Is there a way to add a security group as Primary or secondary site collection administrator to all the sites in the tenant via PowerShell?
I know this works for adding a user account to all the sites as SC Admin
$Sites = Get-SPOSite -Limit ALL
Foreach ($Site in $Sites)
Set-SPOUser -site $Site.Url -LoginName $AdminName -IsSiteCollectionAdmin $True
The same command with
Set-SPOSiteGroup does not work
Set-SPOSiteGroup : A parameter cannot be found that matches parameter name 'IsSiteCollectionAdmin'
Since 'IsSiteCollectionAdmin' is not accepted with
Any suggestions on how to set security group as site collection administrator via PS script/ cmdlets?
