After installing a recent security update, KB3128008, or after updating the Click-To-Run version of Office 2013 to build 15.0.4885.1001, Excel 2013 customers see the following error when they try to send a workbook using the File > Share > Email > Send as PDF or File > Share > Email > Send as XPS commands.
"General mail failure. Quit Microsoft Excel, restart the mail system, and try again."
On January 10, 2017, we released an Office 2013 update that fixes this issue.
If you receive Microsoft Installer (.msi)-based updates for Office 2013, download and install the January 10, 2017, update for Excel 2013 (KB3141475).
If you receive Click-to-Run updates for Office 2013, update to version 15.0.4893.1002. You can either wait until you’re prompted to install the update or get it immediately by clicking File > Account > Update Options > Update Now.
