Microsoft Purview DLP now supports adaptive scopes for SharePoint Online sites, allowing administrators to dynamically target DLP policies based on site attributes instead of manually selecting individual sites. Rolling out from late January through late February 2026.
Rollout: Late January to late February 2026
What it does: Automatically includes/excludes SharePoint sites in DLP policies based on rules
Targeting criteria: Site URL, site name, or custom SharePoint managed properties (RefinableString00-99)
Key benefit: Removes the 100-site static policy limit
Query language: Keyword Query Language (KQL)
Limitation: Administrative units do not yet support SharePoint site scopes
Previously, DLP policies for SharePoint sites required manually adding each site, with a hard cap of 100 sites per policy. Adaptive scopes evaluate site properties continuously and auto-include or exclude sites as they change. This is especially useful for large tenants where sites are created frequently and manual policy maintenance is impractical. The feature uses the same KQL syntax familiar from SharePoint search, configured through custom managed properties.
