Office 365 – SharePoint Online: Site collection Administrators for beginners

Hi All,

In this article we will discuss about site collection administrators in SharePoint online site.

Site collection administrators are the users who have permissions over all content in Site Collection. These users have permission to all subsites as well in the Site Collection.

A site collection have only one primary administrator. Site collection can have multiple site collection administrators.

Difference between primary site collection administrator and other site collection administrators is, Primary site collection administrator receives administrative email alerts for the Site Collection. Also we can not specify “Security groups” for Primary Site Collection Administrator.

Site collection administrators doesn’t have the permissions on “SharePoint Admin Center” site unless and until specified.

Few Points:

1. SharePoint Online Administrator is administrator for SharePoint Online Administrator Center. SharePoint Online Administrator can create and manage site collections, designate site collection administrators, determine tenant settings etc.
2. Global Administrators is SharePoint Online Administrator.
3. “Site Owner” group gives the “Full Control” permission to individual site.  It allows to all the CRUD operations over the list and libraries, giving permissions to other users, creating new subsites and so on. These users are responsible for respective sites, they can’t change site collection level settings.

1. Sign in to Office 365 Admin Center (https://portal.office.com/adminportal/home#/homepage ) as
