Assign admin roles in Office 365

As Office 365 admin - the person who purchased your subscription - you are a global administrator and can do any task in the Office 365 suite of products. To help you administer Office 365, you can assign users to administrator roles so they can perform tasks in the Office 365 admin center that map to common business functions.

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.
