Storage
Copilot Pages and Copilot Notebooks are stored within your organization in SharePoint Embedded. Each user has a single user-owned container that stores Copilot Pages, Copilot Notebooks, and Loop My workspace content. The container is lifetime managed with the user account and can be managed using SharePoint Embedded admin tools.
Container name
Copilot Pages, Copilot Notebooks, and Loop My workspace all use the same user-owned container. This container is named 'Pages' if the person visits the Microsoft 365 Copilot app first. It is named 'My workspace' (localized into the language of the user's Loop experience during creation) if the person visits the Loop app first. Refer to listing all user-owned containers to get a list, regardless of the container name.
This single user-owned container is created when a user first needs one of these experiences and at least one of the relevant creation policies allows it. If Create Loop workspaces in Loop is disabled but Create and view Copilot Pages and Copilot Notebooks is enabled, creating a Copilot Page or Notebook can still create the container. If Create and view Copilot Pages and Copilot Notebooks is disabled but Create Loop workspaces in Loop is enabled, opening Loop My workspace can still create that same container.
To prevent the single user-owned container from being created, disable both policies for the same user. In SharePoint admin center and PowerShell, the owning application for this container is shown as Loop.
Storage quota
All Copilot Pages and Copilot Notebooks count against your organization's SharePoint storage quota.
SharePoint Embedded also offers a platform for developers to build their own applications. This alternate usage pattern, which bills per use, is different from Loop and Copilot Pages storage quota management.
Storage limits
Copilot Pages + Copilot Notebooks container has a maximum size of 25 TB. This limit can't be increased or decreased. Learn more about SharePoint Embedded container limits.
Storage management after user departure
Copilot Pages and Copilot Notebooks are stored together in the same user-owned SharePoint Embedded container. This personal content is private by default, allowing users to work without forced sharing or coauthoring, similar to OneDrive.
Container lifecycle
- The container is lifecycle managed with the user account and is deleted when the user account is deleted from the organization.
- You can't permanently reassign content to a new owner.
- The container follows the same cleanup schedule as OneDrive: 30 days active, then soft deleted, and permanently purged 93 days after soft deletion.
- Admins can recover the entire container (including all Copilot Pages and Copilot Notebooks) during the soft delete period using the SharePoint Admin Center or PowerShell.
Note
When a user selects the Copilot Pages module in the Microsoft 365 Copilot app, a SharePoint Embedded container is currently created automatically—even if the user doesn't create a Copilot Page. If no files are added, the system deletes it automatically. This behavior is temporary. An update is in progress to ensure containers are only created when users actually create content. Until then, IT administrators can safely disregard these system-initiated deletions.
Important
A workflow for IT admins to assign temporary custodians during the cleanup period isn't yet available. This capability is planned (Microsoft Roadmap ID 421612).
Important
There's no end-user recycle bin for Copilot Notebooks. Neither administrators nor end users can recover individually deleted Copilot Notebooks.
