Apple Mail: Manually moving mails to local mailbox copies them instead of moving
I just got a new MPP 16" with Monterey and I realized that Apple Mail copies e-mails instead of moving them if I activate them, then right-click with the mouse and use the pop-up window offered by 'Move to'. The message stays in the in-box and I see 'Undo Copy Message' under 'Edit' in the Menu Bar on top. The messages are correctly copied if I use the 'Move to' popup-icon on the Toolbar or the 'Move to' proposal from the popup menu upon right-clicking on the message. Restarting Apple Mail or the computer doesn't solve this problem. – Does anyone else have this issue too? Can it be solved?
