I'm sending a attachment by email as a PDF. Not sure how and when it's happening, but sometimes it seems to change the extension of my pdf to pdf.html. It used to work perfectly before without to specify the contentType, just by mentioning .pdf in the fileName. I tried to add the contentType, but doesn't change anything. Here is a piece of the code I'm using:

Attachment att = [select id, body from Attachment where ParentId = :parentId];
Messaging.EmailFileAttachment emailFileAttachment = new Messaging.EmailFileAttachment();
emailFileAttachment.setFileName('InvoiceXXXXXX.pdf');
emailFileAttachment.setContentType('application/pdf');
emailFileAttachment.setBody(att.Body);
emailFileAttachments.add(emailFileAttachment);
...
singleEmailMessage.setFileAttachments(emailFileAttachments);
...
emails.add(singleEmailMessage);
....
Messaging.sendEmail(emails);

Anyone has ever got the same problem before?

It seems that Salesforce converts attachment to html links when total size exceeds 3Mb. This is very annoying.

  • Is it applicable to Apex email also, or only out of box emails?

  • I got the problem with Apex email only, not sure if it's the same with email workflow but I believe it's the case for every type of SFDC emails

  • In case anyone is wondering, it's still an issue in Spring 17 (API 39)
