Forwarding of email with attachment (PDF) using new webmail interface removes the attachment

When I forward an email with an attachment (PDF) using the new webmail, although the attachment is shown at the very bottom of the email, the recipient only gets the text and no attachment

I tried an experiment and added a second attachment manually from local folder and sent once more, the manually added attachment (JPG) was delivered but the PDF was once again missing

I switched back to the older version of webmail and forwarded the original mail again, with the singe attachment and it worked fine. PDF delivered without issue

I had also tried to forward the same email on my iOS9 device. The response was rejected by server. I use ActiveSync on my phone not IMAP (employer doesn't allow IMAP over network)
