Removing A User/Users From All Sharepoint Groups In A Site Collection

In this blog, I would like to explain how to remove a user/users from all SharePoint Groups. Removing a user/users from all SharePoint Groups in a Site Collection would be a complex task to do manually.

This will remove the selected user/users from all SharePoint groups, libraries, lists and sub sites in the Site Collection.

 

Step 1: Open Powershell Window in your environment.

Step2: Copy and paste the code, given below. Run the code. 

$LoginName = "domain\loginname"
$siteURL = "http://gowtham.sharepoint.com" #.

Clear-Host
$siteCount = 0
[system.reflection.assembly]::loadwithpartialname("Microsoft.SharePoint")
$site = new-object microsoft.sharepoint.spsite($siteURL)
$webApp = $site.webapplication
$allSites = $webApp.sites
foreach ($site in $allSites)
{

    $web = $site.openweb()
    $web.SiteUsers.Remove($LoginName)
    $web.Dispose()
    $siteCount++
}
$site.dispose()
write-host "User Deleed" $siteCount "Site Collections."
