Outlook 2007 Will Not Send Mail From C# Application

[Dale Franks]

I have a C# Windows Forms application that I am developing. I am running

into a problem sending mail via Outlook 2007. The application is being

developed in VS2008. I work in a DoD (Navy) environment, where I have no

control over the security settings for Outlook. The code is very simple:

Outlook.Application oApp = new Outlook.Application();

Outlook._NameSpace oNameSpace = oApp.GetNamespace("MAPI");

Outlook.MAPIFolder oOutboxFolder =

oNameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderOutbox);

oNameSpace.Logon(null, null, false, false);

Outlook._MailItem oMailItem =

(Outlook._MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);

oMailItem.To = "edwin.franks@navy.mil";

oMailItem.Subject = cboSubject.Text;

oMailItem.Body = txtMessage.Text;

oMailItem.Send();

In the application I am developing, the email DOES get sent through Outlook

2003, after the user approves the mail on the security dialog box. In 2007,

however, the Send() function results in the error:

Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))

In the Outlook 2007 Trust Center, the Programmatic Access security setting

is set to "Warn me about suspicious activity when my antivirus software is

inactive or out of date (recommended)", which, although I cannot change it in

the Outlook interface, seems to me to be the appropriate level of security.

I really don't care if the security dialog box appears or not. It does

appear in Outlook 2003, and the user can approve the message. That's fine.

What I don't understand is why Office 2007 refuses to either send the email,

or provide a security dialog box for the user to approve it. I can save the

email. I can move it into the Outbox, or anywhere else. I can display the

email, and have the user manually click the send button. But I can't

actually send the email.

Since the rest of the organization is scheduled to upgrade to Office 2007 in

the near future, this is a matter of some pressing interest for me.

Any suggestions?

What does Tools | Trust Center tell you about the status of your anti-virus

application?

Have you tried adding a Namespace.Logon statement? That may be necessary if

Outlook isn't already running.

I've also seen people report good results from displaying the message before

adding recipients and sending.

My anti-virus software is up to date, according to the trust center. I did

add the line to display the message prior to adding the recipient addresses

and body text. It did display, and was correctly contstructed. The Send()

function still resulkted in the same error. I can do everything imaginable

to the message...except send it.

Although after the message displays, I can hit the send button on the

displayed message form, which sends the message promptly. It just won't send

programmatically.

The code already has the Namespace.Logon() command incorporated.

Namespace.Logon should be invoked before any statements that use the

instantiated Namespace object. Also, if Outlook isn't already running, you

may need to prompt the user to choose a mail profile.

The only other thing I can think to try is calling Recipients.ResolveAll

before sending.

BTW, is there a particular reason why you're using Outlook and not

System.Net.Mail?

Yeah. As I mentioned, I'm working in the US Navy NMCI environment. I'm not

allowed to touch an SMTP server. And, even if I could, the SMTP ports are

blocked anyway.

Dale,

I have the same problem. If have resolved please suggest your solution that

fixed your problem.

My problem:

When I send the Email programmatically (C#) through Outlook 2007, it throws

Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))

error and did not send the mail.

As when OUTLOOK 2007 process is started in the background, the same

application sends successfully the email.

The same application sends the email on another machine where OutLook 2003

is installed, without the outlook 2003 process started in the background.

I appreciate your solution.

Thanks,

SAM

I found a soultion for my problem.

For Outlook 2007, the code needs Outlook.Inpector object.

Outlook.Application oApp = null;

Outlook.MailItem oMsg = null;

Outlook.Inspector oAddSig = null;

oApp = new Outlook.Application();

oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);

oAddSig = oMsg.GetInspector;

After adding Inspector object the code sends email through Outlook 2007.

That is the solution to my problem.

With Outlook 2003, the code does not need this Inspector object. Without the

Inspector object, the Outlook 2003 sends email.

Sam,

I have a similar problem with my VB5 program using MAPI trying to send Email

thru Outlook 2000. I have an unanswered post below but wondered if you could

help.

I have a VB5 pgm that uses MAPI to send emails to customers. Everything

works fine when "Outlook Express" is installed on my XP computer. When I

replaced Outlook Express with "Outlook 2002", it appears that my pgm sends

emails out just fine, but when I click Outlook I get an error message "System

Administrator: None of your e-mail accounts could send to this recipient."

What is wrong and how can I fix this?
