Cannot create Subfolder in Apple mail
Whatever I tried, I cannot create a subfolder in a main folder under my Inbox. I tried right click > New Mailbox --> but the subfolder does not appear in the main folder but further down in a separate section. I have never had to deal with this before. I was always able to right click and/or go to Mailbox > New Mailbox, and it created a subfolder without a problem. Anybody knows what to do? It's an iMAC with OS Mojave 10.14.6. Thanks!
