Hello,

I am using the last version of Firefox and the Outlook online. A few days ago I was able to drag and drop file to the emails in order to attach them, but now for God's know what reason just stopped working and now when I try doing it, appears a banned sign on the mouse. I already try with other web browsers and I don't have any issue, they work fine; I also try dragging and dropping files into the Gmail in Firefox and it works. The problem seems to be only with the Outlook and the Firefox. Thanks in advance to anyone who can help me.
