SharePoint Online provides built-in ways to view team site content on any mobile device. You can use your mobile device to open documents, find sites, and navigate SharePoint Online. Each site has a pc view and a mobile view that you can switch back and forth.
Note: If your site admin does not enable this feature, you can only see a browser view. For more information, see Configure a SharePoint site for mobile devices.
Note: The following procedure works the same on all supported devices, although there may be some small differences in display and formatting.
Open the web browser on your device, and then in the address bar, type the website address (URL) for SharePoint Online, such as http://contoso.sharepoint.com.
Tip: Create a Favorite in your browser.
