# Registering the OneDrive for Business Application

You must register the OneDrive for Business application with Azure Active Directory (Azure AD). Azure AD manages the connection between the OneDrive for Business application and the Commvault software.

Important

To complete this procedure, you must have a thorough understanding of Azure Active Directory. Consult Microsoft documentation, such as "Azure Active Directory Documentation" (https://docs.microsoft.com/en-us/azure/active-directory/).
