Use “Save As” any email attachment or Document to SharePoint List
Your best bet is to add the SharePoint library as a Network location in your Windows Explorer. In windows explorer, right click on
Computer –> Add Network Connection –> Add custom location
(use the SharePoint library url).
This allows you to use “save as” from any of your desktop applications
(including Outlook and browser) to select your SharePoint library as well as using “Attach File” in an Outlook email to select files from the SharePoint library.
This would also eliminate the need to have SharePoint open.
