Removing Specific Attachments from an Email

Overview

Learn how to remove attachments with a particular name and file type (DOCX) from an email. This feature helps declutter emails by eliminating unnecessary DOCX files programmatically.

Step 1: Define Input and Output Paths

Set up paths for your input email file and output directory:

string documentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "InMessage.msg"); // Replace with your actual file name.
string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Ensure this directory exists or create it before running the code.
string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));

Step 2: Initialize Email Load Options

Load your email using GroupDocs.Watermark’s Watermarker class with specific load options:

var loadOptions = new EmailLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Further processing will be done here.
}

Step 3: Retrieve and Iterate Over Attachments

Access the email’s attachments and iterate over them in reverse order to safely remove items:

EmailContent content = watermarker.GetContent<EmailContent>();

for (int i = content.Attachments.Count - 1; i >= 0; i--)
{
    EmailAttachment attachment = content.Attachments[i];
    
    // Check if the attachment name contains 'sample' and is of DOCX file type
    if (attachment.Name.Contains("sample") && attachment.GetDocumentInfo().FileType == FileType.DOCX)
    {
        // Remove the attachment from the email
        content.Attachments.RemoveAt(i);
    }
}

Step 4: Save the Modified Email

Save the modified email to your specified output path:

watermarker.Save(outputFileName);

Troubleshooting Tips

  • Ensure that YOUR_DOCUMENT_DIRECTORY and YOUR_OUTPUT_DIRECTORY paths are correctly set.
  • Verify file types of attachments before attempting to remove them to avoid runtime errors.

Practical Applications

Removing specific attachments from emails is beneficial in various scenarios:

  1. Automated Email Management: Streamline email processing workflows by programmatically filtering out unwanted DOCX files.
  2. Data Privacy Compliance: Remove sensitive documents that should not be shared or stored.
  3. Email Archiving: Simplify the archiving process by excluding large attachments.

These use cases can also integrate with other systems like CRM software to enhance data management processes.
