How to Reply to a Message in Windows Mail
The easiest way to follow up on an e-mail message you receive in Windows Mail is to reply to it. When you reply to a message, Windows Mail takes all the heading information from the original message and uses it to create the response heading. The only thing you have to do is fill in the message.
Open the message you want to reply to and then select one of the following reply options:Reply to the sender or all recipients.
Reply: Send the reply to only the author.
Reply All: Send a reply to the author as well as everyone who received the original message.
In the resulting e-mail form, enter any additional recipient(s) in the To and/or CC text boxes and type your message in the message window area.
Windows Mail automatically includes a copy of the original message at the end of your new Reply message. This helps everyone now what you're referring to. However, if you don’t want to include the original message in your reply, choose Tools→Options and click the Send tab. Clear the Include Message in Reply check box, and then click OK.
Click the Send button to send the reply.
