Can I view the full content of an email, including attachments, without using a SOAP API call?

Yes. After obtaining the Item ID, you can retrieve the complete email content by accessing a fixed URL: `https://<server>/service/home/~/?auth=co&view=text&id=<ItemID>`. The response includes the email body and any Base64-encoded attachments. This method is detailed in the Zimbra SOAP API Development Guide 3 - Email Operations and is useful for export tasks described in Zimbra SOAP API Development Guide 4 - Email Export and Folder Sharing.
