You can remove all unnecessary quoted text from email messages by selecting the option:

  • Remove all quoted text in replies and forwards

When this option is enabled, all quoted text will be stripped from replies and forwards. For example, the email message like this:

Hi, 
How are you?
Cheers,
Bob
