Hi everyone, 
  I try to use exchange server 2003 SDK, I install the SDK on the VMWare of the exchange server itself. I run the one of the sample(calendaring), the problem pop up.
"
3709
        List appointments threw the following:ADODB.Record:The connection cannot be used to perform this operation. It is either closed or invalid in this context.

"
when i compile the sample, the yellow error line point to the"dim flds as ADODB.Fields"
anyone know what is the problem.
