You can reply to a received message by selecting the message and pressing the
button located in the Shortcut bar in Mail mode. When you do this, the view will switch
to Compose View and OfficeTalk will automatically set up the subject, prefixed with 'Re:', and will copy the original text positioning the caret ready for you to type in your reply. The
original sender of the message will be set up as the recipient of the replying message. Once you have entered your reply into the message window, press Ctrl+S to send the message.
Note: You may also reply to a message by clicking the right mouse button on the message and selecting Reply from the context sensitive menu.
The 
button may be used to reply to the author of the original message. If you wish to reply to both the author and all the recipients of the original message, then select the
message and press the 
button. This will behave exactly as described above except that all the recipients of the original message will become recipients of the new message.
Note: When you reply to a message, any attachments in the original message are also included in the reply message.
