SharePoint Online: Get the Site Owner using PowerShell

[michael1900]

Need powershell code to  Get the Site Owner using PowerShell .

I tried to using below code but the data is no accurate and no incorrect .

#Variables for Admin Center

$AdminCenterURL = https://89889-admin.sharepoint.com

$CSVPath = "c:/temp/danny.csv"

#Get Credentials to connect

$Cred = Get-Credential

#Connect to SharePoint Online and Azure AD

Connect-SPOService -url $AdminCenterURL -Credential $Cred

Connect-AzureAD -Credential $Cred | Out-Null

#Get all Site Collections

$Sites = Get-SPOSite -Limit ALL

$SiteOwners = @()

#Get Site Owners for each site collection

$Sites | ForEach-Object {

    If($_.Template -like 'GROUP*')

    {

        $Site = Get-SPOSite -Identity $_.URL

        #Get Group Owners

        $GroupOwners = (Get-AzureADGroupOwner -ObjectId $Site.GroupID | Select -ExpandProperty UserPrincipalName) -join "; "     

    }

    Else

    {

        $GroupOwners = $_.Owner

    }

    #Collect Data

    $SiteOwners += New-Object PSObject -Property @{

    'Site Title' = $_.Title

    'URL' = $_.Url

    'Owner(s)' = $GroupOwners

    }

}

#Get Site Owners

$SiteOwners

#Export Site Owners report to CSV

$SiteOwners | Export-CSV -path $CSVPath -NoTypeInformation -Encoding utf8 -Append

Need other code to help catch the sharepoint owner/site admin with accurate .

Hello @michael1900,

One of the options to get Site Admins is to get list of all members of the site and then identify who has IsSiteAdmin property equal to True:

$SiteAdmins = (Get-SPOUser -Site $URL -Limit ALL | Where-Object { $_.IsSiteAdmin -eq $True} 

Here is your code with the added line:

$AdminCenterURL = "https://<TenantName>-admin.sharepoint.com/"
$CSVPath = "c:/temp/danny.csv"
Connect-SPOService -url $AdminCenterURL
Connect-AzureAD
$Sites = Get-SPOSite -Limit ALL
$Results = New-Object 'System.Collections.Generic.List[psobject]'

forEach($s in $Sites) {
    If($_.Template -like 'GROUP*')
    {
        $GroupOwners = (Get-AzureADGroupOwner -ObjectId $s.GroupID | Select -ExpandProperty UserPrincipalName) -join "; "     

    }
    Else{
        $GroupOwners = $s.Owner
    }
    $SiteAdmins = (Get-SPOUser -Site $s.URL -Limit ALL | Where-Object { $_.IsSiteAdmin -eq $True} | Select-Object -ExpandProperty DisplayName) -join "; "
    $Results.Add( $(New-Object PSObject -Property $([ordered]@{
    'Site Title' = $s.Title
    'URL' = $s.Url
    'Owner(s)' = $GroupOwners
    'Admin(s)' = $SiteAdmins
    })))
}
$Results| Export-CSV -path $CSVPath -NoTypeInformation -Encoding utf8

Hope that helps.
