Microsoft SharePoint replaced the Wiki as our cloud-based document management and team collaboration software.
SharePoint uses document libraries, lists, and sites to organize and share content. In SharePoint, you can create document libraries to organize and share files and set permissions to control who can access, edit, or manage them.
In the upper left corner of the window, select the app launcher > All apps > SharePoint.
Tip: If you don't see the SharePoint app under All apps, use the Search box near the top of the window to search for SharePoint.
