Microsoft Office servers

SharePoint is a web-based collaborative platform primarily used for building corporate intranets, document and content management, and file sharing. Developed by Microsoft, it is primarily used as part of the hosted service Microsoft 365, but it can also be hosted by an IT department or service provider, using an on premises version called "Server Edition". Launched in 2001, it was initially bundled with Windows Server as Windows SharePoint Server, then renamed Microsoft Office SharePoint Server, and then finally renamed SharePoint.
