Tenants with Microsoft 365 Archive configured can incorporate an archiving step in how Purview retention policies and labels process SharePoint Online and OneDrive for Business files. It makes perfect sense to move inactive files to lower-cost archive storage as an intermediate point some time before their final deletion. You’ll save on storage and stop AI tools processing the digital debris that invariably accumulates in SharePoint.
Microsoft Purview is expanding its ability to process data from external services such as Google Workspace and Box through DLP policies and Information Protection auto-labeling. Everything depends on Microsoft Defender for Cloud Apps connectors to fetch data from the external services to Azure to be processed there. This is an esoteric play that will appeal to certain enterprise Microsoft 365 tenants with the need for a common protection strategy across multiple cloud platforms.
The Get-AdaptiveScopeMembers cmdlet reveals details of adaptive scope membership to make it possible to report this information programmatically. The task is not as simple as you might imagine. Summary records must be separated from member records, which can reflect add or remove operations. And there’s the question of pagination for large adaptive scope. All explained here with a PowerShell script to help.
During the quiet holiday period, I tested the new Purview Data Security Investigations (DSI) solution, which seems to be put together from bits of Microsoft 365 together with Security Copilot and some generative AI. Assembling new solutions from existing components makes sense because it reduces engineering effort. Without real data, it’s hard to know how effective DSI is, but the cost of an investigation came as a real surprise.
The Ignite 2025 keynote was a marathon 150-minute event, but some interesting Microsoft 365 announcements emerged, mostly centered on AI. Microsoft is obviously focused on making AI and agents a very real part of tenant activities, so there’s new agent management and a repository among other things that will roll out in the year ahead.
