Microsoft Teams is Microsoft Corporation's (NASDAQ: MSFT) collaboration and communication app, spanning a consumer offering and an enterprise offering bundled into Microsoft 365/Office 365. Microsoft's own privacy statement discloses that Teams collects usage data and communication metadata (time, date, and participants of communications) as part of providing its features, syncs device/Outlook contacts with consent, and shares profile information with enterprise customers when a user interacts with their school or work accounts; it also discloses that third-party device notification services receive message-preview content to deliver push notifications and are governed by their own privacy policies, not Microsoft's. Apple's App Store privacy label discloses a broad 'Data Linked to You' bucket (location, contacts, user content, identifiers, usage data, diagnostics) used for Analytics and App Functionality purposes, but does not disclose the 'Data Used to Track You' cross-app tracking bucket that Microsoft self-declares for some other Microsoft apps. Microsoft's own developer documentation lists required, non-optional diagnostic telemetry events sent by the Teams desktop client. Ownership is fully traceable through Microsoft's SEC filings as a public company. No privacy-specific regulator order, breach notice, or fine naming Microsoft Teams was found; the European Commission did accept legally binding commitments from Microsoft in September 2025 over antitrust concerns about tying Teams to Office/Microsoft 365, but that case concerns competition law (bundling), not personal-data handling, so it is noted for context rather than used as privacy track-record evidence.
TRACK RECORD
1 ENFORCEMENT ACTION
[2025-09-12]
The European Commission announced on 12 September 2025 that it accepted legally binding commitments from Microsoft to resolve an antitrust investigation into tying Microsoft Teams to the Office 365 and Microsoft 365 productivity suites, requiring Microsoft to offer Teams-free suite versions at a reduced price, allow license switching, provide interoperability with competing tools, and allow customers to export their data out of Teams; this is a competition-law (bundling) enforcement action, not a data-privacy finding, so it is reported for context rather than counted as a privacy incident.
Microsoft's privacy statement states that Teams is an all-in-one collaboration and communication hub, and that as part of providing Teams features, Microsoft collects usage data as well as information about users' communications, including the time and date of the communication and the users who are part of it; the same section describes syncing device and Outlook contacts with permission and including user profiles in Teams public search directories.
Apple's App Store privacy label for Microsoft Teams (developer/seller: Microsoft Corporation) discloses a 'Data Linked to You' category listing location, contact info, contacts, user content, identifiers, usage data, and diagnostics as data that may be collected and linked to the user's identity.
Microsoft Corporation's FY2025 Form 10-K, filed with the SEC (Commission File Number 001-37845), identifies the company as incorporated in Washington and headquartered at One Microsoft Way, Redmond, WA, with common stock registered under the trading symbol MSFT on the Nasdaq exchange.
Microsoft's privacy statement states that when a user interacts through Teams meetings and chats with end users who are using a school or work account, Microsoft may share the user's profile information with the enterprise customer operating that school or work account; the same privacy statement separately discloses that Teams routes call/chat/message push notifications through the device's own third-party notification service, which receives content needed to display the notification (such as caller identity or the first words of a chat) and is governed by its own terms and privacy policy rather than Microsoft's, with Microsoft stating it 'is not responsible for the data collected by the company providing the notification service.'

Apple's App Store privacy label for Microsoft Teams discloses that data linked to identity -- including Location, Identifiers, User ID, Device ID, Usage Data, and Diagnostics -- may be used for 'Analytics' and 'App Functionality' purposes; the label does not carry a 'Data Used to Track You' cross-app tracking category (unlike Microsoft Copilot's App Store card).
Microsoft's developer documentation for the Teams desktop client lists required diagnostic events and the properties each event collects, describing this as data sent to Microsoft that is not fully optional (a Diagnostic Data Viewer is offered to inspect, not to disable, this required telemetry).
