Summary
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. Organizations should prepare by reviewing and updating policies.
Details
Introduction
We are introducing Microsoft Purview Data Lifecycle Management (DLM) retention support for Microsoft Teams call logs. Microsoft Teams stores call logs in several persistent locations, such as Call Detail Record (CDR) logs, which are currently retained indefinitely. However, regulatory requirements in various countries specify maximum retention periods for calling-related logs, creating a potential compliance gap. This update enables organizations to manage retention or deletion of Teams call logs to meet regulatory obligations, while still supporting evolving product features and business needs.
This message is associated with Microsoft 365 Roadmap ID 559261.
