A Microsoft Teams license grants users access to Microsoft's collaboration and communication platform, enabling features such as chat, video conferencing, file sharing, and integration with other Microsoft 365 applications like Word, Excel, and PowerPoint. Depending on the specific license tier (e.g., Teams Free, Teams Essentials, Microsoft 365 Business Basic, Microsoft 365 Business Standard, or Office 365 E3/E5), users gain additional functionality such as larger meeting capacities, advanced security features, unlimited cloud storage, and integrations with third-party applications. The license also dictates the number of users allowed, the availability of enterprise-level management and administrative controls, and the level of customer support provided by Microsoft.
