dddbug, thanks for your posts. I strongly suspect it's Evernote being ever so persistent, not an Outlook bug. If you untick and remove the OneNote plugin, it's gone for good, if you do the same with the Evernote plugin, it comes back when re-starting Outlook. Your trick with removing the dll (EvernoteOL.dll) works, but the user clearly shouldn't have to resort to such measures. Evernote is a fantastic note-taking tool, but a little consideration for all of us who aren't able to fork out for new powerful laptops and have to manage application sprawl would be very decent.
