storage and application integrations into a single interface that runs on desktop, web and mobile. Teams is aimed at business, education and enterprise customers that need a single hub for teamwork across document collaboration, scheduling, communications and third-party services.
The platform integrates tightly with Microsoft 365 services such as SharePoint, OneDrive, Exchange (Outlook) and Office apps (Word, Excel, PowerPoint) so files and calendars work seamlessly inside conversations and channels. Administrators control security and compliance through Microsoft 365 and Azure Active Directory, which supports single sign-on (SSO), conditional access and device management.
Microsoft maintains both a free version for small teams and multiple paid tiers bundled with Microsoft 365 plans for businesses and enterprises. The product is also extensible: organizations can add apps, bots and automation through the Microsoft Teams developer platform and the Microsoft Graph API.
Microsoft Teams bundles several core feature areas designed for team productivity, communication and governance.
Microsoft Teams provides persistent chat organized by teams and channels, enabling subject-focused conversations and threaded replies. It supports one-to-one and group messaging with rich text, @mentions, message reactions and message pinning.
Teams supports scheduled and ad-hoc video meetings with features such as screen sharing, meeting recording, live captions, background effects and breakout rooms. Meetings integrate with Outlook for scheduling and with OneDrive/SharePoint for meeting recordings and file attachments.
Calling capabilities include PSTN calling (with add-on or carrier integration), call queues, auto attendants, voicemail and direct routing for integrating on-premises telephony. This makes Teams usable as a full cloud PBX replacement for organizations migrating from legacy phone systems.
File collaboration is built-in: files shared in channels are stored in SharePoint, one-to-one chat files are stored in OneDrive, and Office apps are available inline for co-authoring documents without leaving Teams. The platform also includes task and project apps such as Planner and To Do for basic task management.
Extensibility and integrations are a major part of Teams. The platform supports third-party apps, custom tabs, connectors, inbound/outbound webhooks, Microsoft Power Platform (Power Automate, Power Apps), adaptive cards, and bots built on the Microsoft Bot Framework. Developers use the Microsoft Teams developer platform and Microsoft Graph to automate workflows and extend Teams with custom solutions.
Security and compliance features include data encryption at rest and in transit, retention policies, eDiscovery, legal hold, audit logs and support for regulatory standards depending on Microsoft 365 plan level. Administrator controls let IT manage guest access, meeting policies, app permissions and device policies.

Microsoft Teams pricing ranges from $0 (free) to $57+/month per user. The free version supports small groups with basic chat, meetings and limited file storage. Paid tiers scale from low-cost standalone Teams plans for small businesses ($4.00/month) to Microsoft 365 business bundles that include Exchange email and Office apps ($6.00–$12.50/month for Business Basic and Business Standard), up to enterprise suites with advanced security and telephony ($36–$57+/month). Add-ons such as phone system licensing, audio conferencing, premium compliance and additional storage can increase total cost depending on organization needs.
Microsoft Teams is used for internal and external communication, hybrid meetings, remote collaboration and replacing or augmenting traditional phone systems. Organizations use Teams to centralize project conversations and files into channel spaces so cross-functional teams have a single contextual place for collaboration. Meetings scheduled through Teams or Outlook join directly in Teams with built-in screen sharing and recording, which reduces friction for both internal and external participants.
Teams is also used as a platform for integrating other business systems into conversational workflows: notifications from CI/CD systems, CRM alerts, ticket updates and document approval flows can be surfaced in channels and acted upon directly. Education customers use Teams for class collaboration, assignment management and virtual classrooms via integrated Teams for Education features.
From a telephony and contact center perspective, Teams can be used as a phone system with PSTN connectivity, enabling desk phone replacements, call routing, auto attendants and voicemail under a consolidated communications policy. This makes it useful for organizations looking to simplify vendor sprawl by keeping messaging, meetings and calling in the Microsoft 365 ecosystem.
Operational teams also rely on Teams for incident response and on-call coordination because it allows rapid group chat, file sharing and threaded discussion along with integrations to monitoring and alerting tools for immediate context.
Microsoft Teams offers a rich feature set and deep integration with Microsoft 365, which is an advantage for organizations already invested in the Microsoft ecosystem. Co-authoring Office documents inline, Teams meeting recordings saved to OneDrive/SharePoint, and centralized identity through Azure Active Directory simplify administration and user experience. For large enterprises, the advanced compliance, DLP, eDiscovery and information protection features available in higher-tier Microsoft 365 plans are major benefits.
Teams delivers robust meeting and calling features — background blur, large gallery, live captions, and meeting recordings — and can scale to large company-wide meetings with view-only broadcast modes. The Microsoft Teams developer platform and Microsoft Graph provide extensive extension points for bots, tabs and automation that are useful for internal tools and workflows.
On the downside, Teams can be resource intensive on client machines and mobile devices, and some users report a steep learning curve because it consolidates many different capabilities in one product. Organizations that are not already on Microsoft 365 may face migration effort and licensing complexity when choosing Teams, because the best administrative and compliance features require higher-tier Microsoft 365 plans.
Teams' interface and notification model can also be noisy for users if channel governance and notification settings are not carefully managed. Finally, while integration with third-party apps is strong, some niche or legacy systems require custom development work to integrate equivalently to native Microsoft 365 services.
Microsoft offers a free tier of Teams alongside trial periods for Microsoft 365 subscriptions that include Teams. The free tier provides basic chat, conferencing, file sharing and limited storage, which is often sufficient for small teams and pilot projects. For organizations evaluating paid Microsoft 365 plans, Microsoft provides time-limited trials of Business Basic or Business Standard that unlock features such as Exchange email, additional storage and desktop Office apps.
Trials of Microsoft 365 business plans typically run 1 month and can be initiated from the Microsoft 365 purchase pages; these trials allow administrators to test security, compliance and management capabilities such as conditional access and device management. Trials also give IT teams an opportunity to pilot Teams telephony add-ons and audio conferencing.
Because some advanced features (for example, phone system licensing, Advanced eDiscovery, or certain compliance controls) require additional licensing, it’s important to plan trial scenarios to cover telephony or compliance features you intend to evaluate. Check Microsoft Teams' current trial and evaluation options at Microsoft's subscription and trial pages: https://www.microsoft.com/en/microsoft-teams/compare-microsoft-teams.
Yes, Microsoft Teams offers a free plan that includes unlimited chat, built-in online meetings, 2 GB per user and 10 GB of shared storage, and access to web versions of Office apps. The free plan excludes advanced admin controls, PSTN calling, and some compliance features found in paid Microsoft 365 plans. Organizations can start with the free plan for small teams and upgrade to paid Microsoft 365 subscriptions when they need larger storage, email integration, desktop Office apps or enterprise-class security.
Microsoft Teams exposes programmatic capabilities primarily through Microsoft Graph and the Microsoft Teams developer platform. The Graph API surfaces REST endpoints for creating and managing teams, channels, messages, meetings, online presence, calls and recordings. Developers can use both delegated and application permissions, set up webhooks for message and channel change notifications, and manage Teams lifecycle and membership programmatically.
The Microsoft Teams developer platform supports building bots (via the Microsoft Bot Framework), custom tabs (web content embedded in Teams), message extensions, adaptive cards and apps that show up inside the Teams app store. Power Platform integration (Power Automate flows, Power Apps) allows citizen developers to automate workflows and build lightweight apps without full-stack development.
Supported SDKs include Microsoft Graph SDKs for multiple languages and Teams client SDKs for JavaScript and mobile platforms. Authentication uses Azure Active Directory with OAuth2, and permissions must be consented by administrators for tenant-wide app usage. For telephony and PSTN integration, the Cloud Communications APIs in Graph provide call control, participant management and media session capabilities for advanced voice scenarios.
Detailed developer documentation, API reference, SDK downloads and sample code are available on the Microsoft Teams developer platform and Microsoft Graph documentation sites: https://learn.microsoft.com/en-us/microsoftteams/platform and https://learn.microsoft.com/en-us/graph/teams-concept-overview.
