Your organization recently got Office 365, and now you need to use Office 365 so you can start reading email, sharing documents, and more.
Sign in to your new Office 365 account
Sign in to Office 365 with your work or school account. For example firstname.lastname@example.org. If you're not sure what your work account is, check the welcome email message that asked you to sign in the first time.
Use Office 365 on your phone or tablet
You can use Office 365 with many phones, tablets, and other mobile devices—including Windows Phones, iPhones, BlackBerry® devices, and Android devices. Depending on your mobile device, you can use email, share documents, and more.
Use Word, Excel, and other Office programs
Both SharePoint team sites and OneDrive for Business let you access and share documents, including documents from Word, Excel, PowerPoint, OneNote, and Access. Anyone can use Office Online, which include Word Online, Excel Online, PowerPoint Online, and OneNote Online. To make a new document, click OneDrive at the top of the page, and then click New document.
