How can I suppress Outlook 'warning' message when sending email via c#

Posted By:      Posted Date: October 17, 2010    Points: 0   Category :.NET Framework
I am currently using the follow to send email from rich client application - not sure if this is the best solution - lack of knowledge of SMTP authentication, SMTP server etc... and wanted to utilize Exchange.

Microsoft.Office.Interop.Outlook.MailItem mail = (Microsoft.Office.Interop.Outlook.MailItem)
new Microsoft.Office.Interop.Outlook.ApplicationClass().CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
Microsoft.Office.Interop.Outlook.ApplicationClass app = new ApplicationClass();
mail.Attachments.Add(strFileNameLocation, Microsoft.Office.Interop.Outlook.OlAttachmentType.olByValue, 1, strFileNametoAttach);

mail.To = to;
mail.Subject = subject;


Everytime a message has to be send, Outlook throws up a warning message and the user needs to 'authorize' the use of outlook. Is there anyway of suppressing the warning message.

"Email message cannot be sent" error, but email still sending

I have SMTP configured corrently and can send emails with no problem. There is one place in my workflow that sends a reminder email if a task is not complete (after a Delay activity). When the reminder email is sent, I get the following error in the History Log: The e-mail message cannot be sent. Make sure the outgoing e-mail settings for the server are configured correctly. -- The weird thing is that the email still sends, and the workflow continues to run. I am using the SendMail activity rather than the SPUtility at this point (and the sendmail code used to put the email together is the same as a previous sendmail activity which works fine). Additionally, the error only happens on the first reminder, but all subsequent email reminders do not show the error and send just fine. I am also not able to catch the issue through the debugger. Any ideas?

Sending a File Using Email Helper in WebPages/Razor


Note: This is particularly with respect to Email Helper in WebPages/Razor. Please don't post links using System.Net.Mail object.

Following this tutorial: http://www.asp.net/webmatrix/tutorials/9-adding-email-to-your-website

Under "Sending a File Using Email" section what exactly is the code trying to do.

1: The SendFile.cshtml does not have any option to select file.

2: ProcessFile.cshtml is running fine. I am getting the email but no attachement.

I tried changing fileAttachment input to type="file" but not file is being sent to my email. I just get the message send in body.

Question: How exactly this file attachment works using Email Helper in WebPages.

DIME: Sending Files, Attachments, and SOAP Messages Via Direct Internet Message Encapsulation


Direct Internet Message Encapsulation (DIME) is a new specification for sending and receiving SOAP messages along with additional attachments, like binary files, XML fragments, and even other SOAP messages, using standard transport protocols like HTTP. In this article, the author explains what DIME is and how it differs from MIME encapsulation. A detailed description of the message format and how it is parsed, as well as working with SOAP and extending it with WSDL, is also included.

Sending Email by exeucting a stored proc on SQL Server that references CLR

Hi Guys, I want to modify the data type of the @body variable in the stored procedure that sends an email. The stored procedure is as follows:   CREATE PROCEDURE [dbo].[spSendMail4]<br/> @recipients [nvarchar](4000),<br/> @cc [nvarchar](4000),<br/> @subject [nvarchar](4000),<br/> @from [nvarchar](4000), @body [nvarchar](4000), @attachment [nvarchar](4000)<br/> WITH EXECUTE AS CALLER<br/> AS <br/> EXTERNAL NAME [SMTPCLR].[StoredProcedure].[spSendMail]<br/> GO   I want to change the @body variable to data type: text. The reason for this, is because I am sending an HTML email whose content (characters) exceed 8000. Basically the new stored procedure should looks like below:   CREATE PROCEDURE [dbo].[spSendMail4] @recipients [nvarchar](4000), @cc [nvarchar](4000), @subject [nvarchar](4000), @from [nvarchar](4000), @body text, @attachment [nvarchar](4000) WITH EXECUTE AS CALLER AS EXTERNAL NAME [SMTPCLR].[StoredProcedure].[spSendMail] GO   If attempt to make this change, I get the below error:   CREATE PROCEDURE for "spSendMail" failed because T-SQL and CLR types for parameter "@body" do not match.   Understandably so, because from the article http://msdn.microsoft.com/en-us/library/ms131092%28SQL.100%29.aspx CLR data type (.NET Framework) is not compa

Task assignment to user without read access in 2007 results in no email to assignee, no warning to a

It appears (from observation and searching) that SP 2007 will not send a task assignment email when the assignee does not have read access for the assigned task and there is no warning when assigning a task to someone who will be unable to read it. I have not been able to find any mentions of attempting to address this quirk by either an item event listener or a workflow that would either prevent the assignment or task the originating user to fix the issue by either changing the assignment or having them added to the appropriate group.  I could see one done badly causing a cascade of tasks. The approaches that I've thought about are: Attempt to block assignment by hooking ItemAdding and ItemUpdating on the task content type.  In ItemUpdating, you could use SPListItem.DoesUserHavePermissions since the SPListItem should be there, but you'd may have check the list since I don't think SPListItem is available at that time.  I could see this causing problems when the assignment is via workflow or something that doesn't like other code interfering with its task creation. Hooking ItemAdded and ItemUpdated to assign a new task to the assigning user to either change the assignment or have the assignee added to the users with access to the site. Define a workflow which could be enabled for a list that would check if any new or modified task is assigned to users with
