MC235288 – Updated April 09, 2021: Microsoft has updated the rollout timeline below. Thank you for your patience.
SharePoint spaces allows the creation and sharing of immersive or browser-based mixed reality environments using assets such as 3D models, 360° images and videos, and 2D content such as videos, images, and office documents. In October 2020 (MC224942), SharePoint spaces became generally available.
Microsoft is now including spaces in the site level +New menu by default.
How this will affect your organization:
Users with appropriate permissions to create content on a site will see an additional entry for creating a Space in the +New menu on all SharePoint sites.
As with pages, SharePoint site owners will continue to have the option to turn off the spaces feature for their sites using the Manage Site Features page or using PowerShell cmdlets described below.
What you need to do to prepare
You should determine whether you want to maintain the current behavior (where site owners must enable SharePoint spaces at the site level before it will show in the +New menu) or have spaces show in the +New menu by default across your tenant.
In addition to the tenant level control, you can also use PowerShell to enable or disable the spaces entry in the +New menu for individual sites.
For both site-level commands, the variable $siteURL contains the URL to the specific SharePoint site where you want to enable or disable the +New menu entry.
