Problem Sending a report with Access 97

[Luis Marrero]

Hello, I'm having a little problem trying to send an email from access using
this line:
DoCmd.SendObject acSendReport, "Send Quote Report", acFormatRTF,
"(e-mail address removed)", , , "Test", "body Test"

Ok the problem is not an error on logic or at least i think... the error is:
Microsoft Access
Run-time error '2287'
Microsoft Access can't open the mail session.
Check your mail application to make sure that it's working properly.
Debug or End

I don't have a clue at what might be the problem since my outlook express is
working fine. May be some one has seen this error before and can help me
come with a solution.

Thanks,

Luis A. Marrero
