It must have worked 2-3 years ago as the older notes are backed up on Outlook.
On the iPhone: Settings: Notes I changed the Default account to "on my iPhone" instead of "Gmail". Now new notes are no longer emailed to me. Also new notes are backed up on Outlook when I sync using iTunes. But the notes from the last 2-3 years still do not backup/sync with Outlook. Might this have something to do with the 3 Accounts on the iPhone Notes app (all notes, gmail, from my PC)?
Yes. But how can I get the notes that have not yet backed up to sync with Outlook?
It appears that if I copy and repaste older notes as a new note, then the new note will backup to Outlook.
