Microsoft Teams: Upgraded call history in Teams Calls app

🚨 The Signal: Teams call history expands from 100 to 3,000 records or 6 months. This change increases data retention for call metadata, potentially impacting discovery and compliance requirements.

The Impact

This change affects all Teams users by increasing call history retention, which could impact data discovery and compliance.

• Security Teams: Increased data volume for eDiscovery requests.
• Compliance Officers: Review existing data retention policies for Teams call metadata.
• Legal Teams: Potential for more data to be discoverable in legal holds.

The Action

1. Review Microsoft Purview retention policies for Teams communications to ensure alignment with increased call history retention.
2. Communicate the change in call history retention to legal and compliance teams.
3. Assess eDiscovery workflows for potential impact due to larger data sets.
