Old Deleted Emails Appearing in Inbox
Note: You may see old emails that you've deleted, appearing in your inbox marked as "unread". These emails were probably deleted from your Inbox and added to your Trash. However, if the Trash was not emptied prior to the migration then those emails were copied over. They are not duplicates or an indication of any further or ongoing issue. Simply delete them again. You can empty the Trash or not, after. That only affected the Migration and not normal operation.
