I'm looking for a Powershell to remove account from Additional admins on all SharePoint sites.

Anyone have the powershell script to do that?

    elaheh : Yes you can do that using PowerShell

    1) First, connection to the SharePoint using Connect-SPO service.

    2) Get handle of all site collections using GetSPOSite.

    3) Loop through each site

    4) Get all site collection admins using method Get-SPOUser   and IsSiteAdmin = true.

    5) Loop through each admin. (This will give you all the admins name).

    6) Inside this loop, add If condition for the admin whom you don't want to remove.

    7) And in Else condition write method for to remove. here you have to set IsSiteCollectionAdmin == False.

     

    I did this code long time back, it will be somewhere in the archival, need to check for the code.

     

    By that time, please check if you can achieve this through above guidelines.

     

    Hope this helps !

        elaheh : Below is the code( not exactly similar to what I wrote but you can refer and manipulate as per your need)

         

         

        Spoiler

        Import-Module Microsoft.Online.Sharepoint.PowerShell -DisableNameChecking
        #Variables for processing
        $AdminURL = "https://<SharePointTenantName>-admin.sharepoint.com/"
        $AdminAccount="adminAccount@email.com"

        #Connect to SharePoint Online
        Connect-SPOService -url $AdminURL -credential (Get-Credential)

        #Get All Site Collections
        $Sites = Get-SPOSite -Limit ALL

        #Loop through each site and add site collection admin
        Foreach ($Site in $Sites)
        {
        Write-host "Scanning site:"$Site.Url -f Yellow
        #Get All Site Collection Administrators
        $Admins = Get-SPOUser -Site $site.Url | Where {$_.IsSiteAdmin -eq $true}

        #Iterate through each admin
        Foreach($Admin in $Admins)
        {
        #Check if the Admin Name matches
        If($Admin.LoginName -eq $AdminAccount)
        {
        #Remove Site collection Administrator
        Write-host "Removing Site Collection Admin from:"$Site.URL -f Green
        Set-SPOUser -site $Site -LoginName $AdminAccount -IsSiteCollectionAdmin $False
        }
        }
        }

         

         

        Hope It helps !
