If you're working on a file by yourself, save it to OneDrive. Your OneDrive files are private unless you share them with others, which is particularly useful if you haven't created a team yet.
If you're already working as a team — in Microsoft Teams, SharePoint, or Outlook—you should save your files where your team works, because OneDrive for work connects you to all your shared libraries, too.
When you need a new shared location to store team files, create a shared library right from OneDrive, add members, and start working together. These libraries are accessible within Teams, SharePoint, and Outlook. And it's easy to copy or move files where you and others need them.
OneDrive is the files experience for Microsoft 365, giving you access to all your work files, including the files that people share with you directly or through the teams you're working on. OneDrive provides a consistent, intuitive files experience across all your devices, including web, mobile, and the desktop of your Windows PC or Mac.

SharePoint is always there, helping manage and protect your files, and powering content collaboration across Microsoft 365. And beyond files, SharePoint enables portals, news, pages, lists, and a platform for business apps.

There are a few issues to keep in mind when moving documents from OneDrive and a shared library:
