Send To Mail Recipient

I’m using Office 97 with Outlook 2000 on a Windows 98 Machine. Outlook talks to an Exchange 2000 server. When I click the ‘Send To Mail Recipient’ option from within an Excel or Word document, a new e-mail is created and a copy of the document is attached, but I don’t have access to the Global Address List on the e-mail server.
If I open Outlook and create the e-mail manually, then I see the list of company employees in the Global Address list.

Any reason why it wouldn’t work from within Excel or Word?

Note ? All the other PCs in the company are Windows XP Pro and they don?t have that problem.

Thanks
