After you have clicked the menu item "Messages", you have the option to compose a new e-mail.

By clicking "Save as Draft", this e-mail will not be sent but will be saved in the "Drafts folder".

The overview will always display the e-mails which you have saved as a draft. Read your drafts by clicking on the corresponding message. Another click will open your draft for further editing and for sending.

To delete a draft, select it by means of a single click. Now click the "Delete" button. The draft has now been removed.
