Microsoft Teams
Microsoft Teams is a Microsoft communication and collaboration app for chat, meetings, calls, and shared work across organizations and devices.
What is Microsoft Teams?
Microsoft Teams is a desktop collaboration app published by Microsoft Corporation. It is used for workplace messaging, online meetings, voice and video calls, team channels, and file collaboration, and it is commonly deployed with Microsoft 365 in business, education, and organizational environments. On macOS, the current app is associated with the bundle ID com.microsoft.teams2 and is typically installed as Microsoft Teams.app. Teams integrates with Microsoft 365 services such as Outlook, OneDrive, and shared Office documents so users can schedule meetings, join calls, and co-edit files from a single workspace. Many people encounter it as a required work or school communication tool, but it can also be installed directly from Microsoft's Teams download page. Depending on account type and admin policy, it may support organizational sign-in, guest access, notifications, screen sharing, and calendar-based meeting workflows.

Safety overview
Status: Safe
This is a legitimate Microsoft application. It is generally safe when obtained from Microsoft's official download or managed Microsoft 365 deployment tools. It may store sign-in tokens, chat-related data, logs, cached files, and organization account information locally, so shared or managed Macs can contain sensitive workplace data.
Recommendation: Keep it if you use Teams for work, school, or organization-managed communication. If you no longer use it, removal is usually optional, but check whether your employer or school expects it for meetings, chat, or account-based collaboration before uninstalling.
