How To Email A File That Is Too Large Outlook : Large File Compression Techniques

by

Sending a file that is too large in Outlook can be solved by compressing it or using a cloud storage link instead. If you have ever tried to attach a video, a high-resolution image, or a large PDF to an email, you have likely seen the dreaded error message from Outlook. It usually says your file exceeds the size limit, which is typically 20 to 25 megabytes. This guide will show you exactly how to email a file that is too large outlook, using simple and effective methods.

You do not need to be a tech expert to fix this problem. There are several ways to get your large file to the recipient without any hassle. We will cover compression, cloud storage, and even some third-party tools. Each method is explained step by step so you can choose what works best for you.

Why Outlook Blocks Large Files

Outlook has a built-in size limit for attachments. This limit exists to keep email servers running smoothly and to prevent inboxes from getting overloaded. Most email providers, including Microsoft Exchange and Office 365, cap attachments at around 20 to 25 MB. If your file is bigger than that, Outlook will refuse to send it.

You might also run into issues if the recipient’s email server has a smaller limit. Even if your file is under 25 MB, it could still bounce back if the other side restricts attachments to 10 MB. Understanding these limits is the first step in learning how to email a file that is too large outlook.

How To Email A File That Is Too Large Outlook

This section covers the most practical solutions. Each method is easy to follow and does not require special software. Pick the one that fits your situation best.

Method 1: Compress The File Using Zip

Compressing a file reduces its size significantly. This is often the fastest way to send large documents or folders. Here is how to do it on Windows and Mac.

  1. Locate the file or folder you want to send.
  2. Right-click on it and select “Send to” then “Compressed (zipped) folder” on Windows.
  3. On a Mac, right-click and choose “Compress” from the menu.
  4. A new zip file will appear with a smaller size.
  5. Attach this zip file to your Outlook email.

Compression works best for text files, spreadsheets, and presentations. Images and videos may not shrink as much, but it is still worth trying. If the zip file is still too big, move to the next method.

Method 2: Use Cloud Storage Like OneDrive

OneDrive is integrated directly into Outlook. This makes it super simple to share large files without attaching them. You just upload the file to OneDrive and send a link.

  1. Open a new email in Outlook.
  2. Click on “Attach File” in the ribbon.
  3. Select “Browse This PC” or “Browse Cloud Locations.”
  4. Choose the file you want to share.
  5. If the file is too large, Outlook will automatically offer to upload it to OneDrive and share a link.
  6. Click “Share as OneDrive link” and send the email.

This method keeps your email lightweight. The recipient clicks the link to download the file. They do not need a OneDrive account to access it, but they might need to sign in if you set permissions.

Method 3: Use Google Drive Or Dropbox

If you prefer Google Drive or Dropbox, you can still share large files through Outlook. The process is similar to OneDrive. You upload the file to your cloud service and then paste the shareable link into the email.

  1. Upload your large file to Google Drive or Dropbox.
  2. Right-click the file and select “Share” or “Get link.”
  3. Set the sharing permissions to “Anyone with the link can view” or “edit.”
  4. Copy the link.
  5. Paste the link into your Outlook email body.

This method works for any file type. It also lets you control who can see the file. Just be careful with sensitive data, as public links can be shared further.

Method 4: Use A File Transfer Service

There are many free file transfer services online. Websites like WeTransfer, SendAnywhere, or Filemail let you send files up to 2 GB for free. You upload the file, enter the recipient’s email, and the service sends a download link.

  1. Go to a file transfer website like WeTransfer.
  2. Click “Add your files” and select the large file.
  3. Enter the recipient’s email address and your email.
  4. Write a short message if you want.
  5. Click “Transfer” or “Send.”
  6. The recipient gets an email with a download link.

These services are convenient, but they have expiration dates. Most links expire after a few days or a week. Make sure the recipient downloads the file quickly.

Method 5: Split The File Into Smaller Parts

If you cannot use cloud storage or compression, you can split the file into smaller chunks. This works for archives or large folders. You can use software like 7-Zip or WinRAR to split a file into multiple parts.

  1. Install 7-Zip or WinRAR on your computer.
  2. Right-click the file and choose “Add to archive.”
  3. In the options, look for “Split to volumes” or “Split into parts.”
  4. Set the size to 20 MB or less.
  5. Click OK to create multiple zip files.
  6. Attach each part to separate emails or send them all at once.

This method is a bit old-school, but it works. The recipient will need to combine the parts using the same software. It is not the most user-friendly option, but it is reliable.

Tips For Sending Large Files In Outlook

Here are some extra tips to make the process smoother. These will help you avoid common mistakes and ensure your file arrives safely.

  • Always check the file size before attaching. Right-click the file and select “Properties” to see the size.
  • If you use compression, let the recipient know they need to unzip the file.
  • For cloud links, set an expiration date if you want to limit access.
  • Test the link yourself before sending the email to make sure it works.
  • Consider using a password for sensitive files when using cloud storage.

These small steps can save you time and frustration. They also make you look more professional when sharing large files.

Common Mistakes To Avoid

People often make simple errors when trying to email large files. Here are the most common ones and how to avoid them.

  • Forgetting to compress the file before attaching. Always try zipping first.
  • Assuming the recipient has the same cloud service. Stick to popular ones like OneDrive or Google Drive.
  • Not checking the recipient’s email size limits. Some corporate email accounts have very low caps.
  • Sending multiple large attachments in one email. This can trigger spam filters.
  • Ignoring file type restrictions. Some email servers block executable files or archives.

Avoiding these mistakes will help your email go through without issues. If you are still stuck, the FAQ section below might help.
