Microsoft 365 retention policies control how the system removes items automatically from Exchange Online, SharePoint Online, Teams, and other locations. Because these policies are so powerful, it’s a good idea to keep an eye on who makes changes to their settings. The audit log is a natural place to go looking for information about policy updates and while we can find information there, some of the data is oddly formatted or obscured for some reason. Persistence and PowerShell delivers answers, but this is a task way harder than it should be.
Office 365 tenants will soon be able to create adaptive scopes for retention policies. An adaptive scope is nothing more than a filter to select target mailboxes, sites, and Microsoft 365 groups based on some criteria. They’re adaptive because administrators don’t have to update policies as they add new objects. Like other Microsoft 365 Information Governance features which automate some aspect of operations, adaptive scopes are likely to demand Office 365 E5 or Microsoft 365 E5 Compliance licenses.
