ESP OWA simulation not sending messages   

Any ESP gurus out there?  I'm trying to run an OWA load simulation with
the OWASuite in ESP.  Login and read operations are succeeding, but not
sends.  When the script tries to post to the Drafts folder with this
line:

POST /$vroot$/$USER$/$Drafts$ $filepath$SendMsgTo4Data.1 replacevars

I get a successful HTTP status in the logs:

2006/05/22 13:55:12:428,ltcy       , clnt    0, cmd POST
/exchange/Leuctd10aa/Drafts, resp HTTP/1.1 401 Unauthorized
2006/05/22 13:55:12:677,ltcy    253, clnt    0, cmd POST
/exchange/Leuctd10aa/Drafts, resp HTTP/1.1 401 Unauthorized
2006/05/22 13:55:12:687,ltcy     10, clnt    0, cmd POST
/exchange/Leuctd10aa/Drafts, resp HTTP/1.1 200 OK

but I can't find the message anywhere.  It's not in Leuctd10aa's Drafts
or Sent folder and it's not in the inboxes of any of the recipients.

I believe that the first two 401's are ok because I see the same
behavior when manually sending from IE.  The manual send succeeds and
the message sent from ESP disappears.

Does anyone have suggestions for figuring out what's going wrong?

Thanks,

Boris
