With the recent Evernote update, I'm able to go in and activate through Outlook 2013 64 bit "COM add-ins" by turning the checkbox on, and the Evernote button appears, and works, as folks are starting to report. But if I close Outlook 2013 and then start it again, the add-in (and button) are gone again, I have to re-do the manual activation all over again. Not sure why (other activated add-ins are sticky and working, meaning, the checkbox/add-in stays active, even after restart). I'll fiddle with it more later tonight, meanwhile, anybody find an easy solution to get it to stick? Over here, gopher_2013 also reporting it's resolved: http://social.technet.microsoft.com/Forums/en-US/officeitpro/thread/3a46c326-b336-4ec9-a0e7-58905064260e/#0f3bef9d-caf8-4a3f-a02f-8aff00c4ccce but unclear to me if that person is a 32 bit or 64 bit Outlook 2013 user.
