Problem with email sent with PGP encryption - plain text / tnef

    Question


  • I have a small problem when sending email signed and encrypted with PGP, all recipients receive a att.00001 with nothing inside  and att00002.bin file that when opened with notepad shows the -----BEGIN PGP MESSAGE-----. Exchange just refuses to send in plain text format. TNEF enable is set to false, aslo I try and do disable, delete and recreate Front end connector , disabled all exchange spam filters. doesn't matter if the receiver uses Exchange or not , the email is delivered in the same way with attachments

    When email is sent in clear with no encryption, it behaves just fine 

    Using winserver2012 + Exchange 2013 + Blackberry Enterprise 12.

    I have no more ideas.

  • Hi,

    Since this issue only occur if enable PGP encrypt, I recommend check the configuration in PGP server.

    However, I not familiar with it and don't provide from Microsoft, I recommend contact application provider for further assistance.
