Note:

insert is AutoText that comes from the name and information that you typed
when you installed Microsoft Office. To view the information in Word, on the
Tools menu, click Options, and then click User Information.
When you use Word as your e-mail editor and you have Outlook automatically
apply your signature to messages that you send, forward, or reply to, the
signature comes from the e-mail signature that you created in one of the
following places:
In Word, on the Tools menu, click Options, click General, and then click
E-mail Options.
In Outlook, on the Tools menu, click Options, click Mail Format, and then
