We tried to delete a list in SharePoint suddenly we got an error message “The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator.
Using GUI we are unable to delete the list because of list view threshold for this using PowerShell we disable the list view threshold.
$web = Get-SPWeb http://dotnetsharepoint.com/sites/sharepoint
$list = $web.Lists["ListName"]
$list.EnableThrottling = $false
Now we can able to delete the list without any issues.
