Find your Office 365 tenant ID
Your Office 365 tenant ID is a globally unique identifier (GUID) that is different than your organization name or domain. You might need this identifier when you configure Group Policy objects for OneDrive.
To find your Office 365 tenant ID in the Azure AD admin center
Sign in to the Azure Active Directory admin center as a global or user management admin.
Under Manage, select Properties. The tenant ID is shown in the Directory ID box.
