A user was experiencing this issue. Forwarding the email back to the user and another user showed the attachment fine.

The attachment showed on mobile devices/webmail and also via a third party Outlook Attachment Add in

Looking at the headers of the email the Mime type was multipart/alternative this should be encoded to multipart/mixed

multipart/alternative is for sending text/html and text/plain versions of a message, and multipart/mixed is for adding attachments.

1) Speak to user sending mail to find out why emails are being sent as multipart/alternative

2) Create a hub transport rule to re-write multipart/alternative to multipart/mixed

changeswheremade

Recently we came across a problem where users would transfer attachments from one email to another and upon sending would get the following error

cannot open this item. changes made to the item were lost due to a reconnect with the server

The only way to send the email would be to recopying all the content to a new email and re-attach the attachments. It was though Outlook briefly lost connectivity with exchange server ( was not using cached mode ) . The connection status of Outlook showed no failed requests. We disabled all Add-on’s and started Outlook in safemode however we still got this happening randomly. In the end we applied all Office 2010 Windows updates to the terminal server and this fixed the issue!
