I am trying to move all of my On My Mac folders (Mail.app) onto my IMAP account. I have one folder with sub-folders that has copied all the subfolders. However, the main folder is white and hasn’t copied the emails, nor will it allow me to drag/drop into the main folder. Any ideas?

Dunno. Have you tried to just copy the emails in the folder themselves? Rather than the whole folder?
