I have a user who is unable to open .Xlsx files from our SharePoint 2013 Online page. When she clicks on any Excel document (xls or xlsx) in Microsoft edge it gives her the error: "You need a new app to open ms-excel" If she tries to open any file in Internet Explorer it just crashes the browser entirely.
The user is using Windows 10 and Office 2010 Home and Business. I've already tried clearing the settings, resetting the defaults and repairing office.
Any help would be appreciated.
