    RE: Cannot delete attachement from draft email !!

    Yes i work with this plugin since Junuary 2017, i think the problem is after to installation of SP1 (dynamics 365)

    this is the code :

     private static void CreateActivityMimeAttachement(IOrganizationService service, EntityReference sourceEmail, string filename, string documentBody)

           {

               Entity ResultEntity = service.Retrieve("email", sourceEmail.Id, new ColumnSet(true));

               Entity ActivityMimeAttachement = new Entity("activitymimeattachment");

               ActivityMimeAttachement["objectid"] = new EntityReference("email", ResultEntity.Id);

               ActivityMimeAttachement["objecttypecode"] = "email";

               ActivityMimeAttachement["filename"] = filename;

               ActivityMimeAttachement["body"] = documentBody;

               ActivityMimeAttachement["mimetype"] = @"application/pdf";

               service.Create(ActivityMimeAttachement);

           }

    Can you include the code for CreateActivityMimeAttachement? I've added all the same functionality (minus the PDF part) in Workflow Elements so I can check your code against that.

    Have you verified the pdf is generating correctly on your server?

    RE: Cannot delete attachement from draft email !!

    Hi the scenario is  : in the opportunity entity i generate a word document and i saved it in the annotation of opportunity

    and i added a Dialogue, in this dialog i choose the document word to add to the  email ( email created in the dialog)  and i convert it to pdf and add it to an email, i use workflow ith CodeActivity

    this a part of my code( it work fine since i passed to crm 2016 to Dynamics 365)

    private static void ConvertToPDFandAttachToEmail(IOrganizationService service, EntityReference email, string filename, string documentBody, Guid guidNote)

           {

               if (!string.IsNullOrEmpty(filename))

               {

                   //Create temporary folder to stock word and pdf doc

                   Guid folderName = Guid.NewGuid();

                   string folderPath = Properties.Settings.Default.UrlTempFolder + folderName.ToString() + "\\";

                   string fileWord = folderPath + filename;

                   bool exists = System.IO.Directory.Exists(folderPath);

                   if (!exists)

                       System.IO.Directory.CreateDirectory(folderPath);

                   string fileNameWithOutExtension = Path.GetFileNameWithoutExtension(fileWord);

                   string fileExtension = Path.GetExtension(fileWord);

                   if (fileExtension.Equals(".doc") || fileExtension.Equals(".docx"))

                   {

                      //download the word doc frm crm and stock it to tomporary folder

                       using (FileStream fileStream = new FileStream(folderPath + filename, FileMode.OpenOrCreate))

                       {

                           byte[] fileContent = Convert.FromBase64String(documentBody);

                           fileStream.Write(fileContent, 0, fileContent.Length);

                           fileStream.Close();

                           //Convert doc word to pdf                  

                           string FileToJoindre = Path.ChangeExtension(folderPath + fileNameWithOutExtension, "pdf");

                         //this is methode call and externe service

                           convertToPDF(fileWord, FileToJoindre);

                           byte[] fileContentPDF = File.ReadAllBytes(FileToJoindre);

                           string fileBodyContent = Convert.ToBase64String(fileContentPDF);

                           string newFileName = Path.GetFileName(FileToJoindre);

                           //Joindre doc to email

                           CreateActivityMimeAttachement(service, email, newFileName, fileBodyContent);

                       }

                   }

                   else

                   {

                       //Create attachement without  convert to pdf if its not a word doc

                       CreateActivityMimeAttachement(service, email, filename, documentBody);

                   }

                   //delete folder contains word and pdf doc

                   Directory.Delete(folderPath, true);

               }

           }

    RE: Cannot delete attachement from draft email !!

    Hi Soy,

    When you say a plugin, are you referring to a Workflow or an actual Plugin? I didn't think there was a message to generate the word templates in the plugins.

    Given you scenario, the most likely cause is the code which is attaching the template to the email. If you have that code, could you share it and I can tell you what might be wrong?

    Thanks,

     Aiden

    Hi Soy,

    The null reference exception looks like it's coming from Dynamics itself, not any code you're running (I only see MSFT in the stack trace but may have missed it). Are you on prem or online? How are the attachments being included in your email messages?

    Thanks,

     Aiden
