Add a user as Admin to every new Site created for my Office 365 tenant

Question

I want to know if I can set some configuration which would automatically add a user I specify as Site Admin to any new Site created.

I know that it is possible for MY sites but I want to know if I can do that for sites which are of the type

• https://{tenantName}.sharepoint.com
• https://{tenantName}.sharepoint.com/teams
• https://{tenantName}.sharepoint.com/sites

Any help with this?

There isn't anything native to do this. We have it included as part of a provisioning commandlet that follows our business logic for quotas and architecture. You could do it like this using SharePoint Online PowerShell module to update existing sites, and just include the Set-SPOUser in your provisioning:

$sites = Get-SPOSite -limit all
foreach ($site in $sites){
    if ($site.Url -like "*/sites/*" -or $site.Url -like "*/teams/*" -or $site.Url -eq "https://yourtenant.sharepoint.com"){
        #$site.Url
        Set-SPOUser -Site $site -LoginName "[email protected]" -IsSiteCollectionAdmin
    }
}
