To create a keyword dictionary for a sensitive information type in Microsoft Purview Data Loss Prevention (DLP), you must use a plain text (.txt) file where each keyword is on a separate line.

Format Example (TXT file):

confidential

sensitive

classified

top secret

This format is simple, efficient, and directly compatible with Microsoft 365 DLP policies for keyword dictionaries.

How to use the keyword dictionary?

● Create a text file with one keyword per line.

● Upload it to Microsoft Purview under Data Classification > Sensitive Info Types.

● Use the dictionary in a DLP policy to identify and protect sensitive information.

An activity policy in Microsoft Defender for Cloud Apps (Microsoft Defender portal) allows you to track and alert on specific user actions, such as sharing sensitive documents externally from OneDrive.

The content search uses the KQL editor with the query -Author:USER1. In eDiscovery/Content search, the minus sign denotes NOT and KQL is case-insensitive for property values. Therefore, this query returns items whose Author is not ‘User1’.

File1.docx → Author = User1 → excluded

File2.docx → Author = User2 → included

File3.docx → Author = USER1 (same as User1, case-insensitive) → excluded

Result: File2.docx only.

To extend DLP to Teams, you must enable Teams chat and channel messages as a location in the DLP policy. SharePoint and OneDrive protect stored content, but chat sessions require the Teams-specific location.
