Move "On My Mac" Notes to IMAP account possible? Getting error msg.

Question

I have 2 IMAP mail accounts, 1 work & 1 personal. I use Notes extensively & Compose Options is set to Account of Last Viewed Mailbox, but due to also extensively using smart folders, when I create a new Note, it is created "On My Mac" rather than in the last mailbox.
I would like to move the local Notes to either the Work or Personal accounts (depending on the note), however, when I drag the Note from Notes parent folder to the Work or Personal Notes sub folders I receive an error message:
The message "<name of the note>" could not be moved to mailbox "(null)". The destination mailbox does not exist.
It says this regardless of the fact that a Notes folder exists on the server in the same root as specified in the IMAP account settings.
I can store new notes on a specific Server by changing the Compose option above, but obviously this doesn't help with the numerous existing notes, and I would lose flexibility for creating notes for either account (without annoyingly switching between them in Options every time I create a new note).
Last thing, this workflow (dragging from local to server) works fine for ToDo & Messages, only Notes is failing.
Anyone with ideas? I would like Notes to work pretty much exactly as ToDo, where they have their own folders (not stored in the accounts Inbox).

Answer 1

Immediately after posting this, I unchecked the Store Notes in Inbox setting for the IMAP accounts, and after doing so, I can freely drag notes onto Notes IMAP account sub-folders... so looks like the problem is resolved!
Posting here, in case anyone tries similar and gets the error message I was seeing. Hope this helps!
