Hi,

I am trying to send outlook mail from a c# web application. When I am debugging the code, it runs fine. I have even used same for console application and it works fine too.
But when I deploy the application on IIS, I get this error:

C#

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)). 

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. 

To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

All I understand is there is a failure to load COM object which isn't happening in debugging. So what can be the possible reason for this? Any solution or work around will do.

Thanks..!!

What I have tried:

Somehow below code not working after running from IIS.

C#

Microsoft.Office.Interop.Outlook.Application olapp = new Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.MailItem msg = (Microsoft.Office.Interop.Outlook.MailItem)olapp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
            string body = "";

            msg.Subject = "new message";
            msg.To = "xxxx@yyy.com";
            body = "test msg";
            msg.BodyFormat = Microsoft.Office.Interop.Outlook.OlBodyFormat.olFormatHTML;
            msg.HTMLBody = body;
            msg.Display();
            msg.Send();

The error message is telling you what needs to be done. But you really need to understand the restrictions on web sites and servers.

I have given full permission to iis users from outlook command button control properties in DCOM config, as I saw in another solution. But still it is not working. I am not aware of restrictions of sending mail over web. It is working fine in debugging mode.

Your code is running on the server so it is trying to send email from the server's Outlook profile, not from the person using the site. Chances are you have not set up the Outlook profile from the server, and chances are this is not what you're wanting either, you probably want the email to be sent from the client's Outlook. You can't do that and you can't automate Outlook from your asp.net code, you need a different solution like sending email via your .net code and the SmtpClient, or using Exchange services if your client's are using Exchange. You have to remember that outlook is a client application and your server code can manipulate it no more than it can Word or notepad.

I want to send a mail to user when user clicks a button. That's all. If there is any other way apart from outlook, I'll be glad to try it.

After giving permissions, the old error is gone. Now this error is coming:
Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80010001 Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED)).

Automating Outlook from asp.net is not supported, you will not get this working reliably.

Is there any other option?? I will try if there is. I am now trying to send mail using gmail. But it is giving time out error.

F-ES Sitecore 2-Aug-16 6:50am

Don't send email through gmail, if it's an internal network your network admin will tell you an smtp server you can use.

Philippe Mori 2-Aug-16 9:47am

In .NET, you have all you need to send email from ASP.NET. You don't need to use Outlook. All you need to so is to type something like send email from asp.net in your preferred search engine.

As other have mentioned, it is well known that Office automation should not be used on a server. It was not designed for that purpose.

I have tried various examples as per your suggestion with gmail. Every time it says "the remote name could not be resolved". When I try pinging gmail.com it says request timed out. Server is in intranet. Could that be a problem?

planetz 3-Aug-16 2:54am

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.125.136.109:587

This is the error coming now.

Philippe Mori 3-Aug-16 9:09am

Well you have to ensure that all parameters are valid like EnableSsl and the port number. One way to confirm parameters is to try with an existing application to ensure you get it right. Also, you have to ensure that no firewall or whatsoever block the access. Your network administrator should be able to help you.

planetz 2-Aug-16 6:47am

Also I would like to inform that the server is in intranet network.

Put your code in a code block to make it more readable.

As mentioned in comments, your code is running on a server and so Outlook would have to be setup on the server with a profile, etc. But this is a terrible idea, so, you asked for another way. Sending SMTP email is very easy in ASP.Net. There are tons and tons of examples online. Here is the first result when I search google, How to send email in ASP.NET C# - Stack Overflow[^].
