Adodb Connection To Outlook Calendar Appointment

I'm connecting to Outlook using Adodb. (ADO is a requirement)

  With ADOConn
     .Provider = "Microsoft.JET.OLEDB.4.0"
     .ConnectionString = "Exchange 4.0;" _
                                & "MAPILEVEL=" & mailboxname & "|;PROFILE=Outlook;" _
                                & "TABLETYPE=0;DATABASE=C:\WINDOWS\TEMP\;"
     .Open()
 End With

then using the sql

   Select * from Calendar 

which returns the Appointments, but with no start or finish times.

Does anyone know how I can retrieve this information this way?开发者_如何学Python

Do you have to use ADODB? If not, you can try this:

Dim ola As New Outlook.Application
Dim oln As Outlook.NameSpace = ola.GetNamespace("MAPI")
Dim olc As Outlook.MAPIFolder = oln.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar)
For Each item As Outlook.AppointmentItem In olc.Items
    MsgBox(item.Subject & vbCrLf & item.Start & vbCrLf & item.End)
Next

If you do have to use ADODB, then can you post the portion of the code where you are trying to read the start and end times?
