I would like that a button click on an ASP.NET page opens a new mail with the default mail client, filled with an HTML content.
I tried SmtpClient, but it doesn't show the mail, it sends it directly.
I tried Outlook interop, but I have the expected result only in debug, when I deploy the code server side I have the following message : "Retrieving the COM class factory for component with CLSID failed due to the following error: 80070005 Access is denied" (I installed Outlook both serverside and clientside).
And finally I tried .Process() with System.Diagnostics. This shows the mail before sending it, this fills it with a text, but I need the body to be formatted in HTML.
Anyone could help please ?
Thank you,
