Dear all,
thanks for your answers.
Dear rjkrash,
I am aware of that article by microsoft, but I also saw the Outlook context menu being changed by an add-in, which really bothers me, as if I had not seen it, I just could believe and tell my boss, that it cannot work at all. :-(
Could it be , that there are special means in an add-in that I am not aware of? I am really not familiar with add-inns! Any ideas?
regards Astrid
