Thank you for your feedback
When you need to sort your mail, you may not see the options to sort by Sender, Subject, and Attachments. This is due to Conversations being enabled. If you wish to be able to sort messages using all available options, go to your business email settings and disable Conversations. Note: You will also need to disable Conversations in order to view email headers.
Note: The Conversations feature is only available in Full-featured Mail.
