Description
Outlook users can create and use signatures in email messages. Users can add signatures to messages manually, and can also configure Outlook to automatically append signatures to new messages, to replies and forwards, or to all three. Signatures typically include details such as the user's name, title, phone numbers, and office location. When an organization has policies that govern the distribution of this kind of information, using signatures might cause some users to inadvertently violate these policies.
