We are asked which Microsoft Teams activities can be protected by a DLP policy when applied to different resource scopes: user accounts, Microsoft 365 groups, and security groups or distribution lists.

Step 1 – How DLP applies in Teams

User accounts → Controls 1:1 or group chats (1:1/n chats).

Microsoft 365 groups → Controls Team channel messages (general and private channels).

Security groups or distribution lists → Used as a scoping mechanism for users, but only applies to 1:1/n chats, not to channel messages.

???? Reference: Learn about DLP in Microsoft Teams

Step 2 – Map activities

User accounts → Can protect 1:1/n chats only.

Microsoft 365 groups → Can protect Private channels only and General chats only (both types of Teams channels).
