Sticky problem here. All I've seen with Powershell is 2010 code, but I'm on the 365/Online version of Sharepoint.

I need to delete two site columns. I've removed them from everything I could imagine. Emptied both Recycling bins.

Still, all I get is this error:

Site columns which are included in content types cannot be deleted. Remove >all references to this site column prior to deleting it.

Thoughts? I either need to know where it is still sitting, or another way to remove.

Could you test with Powershell, e.g. https://gallery.technet.microsoft.com/Get-Content-Types-with-a-e67b46e6 ?

Do you have subsites/lists where the columns could have been added? I don't think the script above is recursive so you would need to adapt it, along the lines:

foreach($ll in $Lists){
foreach($cc in $ll.ContentTypes)

   $ErrorActionPreference= 'silentlycontinue'
     catch [Net.WebException]

    if($column.Title -eq $NameOrTitle.Trim())
      Write-Host $cc.Name
  • Hey, I deleted my only subsite. I've removed the column from all the Content Types that I could image. What do you mean by "recursive"? I'm being prompted for my password twice in above script and then it fails. Sep 14, 2015 at 12:29

  • Very interesting! Jo, where did you find the reference to this site column in your case? Some list still using it?
