If you don't know how to send large files through Outlook, this article will help you. It includes many methods and tips to send large files in Outlook quickly and securely.

Part 1: How To Send Large Files in Outlook With Smart Solutions

Sending large files through Outlook can be difficult due to the size limitations of the attachments. With a maximum attachment limit of 20MB, it can be hard to send large files using Outlook. Below we have selected three easy solutions for you to send big files in Outlook:

Solution 1: Zip File Before Sending

The first method is to try and ZIP the file using reputable software. ZIP is a file format commonly used for compression and archiving. When you ZIP one or more files, the files are compressed into a single archive file with a zip extension. Since it reduces the size of files, it might take your file under 20MB. Here is how to zip and send large files using Outlook:

Step 1: Download and install ZIP software like WinRAR or 7-Zip on your computer and navigate to the file you want to send. Select all the files, right click and choose "Add to Archive."

While using the ZIP format for compressing the files helps reduce their sizes, it doesn't always work. Especially in the case of high-quality files like videos, it rarely makes a significant size reduction. Thus, you would need to compress such files using other techniques. To elaborate, ZIP files are compressed, but not all compressed files have ZIP format. Use the following steps for how to send large files via Outlook:
