Creating and Using Multiple Signature Files

1. First, follow steps to create multiple mail signature(s).
2. Select Tools > Options. The Options dialog box appears.
3. Select the Mail Format tab.
4. Click Signatures... The Signatures and Stationery dialog box appears.
5. In New Messages or Replies/forwards, select the signature you want to use for each of these actions from the pull down menus.
   
   

If you'd like to set a different signature while writing a new message:

1. Select File > New > Mail Message.
   Note: If the "From" field on the message is not already displayed, select Options> Show From.
   
2. Select Insert > Signature and select the signature you'd like to use for this message.
