In our production environment we are using a Content Type Hub to publish CT's to multiple site collections. On one of the site collections the publish is failing, error log says “Field internal name 'Employee_x0020_Name' conflict“.
Typically deleting the "local copy" of the site column on the site collection would fix this issue, however when I trythe delete operation acts like it worked (no error messages, etc.), but the site columnEmployee Name still shows up in the list of local (site collection) site columns.
I have used SharePoint Managerto try and find instances of a content type using the Employee Name site column, hoping that deleting that content type would help to delete the column, however I can’t find any content types on the site collection using the Employee Name site column.
I’ve also tried to delete the site column using PowerShell. Same thing – says successful, but the site column is still there laughing at me.
I suspect this site column to be an artifact of a site migration from another server.
Suggestions please?
