SUMMARY I have 3 active email account 2 iCloud and one Gmail account. The Gmail account functions without issue. Both iCloud accounts send / receive with no issue and the deleted messages properly route to the assigned Trash folder for each account (not the local folder). Upon deleting a message the message moves to trash as expected, but leaves a greyed out message in the inbox. STEPS TO REPRODUCE 1. Delete email (also tried deleting message thread and move all messages to Trash same result). 2. Check Trash - it's there, back to inbox it's there too but greyed out. OBSERVED RESULT Duplicate email in the inbox when the mail is moved to trash. EXPECTED RESULT Email should be moved to trash without being left in the inbox.
