Hello, for several users we have a problem with the fact that Cleopatra in Outlook starts reporting to them the message: "Can t encrypt/sign an empty massage." Outlook has the latest version.
They use version 4.2.0 and 4.0.0, Emails are hosted on exchange online. It does this for all encrypted messages we want to send.
Can you please help us solve this problem?
Thank you.
Daniel
