How do I send a MIME attachment in Outlook?

Answered by Randy McIntyre

To send a MIME attachment in Outlook, follow these steps:

1. Create a new email message by clicking on the “New Email” button or pressing Ctrl+N.
2. Once the email message is open, go to the Mimecast tab at the top of the Outlook window. If you don’t see the Mimecast tab, make sure you have the Mimecast for Outlook add-in installed and enabled.
3. In the Mimecast tab, locate and click on the “Attach Large Files” icon. This will open the Large File Send window.
4. In the Large File Send window, you can select the files you want to attach by clicking on the “Add Files” button. This will open the file explorer, allowing you to browse and select the desired files from your computer.
5. After selecting the files, click on the “Send” button to attach them to the email message. The files will be uploaded to the Mimecast cloud storage, ensuring that they can be easily sent without any size limitations.
6. If needed, you can amend the Large File Send options by clicking on the “Options” button in the Large File Send window. This will allow you to customize settings such as expiration dates, notifications, and password protection for the attachments.
7. Once you have reviewed your email message and attachments, click on the “Send” button in the Outlook ribbon to send the email with the MIME attachments.

It’s important to note that using Mimecast’s Large File Send feature allows you to send files larger than the typical attachment size limit imposed by email providers. This is especially useful when dealing with large files or multiple files that would exceed the maximum attachment size.

I personally find the Large File Send feature in Mimecast to be extremely helpful in my daily work routine. I often need to send large files to clients or colleagues, and being able to do so directly from Outlook without worrying about file size limitations is a great convenience.

Additionally, Mimecast offers various options to customize the Large File Send feature based on specific requirements. For example, you can set an expiration date for the attachments, after which they will no longer be accessible to the recipient. This ensures that your files remain secure and are not accessible indefinitely.

Sending MIME attachments in Outlook using Mimecast’s Large File Send feature is a simple and effective way to overcome attachment size limitations. By following the steps outlined above, you can easily attach and send large files without any hassle.
