Send to under file Missing in Office 97′

Hello,

My client workstations are NT4 with Office 97′ installed without Outlook. e-mail client that is utilized is Outlook Express 5.5 or 6.X

In Office 97′ (whatever Application: Word, Excel, etc.) under file, send to there is a option called Mail Recipient. On some of my machines when you click on this, it will automatically launch Outlook Express & the document will be in the e-mail as an attachment. But then again, on other machines, either the Mail Recipient is missing altogether or when you click on Mail Recipient, it starts you through the e-mail account setup process under Win NT Control Panel, Mail & Fax, but does not link itself to Outlook Express when you click on Mail Recipient in the future…

Any idea what I could bemissing here?

Thanks,

Aaron
