Microsoft SharePoint: The "spaces" feature will retire

Updated April 21, 2025: We will be rolling out the change to prevent users from activating the SharePoint spaces feature in site settings (or using PowerShell) starting May 15th. It will still be possible to disable the feature using this dialog. Users attempting to enable the feature will receive an error message indicating that the Spaces feature is being deprecated and cannot be enabled at this time. Sites with the feature already enabled will continue to function with the feature enabled. Due to limited usage and our focus on investing in Microsoft Mesh where immersive 3D content can be created and experienced in a multi-user collaborative experience, we will retire the spaces feature from Microsoft SharePoint Online starting March 10, 2025 and ending August 11, 2025. As another alternative, you may choose to transition some existing content to SharePoint Pages. How this will affect your organization: Users will no longer be able to view or create SharePoint spaces after this retirement is complete. Retirement timeline details: Starting March 10, 2025, the spaces feature be turned off by default. After this date, users can still access the spaces feature on SharePoint sites that have used it previously and users can enable the feature for individual sites on the Site features page. Starting May 15, 2025, users will no longer be able to enable the spaces feature on the Site features page, but SharePoint sites with the feature already enabled will continue to function as normal. Starting August 11, 2025, the feature will be fully disabled and users will be unable to view, edit, or create new spaces.
