Adding a new site collection admin to all SharePoint Online sites

Administration of sites requires having a certain level of access for a site collection. Users with the SharePoint Admin role have full control access to all sites, but there may be a reason to give a user without an Admin role elevated SharePoint access (for example, a site developer). This recipe explains how to give an admin access to all SharePoint Online sites. However, it can be amended to give such access to specific site collections, or a single site collection.

Getting ready

This recipe will utilize the skills learned in the Setting up the PowerShell environment recipe in Chapter 1, Office 365 Setup and Basic Administration, and the Connecting via PowerShell to SharePoint Online recipe in this chapter, and require that you are a global or SharePoint admin.

How to do it…

$Sites = Get-SPOSite -Limit ...
