What is OneDrive?

OneDrive is the Microsoft cloud service that connects you to all your files. It lets you store and protect your files, share them with others, and get to them from anywhere on all your devices. When you use OneDrive with an account provided by your company or school, it's sometimes called OneDrive for work or school.

If you’re using Microsoft 365, you get at least 1 TB of space in the cloud, depending on your plan. If your OneDrive library is hosted on a Microsoft SharePoint server in your organization, your organization’s administrators determine how much storage space is available.

All files that you store in OneDrive for work or school are private unless you decide to share them. You can share files and folders with co-workers so you can collaborate on projects. If you’re signed-in to Microsoft 365, you may even be able to share with partners outside of your organization, depending on what your company allows.

Tip: When you send email from Outlook Web App, you can attach a OneDrive file as a link, instead of sending an attachment. When you Attach a file as a link, you automatically give the people you send the message to permission to edit the file. Plus, you save space in everyone's mailbox and encourage people to edit the same copy in OneDrive.

To get to OneDrive:

  1. Sign in to Microsoft 365 or your SharePoint site with your work or school account.

  2. At the top of the page, select the app launcher The app launcher icon in Office 365 , and then select OneDrive.

OneDrive is part of your organization’s subscription to SharePoint in Microsoft 365 or through an on-premises installation of SharePoint Server.

To sync OneDrive with your local computer, you'll need the OneDrive sync app which lets you Sync files to your PC or Mac. This sync app is available with Office 2013, Office 2016, or with Microsoft 365 subscriptions that include Office 2016 applications. If you don’t have Office, a free download of the OneDrive sync app is also available.

It's all OneDrive, which means you use the same apps to sync files down to your Windows PC or Mac, or get to your files from your Android or iOS device. You just sign in with your work or school account to use, or sign in with your Microsoft account to use OneDrive personal.
