You can send emails from within Workbooks that 'appears' to come from a different address from your usual login email address by setting up a new email account. As an end-user you can set up your email accounts within your Preferences (click Start > Preferences) or if you have System Administrator capabilities you can set up email accounts for other users within Configuration.
