Cannot change thread mode after it is set

[sjakiePP]

Hello,

Above is the exception that I receive when I want to open a new MAPI session, to retreive the global address book from the exchange server. I am building an Outlook add-in, the version used is 2003

I tried to add [STAThread] to the methods used, but this had no effect. What could this be?

Thanks in advance.

try {
	MAPI.SessionClass oSession = new MAPI.SessionClass();	//session
	oSession.Logon(System.Environment.UserName, System.Reflection.Missing.Value, false, false, System.Reflection.Missing.Value, false, System.Reflection.Missing.Value);	//login

	// You can select one AddressList, 
	// by changing the last enumerated type
	// selecting global addres list
	// MAPI.AddressList oAddressList = (MAPI.AddressList) oSession.GetAddressList(MAPI.CdoAddressListTypes.CdoAddressListPAB);
	MAPI.AddressList oAddressList = (MAPI.AddressList) oSession.GetAddressList(MAPI.CdoAddressListTypes.CdoAddressListGAL);
System.Diagnostics.Debug.WriteLine(oAddressList.Name);
	MAPI.AddressEntries oAddressEntries = (MAPI.AddressEntries) oAddressList.AddressEntries;

	for(int j = 1; j <= (int)oAddressEntries.Count; j++) {
		MAPI.AddressEntry oAddressEntry = (MAPI.AddressEntry)oAddressEntries.get_Item(j);
		// Print out each AddressEntry name
		System.Diagnostics.Debug.WriteLine(" " + oAddressEntry.Name);
	}

	oSession.Logoff();
}
catch (System.Exception ex) {
	System.Diagnostics.Debug.WriteLine(ex.Message);
	System.Diagnostics.Debug.WriteLine(ex.StackTrace);
	System.Diagnostics.Debug.WriteLine(ex.Source);
}
