Problem sending reports as atachments

[CHANCHY]

I created a report that needs to be sent as an
atachment...(I am using Access 2000), when i click the
SEND button on the toolbar it works OK in my machine...
Now i have copied the application on another manchine
that has ACCESS 2000 also,.. but when i click the SEND
button here i receive a error message:

"XXX.MBD (Aplication name) cannot open a mail section.
Make sure your email application is working properly"

I have OUTLOOK 2000 and its working OK..

What can be wrong??
