I have disabled virus scan (McAfee Enterprise) and I still have the same problem. There will be a file on the share but the size will be 0K. The application will act like it is saving the file and then pop up a window saying 'document not saved'. If the MP4 and MOV options aren't in your version of PowerPoint, see Requirements below for more information. I tried saving to the 'group share'and his Home directory and I get the same thing. (Don't use Save As, because it doesn't offer video options.) Open the File Format list and select the video format that you want (MP4 or MOV). No changes have been made to his AD account or permissions on the shared drive. I opened Notepad from his machine and created a txt file and saved it just fine out to the network drive with no problems but the Office applications will not save to the network. He can save it to his desktop (or local drive) and copy it out the the share through Windows Explorer, but he can't save directly to the network from the application. When he is in Excel or Word, and creates a new document or opens an existing document (locally or off of a network share), he can't save that document to ANY network drive.
