Microsoft Purview: Data Lifecycle Management – Retention support Microsoft Teams call logs

Microsoft Purview Data Lifecycle Management will support retention and deletion policies for Microsoft Teams call logs starting late April 2026. This enables compliance admins to manage call log retention per regulations, ending indefinite default retention, without affecting user calling experiences.
