(Updated 27.1.2022)
Automatic expiration of Teams meeting recordings will be enabled between early January to mid-February 2022 timeframe, the exact timeline for a tenant will be informed on Microsoft 365 Admin Message Center.
By default, auto-expiration is set to 60 days. Recordings stored before the feature is effective are not affected in OneDrive, SharePoint, or in classic Stream. Administrators can control the default setting with PowerShell and in Teams Admin Center. The expiration setting can be from 1 day to 99,999 days (273 years) or set to never expire with value -1. Auto-expiration is not overriding compliance policies.
Currently never expire setting cannot be set on Teams Admin Center. When the auto-expiration setting is changed, the new setting is effective for recordings stored after the setting change. Controls for auto-expiration settings are now available, so you can start preparing for the change.
