File name ABC.pdf is invalid – error while creating attachment programmatically

The other day I was getting “Invalid file name” error when I try to create an attachment with .pdf file and associating to Email, in my plug-in. (link)


  • Reason was “pdf” was added as blocked file extension for attachments in my CRM organization.

Fix :-

  • Go to “Settings -> Administration -> System Settings”
  • Remove pdf from “Blocked file extension for attachment”
Blocked file extensions

Blocked file extensions

  • Click ‘OK’
