Mail.app on Mac corrupting PDFs A co-worker is having an issue where PDFs sent as attachments are being corrupted.  If opened through webmail, the attachment is fine.  Any ideas here?

I've rebuilt the Mailbox (using Mail.app's built in feature), but it happened after it.

Happening to PDFs randomly and a powerpoint.
I had a similar issue at one point. 

Try clicking the save button on the top-right corner of the email and designate where to save the files. Then open the file through finder (instead of just clicking on the pdf within the email). This worked for me.
