Hi - same problem for me.
How can I move notes that I've emailed to myself (I have a pro account) to another notebook? My other notebooks appear in the drop down, but are greyed out and with a padlock symbol.
The owner of the notebook has shared it with me and I can create new notes in there and view all the content. The problem occurs whenever I've emailed a note to myself and then want to assign it to the right notebook.
It would be helpful if someone at Evernote could reply and confirm if this is a known limitation or if it *should* work.
Thanks
