Outlook XP won’t send page by e-mail

I have a user with Outlook XP that is trying to send a web page as an email. The whole process is: He has an email with a link to a web page. Link opens Internet Explorer. In IE, click on File / Send / Page by E-mail. Outlook starts a new message, put in a email address, but when you click the Send button, nothing happens. Outlook will send email normally as he forwarded me a copy of the email with the link. Also, you can copy the web page and paste it into an Outlook message and it will send.

I have looked through the security settings in Outlook, but don’t know what to look for. The user states that he can do this at home. Any ideas?

Thanks!
