Scope of DLP protectionĭLP protection is applied differently to Teams entities. Any sensitive information present in the part of the message that appears in the preview will remain visible in the notification even after the DLP policy has been applied and removed sensitive information the message itself. Activity notifications-which include a short message preview and appear based on a user's notification settings-are not included in Teams DLP. To learn more about licensing requirements, see Microsoft 365 Tenant-Level Services Licensing Guidance.ĭLP applies only to the actual messages in the chat or channel thread. Support for DLP protection in Teams Chat requires E5. This also includes files that are shared through Teams because Teams uses SharePoint Online and OneDrive to share files. Office 365 and Microsoft 365 E3 include DLP protection for SharePoint Online, OneDrive, and Exchange Online.

That another team may have a different DLP policy, but that doesn’t matter. Share with team (internally): You share the channel with another team TeamB in Contoso.Everyone in this shared channel, including user1, will be covered by P1. Share with member: You invite user1 from Contoso to join the shared channel without making him a member of TeamA.
For example let’s say there's a shared channel owned by TeamA of Contoso. For shared channels, the host Teams team DLP policy are applied. This is an example of DLP for SharePoint that shows up in Microsoft Teams, and therefore requires that users are licensed for Office 365 DLP (included in Office 365 E3), but does not require users to be licensed for Office 365 Advanced Compliance.)Įxample 3: Protecting communications in Teams Shared Channels. Your DLP policy must include SharePoint and OneDrive in order for protection to be in place. If you have a DLP policy defined to prevent this, the document won't open for those users. Suppose that someone attempts to share a document with guests in a Microsoft Teams channel or chat, and the document contains sensitive information.
