Recently I came across a requirement to change the SharePoint Group owner, I googled for a while but could not find one which worked, at the end I wrote my own and I am sharing the same to help someone who might be in need of it.( tested and working :) )
Script Inputs:
$groupNameWildcard = "Owner" ( Name of the group: In this case all "Site name Owners" groups on all sites + subsites) This will specify which group owner you want to change, it is a wildcard which will check if the group name contains the said text.$newOwner = "Account" (New Owner account e.g. "domain\user")
$webApplicationURL = "Web App URL" (URL of the Web App where you want to change the owner for group on all site collections and subsites
The Script:
----------------------------------------------------------------------------------------------------------$groupNameWildcard = "Owner"
$newOwner = "Account Name"
$webApplicationURL = "Web App URL"
$webApp = Get-SPWebApplication $webApplicationURL
if($webApp -ne $null)
{
Write-Host "Web Application : " + $webApp.Name
foreach($siteColl in $webApp.Sites)
{
if($siteColl -ne $null)
{
Write-Host "Site Collection : " + $siteColl.Url
$siteURL = $siteColl.Url
#Get Site Collection
$site = Get-SPSite $siteURL
#Step through each site in the site collection
$site | Get-SPWeb -limit all | ForEach-Object {
if ($_.HasUniqueRoleAssignments) {
$spGroups = $_.get_Groups().web.Groups
$user = $_.EnsureUser($newOwner)
foreach($spGroup in $spGroups)
{
if ($spGroup.Name.Contains($groupNameWildcard))
{write-host "--------------------"
Write-host "Group Name:"$spGroup.Name
Write-host "Current Owner:"$spGroup.Owner
write-host "Updating Site" $_.Url
$spGroup.Owner = $user
$spGroup.Update();
Write-host "New Owner:"$spGroup.Owner
write-host "--------------------"
}
}
$_.Update();
}
else {
write-host "Site" $_.Url "will not be modified as it inherits permissions from a parent site."
}
}
#Display completion message and dispose of site object
write-host "Operation Complete."
$site.Dispose()
}
}
}
-----------------------------------------------------------------------------------
Happy Scripting :)
