EWS managed api : Is there a way to identify if an email or attachment is encrypted?


Does EWS managed api expose any property to identify whether an item( email/attachment) is encrypted?


var isEmailOpaqueSignedOrEncrypted = false; if (email.ItemClass == "IPM.Note.SMIME") { var attList = email.Attachments.ToList(); if (attList.Count == 1) { isEmailOpaqueSignedOrEncrypted = true; } };
