Getting Started with Sharepoint Online
Get started with SharePoint Online
When you sign in to Office 365, or your organisation’s SharePoint site, click SharePoint in the app launcher navigation or top bar. These are your entry points into SharePoint.
What's in a SharePoint site
Organisations use SharePoint to create websites. In Office 365, you can create a site from the SharePoint start page. You also get a SharePoint team site whenever you create an Office 365 group in Outlook Online or Office 365. If you're in SharePoint Server, you can create a team or a number of other types of sites. You can use the sites as a secure place to store, organize, share, and access information from any device. All you need is a web browser, such as Microsoft Edge, Internet Explorer, Google Chrome, or Mozilla Firefox. Get the SharePoint mobile app to stay connected from your mobile devices.
