Set the default OneDrive storage space in the SharePoint admin center

This storage space setting applies to all new and existing users who are licensed for a qualifying plan and for whom you haven't set specific storage limits. (To check if a user has a specific storage limit, see the next section.) To change the storage space for specific users, see Change a specific user's OneDrive storage space.

Note: If you decrease the storage limit and a user is over the new limit, their OneDrive will become read-only.
