With Office 365, you can delegate some administrative rights to your user.
When you want to do this, you have to know which administrative level to assign.
- Billing administrator: Makes purchases, manages subscriptions, manages support tickets, and monitors service health
- Global administrator: The top-level administrator in your company. When you sign up to purchase Office 365, you become a global administrator. Global administrators have access to all features in the administration center and only global administrators can assign other administrator roles. There can be more than one global administrator at your company
- Password administrator: Resets passwords, manages service requests, and monitors service health. Password administrators can reset passwords only for users and other password administrators
- Service administrator: Administers services, such as Microsoft Exchange Online, but does not require access to user management and other administrative functions. This role manages service requests and monitors service health
- User management administrator: Resets passwords, monitors service health, and manages user accounts, user groups, and service requests.
Some limitations apply to the permissions of a user management administrator. For example, they cannot delete a global administrator or create other administrators. Also, they cannot reset passwords for billing, global, and service administrators
To delegate administrative rights, open the Office 365 administration portal and go to Management\Users section.
Then click on the user account you wish to assign administrative rights and go to settings
You are also able to assign administrative right when creating a new Office 365 user from the portal
