Upgraded call history in Teams Calls app

🚨 The Signal: Teams call history expands to 3,000 records or six months, consolidating missed calls and voicemails. This change increases data retention, potentially impacting data discovery and e-discovery processes.

The Impact

All Teams users are affected by increased call history retention, posing a minor risk to data governance and e-discovery compliance.

• End users: Easier access to historical call data, potentially increasing data exposure.
• Security teams: Need to review data retention policies for Teams call history.
• Legal/Compliance teams: Expanded call history impacts e-discovery scope and data disposal.
• Admins: No direct action, but awareness of increased data footprint is required.

The Action

1. Review existing data retention policies for Microsoft Teams call data within Microsoft Purview.
2. Communicate the expanded call history retention to legal and compliance teams.
3. Update internal documentation regarding Teams data retention and e-discovery procedures.
