I have a numbers spreadsheet on my mac. I cannot connect the mac to my network, which is all windows. I want to email the spreadsheet to another mac. I tried copying the document to a thumb drive and then plugged the drive into a windows machine. I attached the doc to an email and sent it. The receiver of the email said the spreadsheet wouldn't open because it was missing some files. Does anyone know how I can email this spreadsheet? I have to use outlook, no web mail is accessible, and I do not want to export it to excel. Any suggestions?
