Exception thrown on MailItem.Send bstrum 6/1/2007 3:42:01 PM I am getting an exception thrown with our c# outlook addon installed on one machine running Office 2003. The exception is thrown when I try to call Send on a mail item that I have programatically created. The code looks like this: Note: This code uses late binding. // -- in the Item_Send event -- MSOutlook.MailItem mi; // assume initialized from the Item_Send argument // create the new mail item that will be programatically sent object otmp = mi.Application.CreateItem(MSOutlook.OlItemType.olMailItem); MSOutlook.MailItem m = (MSOutlook.MailItem)MO.COMWrapper.Wrap( otmp, typeof(MSOutlook.MailItem)); m.BodyFormat = MSOutlook.OlBodyFormat.olFormatHTML; m.To = mi.To; m.Subject = "Some subject"; m.Body = "Test Body"; m.Save(); m.Send(); // throws exception on one client computer The actual exception thrown is "Exception has been thrown by the target of an invocation." I have tried everything I can to duplicate the exception in our test environment to no avail. Any ideas why something as simple as this would throw an exception? Thank you, Ben Strum ThinkTron Corporation

Re: Exception thrown on MailItem.Send bstrum 6/5/2007 1:49:03 PM The ResolveAll call is returning false on this one machine so the email does not go out. Why would this happen? How can I get around this? I am sure that the email address specified is valid and even if it is not, so what? Lastly, is there a way to duplicate this in a test environment? Getting a fix for this is really slow because it only happens on this one machine at a client site.

Re: Exception thrown on MailItem.Send "Sue Mosher [MVP-Outlook]" <suemvp[ at ]outlookcode.com> 6/5/2007 2:54:03 PM This is not an appropriate way to copy recipients: m.To = mi.To; There is no guarantee that the display names, which is what To shows, will resolve to valid addresses. Instead, you need to iterate the mi.Recipients collection and use m.Recipients.Add to create a new Recipient based on the information from the original item. To test, use one or more recipients whose display names are radically different from their actual email addresses. -- Sue Mosher, Outlook MVP Author of Configuring Microsoft Outlook 2003 http://www.turtleflock.com/olconfig/index.htm and Microsoft Outlook Programming - Jumpstart for Administrators, Power Users, and Developers http://www.outlookcode.com/article.aspx?id=54 "bstrum" <bstrum[ at ]discussions.microsoft.com> wrote in message news:5134F1F0-AF4D-48F9-AF2C-4929C408A518[ at ]microsoft.com...
