How to email a zip file in outlook

Last Updated: Mar 8, 2024 by

Email attachments are a convenient way to share files with others, but sometimes the file size can be too large to send as a regular attachment. In these cases, zipping the file can help reduce the size and make it easier to send. If you use Microsoft Outlook as your email client, here’s a step-by-step guide on how to email a zip file in Outlook.

Compressing the File

Before you can email a zip file in Outlook, you need to compress the file into a zip format. This can be done using a variety of programs, such as WinZip, 7-Zip, or the built-in compression tool on your computer. Once the file is compressed, it will have a .zip extension at the end of the file name.

Attaching the Zip File

Open Outlook and create a new email. Click on the “Attach File” button, which is usually located in the top menu bar. A window will pop up, allowing you to browse your computer for the zip file you want to attach. Select the file and click “Open.” The file will now be attached to your email.

Sending the Email

Before sending the email, it’s important to check the file size of the zip file. If it’s still too large, you may need to compress it further or use a file sharing service instead. If the file size is acceptable, you can now send the email as you normally would. The recipient will receive the email with the zip file attached.

Tips for Emailing Zip Files

  • It’s important to note that some email providers may have a limit on the size of attachments they allow. If your zip file is too large, you may need to use a file sharing service instead.
  • When sending a zip file, it’s a good idea to include a brief explanation of what the file contains in the body of the email. This will help the recipient understand the purpose of the file and ensure they open it.
  • If you are sending a zip file to someone who is not familiar with zip files, you may want to include instructions on how to unzip the file. This can be done by right-clicking on the file and selecting “Extract All.”


If you encounter any issues while trying to email a zip file in Outlook, here are a few troubleshooting tips:

  • Make sure the file is properly compressed and has a .zip extension.
  • Check the file size to ensure it is within the limits of your email provider.
  • If the recipient is having trouble opening the zip file, make sure they have a program that can unzip files installed on their computer.


Emailing zip files in Outlook is a simple process that can help you share large files with others. By following these steps and tips, you can easily send zip files through email without any hassle. Have you tried emailing zip files in Outlook before? Let us know in the comments.
