Hi. I made a SMTP client for sending emails and i encrypt and sign emails with Smime methods Encrypt() and Sign(). When I receive the email I cannot open it in Outlook 2007, but in Outlook 2003 it works fine. I have instaled the proper certificates, I tried to use the latest Mailbee.NET component , but it still doesn't work. When I try to open it I get the error message: "Security system couldn't find the name of your digital ID"(the same I get when I don't have the certificate)

Are you running both Outlook 2007 and Outlook 2003 on the same machine or on different ones? If those are different machines, check Internet Explorer options on the machine with Outlook 2007 and make sure certificate with your private key is there under Personal tab of Certificates store.

They are running on different machines.
I checked the certificate store and the certificate is under Personal tab.
Any other ideas?

Do you see the following text when viewing the certificate?
Quote:
You have a private key that corresponds to this certificate

And if you sign a message with that certificate and send the message from the machine with Outlook 2003 to the machine where Outlook 2007 is installed, does everything work as expected or error occures as well?

Even if sent not from MailBee, e.g. if sent from Outlook 2003? It should be addressed to Microsoft in that case.

Sorry if my previous question was not clear enough, I meant trying to sign & send from Outlook 2003 and receive by Outlook 2007.

Try to decrypt and verify the message with MailBee.NET on the machine with Outlook 2007 installed. Does it work?

Hi. I tried to decrypt and verify the message on machine with Outlook 2007 and it worked(I got the original message). But in outlook 2007 on the same machine I couldn`t open the email(same error message I got before). The certificate was installed correctly and in correct cert. store.

We've tried reproducing the issue with Outlook 2007, and everything worked as expected. The only suggestion we have at the moment is to check the certificate placed in the store and make sure it contains the same email address in "E" line as the one messages are sent to.

Hi. I checked the "E" line, but in Outlook 2003 it works fine even if the sender's email is diferent from "E" param in certificate. In Outlook 2007 we used open the emails from email in "E" param and from it's alias but it didn't help(today I tried it on 2 computers). Can you check my code, if it works for you? Thanks.

My Settings:
MailBee.NET version 5.8.2.173 or 3.0.2.79
.NET framework version 3.5 SP1
Visual Studio version 9.0.30729.1
Outlook 2003 version 11.8313.8221 SP3
Outlook 2007 version 12

And Code:

Smtp.LicenseKey = "";
                MailBee.Security.Powerup.Licen seKey = "";
                Smtp objMailBeeSMTP = new Smtp();
                objMailBeeSMTP.SmtpServers.Add (new SmtpServer("smtpserver",25,1));
                MailBee.Mime.MailMessage msg = new MailBee.Mime.MailMessage();
                msg.BodyPlainText = "ahoj";
                msg.Subject = "mailbee mail test";
                msg.From = new MailBee.Mime.EmailAddress("mail");
                msg.To.Add(new MailBee.Mime.EmailAddress("mail"));
                msg.Attachments.Add(@"path", "file1.txt", "");
                Smime smime = new Smime();
                CertificateCollection coll = new CertificateCollection();
                Certificate encr = new Certificate(@"path", CertFileType.Cer, "");
                Certificate sign = new Certificate(@"path", CertFileType.Pfx, "");
                coll.Add(encr);  &nb sp;         &nb sp;  
                msg = smime.SignAndEncrypt(msg, sign, coll);                
                objMailBeeSMTP.Message = msg;
                objMailBeeSMTP.Send();
