powershell - How do I delete Version History files in SharePoint Online? -


i trying delete version history files in sharepoint online through powershell. research has provided plenty of examples on how in sharepoint 2010 , 2013 not sharepoint online. files reside in document libraries. script below seemed promising task have been unable modify work sharepoint online. changes necessary make work sharepoint online?

[void][system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint") # site $site = new-object microsoft.sharepoint.spsite("http://xxx.sharepoint.com") # loop through webs foreach ($web in $site.allwebs) {    write-host $web.url    # loop through lists in web    foreach ($list in $web.lists)    {       # examine if basetype of list not document library       if (($list.basetype -eq "documentlibrary") -and ($list.enableversioning))       {          # delete version history          foreach ($item in $list.items)          {            # work file object we're in document library            $file = $item.file            # delete versions            $file.versions.deleteall()          }       }    } } $web.dispose(); $site.dispose();

the code below combines powershell , csom. worked me. can delete versions or adjust versions deleted using counter in loop.

[system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint.client") [system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint.client.runtime")  $password = read-host -prompt "enter password" -assecurestring $credentials = new-object microsoft.sharepoint.client.sharepointonlinecredentials("userid@yourtenant.com", $password)  $siteurl = "https://yourtenant.sharepoint.com/sites/yoursitecollection" $context = new-object microsoft.sharepoint.client.clientcontext($siteurl) $context.credentials = $credentials   $fileurl = "/sites/yoursitecollection/path_to_file/filename"; $versions = $context.web.getfilebyserverrelativeurl($fileurl).versions;  $context.load($versions) $context.executequery()  for($i=2;$i -lt $versions.count-2; $i++)  {     $versions[$i].deleteobject()     $context.executequery() }
