In early December, we identified a problem where the asynchronous deletion of folders in SharePoint Embedded   was not being invoked, causing deletion failures. This fix is now being deployed, and we want you to be aware of the current state and upcoming resolution.<\/p>\n<p>Tenant-owned <b>Loop workspace SharePoint Embedded (SPE) <\/b>containers may also experience these deletion failures. These issues will not be resolved with the initial fix rollout. However, you can mitigate them by excluding the affected containers from   Microsoft Purview retention policies, as described in the steps below.<\/p>\n<p><b>When this will happen:<\/b><\/p>\n<p>
