I have Windows 10 Pro, Office 365 ProPlus installed and when I am in Outlook and click on attach a file or drag and drop a local file to a mail, there is no option 'Upload to OneDrive'. See picture. My collegaues do have this option. Why is this missing? I am signed in in Outlook with my Offce 365 accounts and when I click on Attach File, I do have the Browse Web Locations and I see my recent OneDrive files as well.
