Редактирайте MSG в Java

// Load the MSG file into Editor
Editor editor = new Editor("source.msg");

// Create and adjust the edit options
EmailEditOptions editOptions = new EmailEditOptions();

// Open input MSG document for edit — obtain an intermediate document, that can be edited
EditableDocument beforeEdit = editor.edit(editOptions);

// Grab MSG document content and associated resources from editable document
string content = beforeEdit.getEmbeddedHtml();

// Send the content to WYSIWYG-editor, edit it there, and send edited content back to the server-side
// This step simulates a such operation
string updatedContent = content.replace("project", "Edited project");

// Grab edited content and resources from WYSIWYG-editor and create a new EditableDocument instance from it
EditableDocument afterEdit = EditableDocument.fromMarkup(updatedContent, null);

// Create a save options
EmailSaveOptions saveOptions = new EmailSaveOptions();

// Save edited MSG document to the file
editor.save(afterEdit, "edited.msg", saveOptions);
