Microsoft 365 Administrator Expert MS-102 Practice Question

You create a new Microsoft Purview data loss prevention (DLP) policy to prevent the sharing of credit card information in Microsoft Teams. During the Choose locations step of the wizard you select only Teams chat and channel messages. You then try to clear the Exchange email checkbox, but the interface prevents you from doing so. What is the most likely reason Exchange Online must remain selected in this scenario?

  • Teams chat and channel messages are stored in the participants' and team group Exchange Online mailboxes, so the policy must also inspect Exchange email.

  • Microsoft Purview DLP allows only one workload location per policy, so Exchange is automatically selected to satisfy this technical limitation.

  • Teams messages are journaled to Azure Communication Services, and Exchange is added only as a visual placeholder that cannot be removed.

  • Removing Exchange would disable auto-labeling capabilities for Office desktop apps, which are mandatory whenever Teams is chosen.
