No "Share" option on Excel 2010 File dropdown menu
I can convert an Excel 2010 worksheet to a PDF with the Save As option or the Print menu, choose PDF, select Printer Properties etc, but I understand there is another method involving the Share option on the File dropdown menu, except I have no Share option. Can anyone tell me how to enable the Share option? Ultimately, I want a single click option to print my worksheet as a PDF in the smallest size. Thanks for any help.
