Hello,

There's no built-in option for exporting as PDF to a network location, but you can use an SDK Script activity within Workflow to some document types to PDF, and PDF/A is one of the options.

It would look something like this

                    // Build a list of watermarks and add tag watermarks associated with the document
                    List<WatermarkSpecification> watermarks = new List<WatermarkSpecification>();
                    foreach(TagWatermark w in doc.GetTagWatermarks()){
                        watermarks.Add(new WatermarkSpecification(w.WatermarkText,w.WatermarkTextSize,w.WatermarkRotation,w.WatermarkPosition,String.Empty,0,String.Empty,0,w.WatermarkIntensity));
                    }

                    // Initialize document exporter
                    DocumentExporter dExp = new DocumentExporter();

                    // Configure document exporter settings
                    dExp.CompressionQuality = compression;
                    dExp.IncludeAnnotations = true;
                    dExp.BlackoutRedactions = true;
                    dExp.PageFormat = DocumentPageFormat.Jpeg;
                    dExp.Watermarks = watermarks;

                    // Set PDF export options to flatten annotations and include searchable text
                    PdfExportOptions ExportOptions = PdfExportOptions.RenderAnnotationsAsImage | PdfExportOptions.IncludeText | PdfExportOptions.PdfAConformance;

                    // Export PDF
                    dExp.ExportPdf(doc, doc.AllPages, ExportOptions, file);

Note the PdfExportOptions.PdfAConformance option being set for the ExportOptions.
