Microsoft Imposes 1-Year Retention for Teams Meeting Attendance Reports

Microsoft has enabled a one-year retention policy for Teams meeting attendance reports. Tenants can’t opt out of the policy or set a different retention period. Microsoft says that the new policy exists to make sure that Teams complies with the Microsoft privacy policy. Another way of looking at the situation is that the new policy will simply remove some old data that no one ever looks at.
