I use Microsoft Outlook 2013 and when I get mail with an attachment and I open the attached file (mainly Word and Excel documents), they open only in read only mode.
I want them to open in read/write mode, so that I can edit the file and save the file with the same filename and in the same location.
P.S. The temp folder is default, system temp folder and I am not able to change it.
How can I get the above written result?
