aspx thread: Re: - Trouble using CDO from ASP.NET

I'm having the exact same problem using CDO from a class called from an
ASP.Net (using C#). I do know that if the profileInfo is left as an empty
string, then I get a different error (MAPI_E_LOGON_FAILED).
Any clues would be greately appreciated.

Thanks to your error translation, I think I've figured it out - you need
to initialized the session and logon in a separate thread. Here's the
code that seems to work for me - then I just have to check fLoggedOn
before using the session object.
private Boolean fLoggedOn = false;
public COutlook()
{
//Class initialization - this code could go anywhere
ThreadStart start = new ThreadStart(InitSession);
Thread t = new Thread(start);
t.Start();
}
public void InitSession()
{
if (oSession==null)
{
try
{
String sProfile = "myServer" + System.Environment.NewLine + "myAccount";
Thread.CurrentThread.ApartmentState = ApartmentState.STA;
oSession = (MAPI.Session)Activator.CreateInstance(Type.GetTypeFromProgID
("MAPI.Session"));
oSession.Logon("myUserName","",true,false,-1,true,sProfile);
fLoggedOn = true;
}
catch (System.Exception e)
{
throw new System.Exception("Error initializing Outlook\n"
+ e.Message + "\n" + e.StackTrace);
}
}
}

Oops, spoke too soon. Despite the fact that the session object has class
scope, I only seem to be able to use it in the thread that initializes it,
so this still doesn't seem a viable solution.
