Microsoft Outlook had problems encrypting


  • Hello all.

    We configure s/mime in our lan we can sign mail but if we will try to encrypt an email
    we receive the following error. The error appears to internal users, using outlook 2007.

    Microsoft Outlook had problems encrypting this message because the following recipients had missing or invalid certificates, or conflicting or unsupported encryption capabilities

    You receive an error message when you try to send an encrypted e-mail message to another user who is in the same Exchange organization in Outlook
