I'm trying to edit a presentation a colleague shared with me but can't get it to open with Poweerpoint for the web tool. I see the file icon in my folder. It opens in the browser when I click on it. Chosing the Open / Powerpoint for the web button opens a new tab which sometimes asks me to log into my MS Online account, which I do. I then get a loading page that seems to refresh itself for many minutes, before finally giving an "Ooops something went wrong" error. The tab is labelled "undefined - Excel for the web". (Viz., Excel not Powerpoint.) Any ideas?
I am using Firefox on Windows 7. I have tried quitting Firefox and opeing again in private mode. Neither Powerpoint and Excel are open on the workstation.
Thanks.
