The option to recall a message should be available while viewing the message, not just from the Sent view.
Currently, the only place the option to recall a message appears is in the actions bar of the Sent view. Nowhere else. This action should also be available when a sent message is opened.
Please create a tool bar Icons for Mail / Message recall and email encrypt.
These icons should be displayed when composing a mail (Encrypt) or when user opens a mail which was already sent (Recall).
