Outlook Redemption and safeMail hangs on exit

I have a problem where my app is hanging on exit when I try to use saafeMail. If I run the code in the debugger the program exists normally, but when I run outside the debugger it hangs at exit.

RDOSession session = RedemptionLoader.new_RDOSession();  
session.Logon(null, null, false, null, null, null);  
Outlook.Application outlookApp = new Outlook.Application();  
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");  
Outlook.MailItem newMail = outlookApp.CreateItem(Outlook.OlItemType.olMailItem) as  Outlook.MailItem;  

SafeMailItem safeMail = new SafeMailItem();

safeMail.Item = newMail;  
safeMail.Recipients.Add("[email protected]");  
safeMail.Recipients.ResolveAll();  
newMail.Subject = "Subject";  
safeMail.Body = "TextBody";  
safeMail.Send();  

Thread.Sleep(1000); // tried to add this to allow any pending COM operations to finish

Marshal.ReleaseComObject(safeMail);  
Marshal.ReleaseComObject(newMail);  
Marshal.ReleaseComObject(outlookNamespace);  
Marshal.ReleaseComObject(outlookApp);  
session.Logoff();  
Marshal.ReleaseComObject(session);

I guess there is a problem releasing COM objects? Any ideas here?

Solution

  • You are still leaking a COM object reference since you are using multiple dot notation. Replace the following lines

    safeMail.Recipients.Add("[email protected]");  
safeMail.Recipients.ResolveAll();

    with

    var recipients = safeMail.Recipients;
var recip = recipients.Add("[email protected]");  
recip.Resolve();
Marshal.ReleaseComObject(recipients);
Marshal.ReleaseComObject(recip);

    You can also create a recipient in a resolved state using

    var recipients = safeMail.Recipients;
var recip = recipients.AddEx("jon", "[email protected]", "SMTP", OlMailRecipientType.olTo);  
Marshal.ReleaseComObject(recipients);
Marshal.ReleaseComObject(recip);
