I am trying to create a new SharePoint site and then add an AD security group as an additional site collection admin to that newly created site.

The only way I found to make this work is to use import-csv to create the new site and then use set-spouser with the AD group (from a variable that is really the GUID of the AD security group). The first time I run the script below, the line with set-spouser gives me an error of "Set-SPOUser : File Not Found.".

What is strange is when I run the script again on the same .csv file to create new sites, it of course skips the new-sposite line because that site was already created the first time - but - it actually adds the AD security group as a site collection admin without any errors or issues.

Anyone have an idea of why I can't do this with one script execution?

#Change to your tenant
$adminUrl = "https://MYDOMAIN-admin.sharepoint.com"
$userName = "[email protected]"
# Let the user fill in their password in the PowerShell window
$password = Read-Host "Please enter the password for $($userName)" -AsSecureString
$ADGroupID = "6b6cbb5e-81bb-4e72-b806-709168823c20"
$LoginName = "c:0t`.c`|tenant`|$ADGroupID"
# Set credentials
$credentials = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $userName, $password
# Connect to to Office 365
Connect-SPOService -Url $adminUrl -Credential $credentials
write-host "Info: Connected succesfully to Office 365" -foregroundcolor green
write-host "Error: Could not connect to Office 365" -foregroundcolor red
Break new-SPOnlineSite

Import-Csv "C:\MyNewSiteCollections.csv" | ForEach-Object {
    New-SPOSite -Owner $_.Owner -StorageQuota $_.StorageQuota -Url $_.Url -NoWait -Template $_.Template -TimeZoneID $_.TimeZoneID -Title $_.Name 
    Set-SPOUser -site $_.Url -LoginName $LoginName -IsSiteCollectionAdmin $True
  • Maybe it is taking some time to create a site. Try removing -NoWait parameter from New-SPOSite OR try to get the site before Set-SPOUser using Get-SPOSite. Let me know if this works. Commented Sep 20, 2022 at 5:10

I think you are trying to add site collection administrator before new site is created in your tenant.

Try removing -NoWait parameter from New-SPOSite command like:

Import-Csv "C:\MyNewSiteCollections.csv" | ForEach-Object {
    New-SPOSite -Owner $_.Owner -StorageQuota $_.StorageQuota -Url $_.Url -Template $_.Template -TimeZoneID $_.TimeZoneID -Title $_.Name 
    Set-SPOUser -site $_.Url -LoginName $LoginName -IsSiteCollectionAdmin $True

Documentation: New-SPOSite

OR try to get the newly created site before using Set-SPOUser command. You can use Get-SPOSite command to get the site.

Use Set-SPOUser command only when you get the site instance correctly using Get-SPOSite command.

    I used Start-Sleep -Seconds 5 instead on a different line, but you had the right idea about needing to wait. Thanks! Commented Oct 17, 2022 at 1:51

To add a new membership group in Active Directory

Open the Active Directory Users and Computers console.

In the navigation pane, select the container in which you want to store your group. This is typically the Users container under the domain.

Click Action, click New, and then click Group.

In the Group name text box, type the name for your new group.

In the Description text box, enter a description of the purpose of this group.

In the Group scope section, select either Global or Universal, depending on your Active Directory forest structure. If your group must include computers from multiple domains, then select Universal. If all of the members are from the same domain, then select Global.

In the Group type section, click Security.

Click OK to save your group.
