Just tell them to stop being cheap bastards and upgrade to the latest version of Office. My work computer has Office 2007 and it supports Open Document Format.If a Mac user can't open a .odp file it's fine and I'm the bad guy because I don't use .ppt.
If I ask students to upload presentations in pdf instead of pptx they just ignore me.
