Overview of Loop workspaces storage and permissions
Where the loop content was originally created determines its storage location. See the Loop Storage section in Summary of governance, lifecycle and compliance capabilities for Loop for a diagram and more information.
Loop app's usage of organization's storage quota
Loop app workspaces are stored inside your tenant. Loop workspaces and pages count against your tenant's storage quota, starting November 2023. (Note that during the Loop app's Public Preview in 2023, Loop app content did not use your existing storage quota.)
Content permissions mechanism
Each Loop app workspace uses storage for the workspace in SharePoint Embedded. Additionally, the Loop app creates a roster for that workspace to govern access to the full workspace. When pages are shared from the workspace, we create a sharing link using your company's default sharing link type as configured for OneDrive and SharePoint.
Sharing the workspace in Loop adds the user to the workspace roster. All workspace roster members have access and "editing" permissions to all the Loop pages in that workspace.
There's a distinction between sharing a specific Loop page with a user versus inviting them to a Workspace.
When you invite a user to a workspace, that user has access to all the pages in that workspace. Loop only supports inviting users to a workspace via this Workspace roster management flow, which enables access and sends an email invite to the invited users.
When you share only a Loop page, you're giving users access to that specific page exclusively (not the whole workspace). The user can choose to use a company share link or people-specific share link; unless their tenant admin has disabled some of the share link types. When sharing a page, you can choose to grant the user "edit" or "read only" access.
Loop workspaces and Microsoft 365 groups
Loop workspaces don't use Microsoft 365 groups for access management, instead they create a roster for access management.
eDiscovery support for Loop content stored in Loop workspaces
Loop content (pages and components) created in the Loop app are discoverable and have eDiscovery workflow support using the Microsoft Purview tool. As mentioned above, these files are stored in SharePoint Embedded and are available for search and collection for both eDiscovery (Standard) and eDiscovery (Premium). Render in review and the HTML offline export format is supported on eDiscovery (Premium). You can also download and re-upload the files to any OneDrive to view them in their native format.
A graph export API that can access Loop content stored in SharePoint Embedded is not yet available.
Storage management after user departure
In the Loop app
The Loop app is designed for shared workspaces and personal workspaces.
Shared workspaces are backed by a roster and continue to exist even if someone leaves the company. However, if the creator of the workspace is the person who left the company, then others can't delete the workspace.
Personal workspaces are also backed by a roster, but there's only one person in them by design. When a user leaves a company, their personal workspaces become ownerless.
In Loop components created in Microsoft 365 outside of the Loop app
Loop components created outside of the Loop are stored in the OneDrive of the person who created the component. Therefore, if that user leaves the organization, the standard OneDrive IT policy is applied.
