The administrator for the Office 365 tenant can access the Azure portal to manage permissions and configure other settings.

Office 365 is a tenant in Azure Active Directory and uses the portal to store data used for authentication and to configure permissions for access to the Microsoft cloud environment. This blog post covers Office 365 AD sync and explains how you can perform Office 365 Active Directory sync to synchronize on-premises and cloud user accounts for Microsoft products.

This is known as a hybrid deployment, and it is popular among organizations using Microsoft software products. Administrators can synchronize the users of a local domain on-premises with Office 365 and Azure Active Directory (Azure AD) so as to use the same user account for both local and cloud authentication. Sometimes organizations prefer to use the same credentials for local user accounts and cloud user accounts. In this case, a system administrator has to create accounts for users in Microsoft 365. Many companies already using Windows have moved to a Microsoft cloud platform such as Microsoft 365 (previously Office 365) or Azure. Configuring an Active Directory Domain Controller (ADDC) on Windows Server is convenient, and admins can use this server to authenticate users, configure permissions, and manage access to shared resources. Organizations use Active Directory to centrally manage Windows computers and users. By Michael Bose A Step-by-Step Guide to Setting Up Office 365 AD Sync
