Where does "Move to All Mail" move messages to?
Sometimes when I receive an email in macOS Mail, the move to button suggests "All Mail":
Where does that action move messages to? After I click it without selecting a specific mailbox, I can't find the message anymore. It doesn't go to Archive. It seems to be effectively deleted without going to Trash. A search for the message in all mailboxes will not find it. Also, I cannot seem to find any documentation for this behavior. Can anyone help? Thanks in advance!
I am using an iCloud email account on macOS 10.14.6 (18G95).
