Assign admin roles in Office 365

As the person who purchased your Office 365 subscription, you are the global administrator. This means you have complete control over the Office 365 suite of products. To help you manage Office 365 for your business, you can assign users to administrator roles so they can perform tasks in the Office 365 admin center. For example, if you want help resetting passwords, you can assign someone to the Password administrator role.

For a list of available admin roles that you can assign, and what they can do in Office 365, see About Office 365 admin roles.
