Attachment Not Attached to Target Record due to Reason "found duplicate attachment by hash"SummaryBy default if you send a file as an attachment on an email, and that exact same file is already present as an attachment on the target record (e.g incident, case etc) the Inbound Email Action processing code will not move the attachment to the target record. The reason you'll see on the 'Email Attachments' tab on the Email[sys_email] record is "found duplicate attachment by hash".ReleaseAll Current ServiceNow releasesInstructionsYou can change this behaviour, so that the attachment is moved over to the target record despite being an exact match for an already existing attachment, by creating and setting the System Property glide.email.inbound.ignore_duplicate_attachments_by_hash to false (by default it is true)
