Outlook not open encrypted email

    Question

  • Good afternoon. There is Exchange 2013 + Outlook 2010,2016. The user creates the certificate for enciphering of letters (on the basis of a template from corporate CA), adjusts it in Outlook. In case of receipt of the encoded letter the user can't open it, gives an error message that the certificate isn't found.

  • Hi,

    Does the issue happen to one specific user? In Outlook client, please go to File > Options > Trust Center > Trust Center Settings > E-mail Security, under Encrypted e-mail, click Settings. Make sure your certificate is configured correctly.

    If you are using the certificate for internal domain emails, please click Publish to GAL to have a try. If it doesn't work, please send a certificate-signed email firstly to the recipient, then let the recipient save your email address to his/her contact folder. Now you can send the encrypted email to this recipient, confirm if the issue persists.


    Regards,
