How to Create and Add a Signature in Windows Mail
Creating and adding a signature to your Windows Mail messages is a time saver. When you create and add a signature in Windows Mail, it lets you include information to the bottom of all of your e-mails with just a click. This information could include all of your contact information, just your name, a favorite quote, etc.
In Windows Mail, choose Tools→Options.
The Options dialog box appears.
Select the Signatures tab and click the New button to create a new signature and then enter your signature's text in the Text box.
If you have different e-mail accounts and want to assign a different signature to each one, click the Advanced button and then select an account to associate this signature with.
Select the Add Signatures to All Outgoing Messages check box and make sure that the signature is selected as the default. Click OK to save the signature.
Select the Don’t Add Signatures to Replies and Forwards check box if you want to add your signature only to e-mails that originate from you.
If you attach your signature to every outgoing e-mail, including e-mail replies, whomever you communicate with will get the information provided there. Consider issues of identity theft before you provide your address, phone number, and other personal information to all.
To manually add a signature to an open e-mail message, choose Insert→Signature and select a signature from the list that appears.
Then just finish writing your e-mail and click Send.
