Hi,

We bought ‘UltimateMail - With Source Code’.

Now I’m testing the code that’s used in the workflow running under Local System account. I have the following situation (connecting with IMAP):

1.       If I send a message signed with a Comodo certificate, the code shows that the email is signed. That’s perfect. Outlook 2013 shows the same result.

2.       If I send a message signed with a certificate released by Enterprise CA in Active Directory, the code shows that a message is NOT signed. Outlook 2013 shows the signed email.

3.       If I send a message that signed and encrypted with Comodo certificate, the code shows that the email is NOT signed but encrypted. Outlook 2013 shows the signed and encrypted email.

4.       If I send a message that signed and encrypted with a certificate released by Enterprise CA in Active Directory, the code shows that the email is not signed but encrypted. Outlook 2013 shows the signed and encrypted email.

For the case 3 and 4 the message is IsEncrypted == true not Decryptable but it could be related to the fact that the code runs under Local System account. The certificate is installed in tthe Local computer Certificates -> Personal->Certificates and has a private key.

How can I make the code (copied from your help 'as is') decrypt emails if the code is running under System account?

And how to make the code sees that signed and encrypted email is not only encrypted but also signed?
