I work three part time jobs, and all three use OWA. For the past year, I have not been able to attach a file using Chrome. As a fix I used IE, because no one seemed to have a solution at the time. I still can't find one. Now, with Windows 10, same thing happens when I use Microsoft Edge. The work around on this is to "open using internet explorer" which worked. Firefox does not have this problem. Anyone have a solution? I work with computers as a hobby and still can't seem to find a solution.
