Dear @Glenn Maxwell,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, Microsoft Teams meeting recordings stored in SharePoint are being automatically moved to the SharePoint Recycle Bin by the SharePoint app, you wonder how can prevent this, and is it controlled by Teams or SharePoint deletion/retention policies.
Here are some information and suggestions you can refer to:
Microsoft Teams meeting recordings are moved to the SharePoint (or OneDrive) Recycle Bin as a result of the Teams meeting recording expiration policy, not because of any SharePoint deletion or retention policy.
Teams controls the lifecycle of meeting recordings by assigning an expiration date through Teams meeting recording policies. When a recording reaches its expiration date, Teams initiates the deletion. SharePoint (or OneDrive) only acts as the storage backend and executes the delete command issued by Teams, which is why the action appears in audit logs as “Deleted by SharePoint app.”
Because the deletion is initiated by Teams, it cannot be prevented using SharePoint deletion or retention policies alone. SharePoint does not independently decide to delete Teams recordings.
To prevent recordings from being removed, you must:
- Configure the Teams meeting recording expiration policy (for example, extend the expiration period or disable expiration)
- Apply a Microsoft Purview retention policy, which can override the deletion attempt and protect the recording from permanent deletion.
