You need to follow Public and private team activity official guide. 

Office 365 Securlet can track public and private team activity. Team activity violations appear as policy alerts in the Office 365 Securlet dashboard. A custom attribute can also be used in Symantec DLP policies to differentiate between public and private team activity.

To use the contextual attribute in a DLP policy, perform the following steps in Symantec DLP and Microsoft Office 365:

  1. Create a Symantec DLP policy and rule with the following options:
    - Attribute: string
    - Name:
    - Match: team_type In the preceding option, team_type is Public or Private.
    - Match type: Match exactly
  2. Create a team in Office 365.
