admin roles in Office 365 Enterprise

There are five admin roles in Office 365 Enterprise :

1.Global admin
2.Billing admin
3.Password admin
4.Service admin
5.User management admin

 

 

 

Depending on the size of your organization, you may want to designate several admins who serve different functions. The following admin roles are available:

• Billing admin: Makes purchases, manages subscriptions, manages support tickets, and monitors service health.

 NOTE   If you didn’t purchase Office 365 from Microsoft, you can’t make billing changes and therefore can’t be assigned the billing admin role. For billing issues, contact the admin at the organization where you purchased your subscription.

• Global admin: Has access to all administrative features. Global admins are the only admins who can assign other admin roles. You can have more than one global admin in your organization. The person who signs up to purchase Office 365 becomes a global admin.

• Password admin: Resets passwords, manages service requests, and monitors service health. Password admins are limited to resetting passwords for users and other password admins.

• Service admin: Manages service requests and monitors service health.

 NOTE   Before global admins can assign the service admin role to a user, they first assign the user administrative permissions to a service, such as Exchange Online, and then assign the service admin role to the user in Office 365.

• User management admin: Resets passwords, monitors service health, and manages user accounts, user groups, and service requests. The user management admin can’t delete a global admin, create other admin roles, or reset passwords for billing, global, and service admins.
