Hi to all,

I have developed a software (CRM) and sending quotations from Microsoft Outlook.
All the mail credentials for the mail comes from server pages.
I have used 'Microsoft.Office.Interop' namespace.
Following is the code for reference :-

Imports System.Net
Imports Microsoft.Office.Interop.Outlook
Imports Microsoft.Office.Interop

    Public Function OutlookCall()
        Dim pdfFile As String = "c:\Quotations\Quotation for #" & Session("QType").ToString + " " + Session("CustEnqID").ToString & ".pdf"
        'Take an instance of the Outlook App 
        Dim oOutlook As New Outlook.Application()
        ' Create an instance of the MailItem 
        Dim oMailitem As Outlook.MailItem
        ' Create an instance of the Attachment 
        Dim oAttach As Outlook.Attachment
        oMailitem = oOutlook.CreateItem(Outlook.OlItemType.olMailItem)
        oMailitem.To = Session("EmailID").ToString
        oMailitem.CC = "abc@abc.com"
        oMailitem.Subject = "Quotation from Abc Pvt. Ltd."
        oMailitem.Body = "Please download an Attachment for quotation requested Abc Pvt. Ltd."           
        'txtFilepath is a text box that contains the path for attachment. 
        'Attach the file Path to the Mail Item 
        oMailitem.Attachments.Add(pdfFile)
        'PING….Displays the Outlook along with the To,Cc,Subject and Attachment 
        oMailitem.Display()
    End Function

Then I used this function on local machine it works properly, but when I publish this on IIS, it displays an error as :-

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005.

Please guide...
Thanks in Adv.
