Box for Outlook integration needs to support moving multiple emails to a box folder, currertly only one email can be filed at a time. Also you only have the option of saving the email message as an .eml which is frustrating as these file dont preview within Box Web. Are you able to have an option for .msg.
Another great use would be able to move the email to Box rather than a save, which ultimately a copy.
Also ability to show some box folders in Outlook and drag and drop to those folders would be a great feature.
