How To Send A Large File On Outlook – Cloud Storage Link Solutions

by

Compressing files isn’t always enough when Outlook rejects your upload. Here is the correct method for sending large files without errors. You might have tried zipping a folder or reducing image sizes, only to see that dreaded “file too large” message. This guide will show you exactly How To Send A Large File On Outlook, step by step, using built-in tools and trusted third-party options. No more failed sends or frustrated recipients.

Why Outlook Blocks Large Files

Outlook has a default attachment size limit of 20 to 25 megabytes. This applies to both the desktop app and the web version. If your file exceeds this limit, Outlook will either refuse to attach it or fail during sending. The limit exists to protect email servers from overload and to keep messages moving quickly. But for large presentations, videos, or high-resolution images, this cap is a real problem.

Many users try to work around this by compressing files. While compression helps, it often isn’t enough. A 50 MB video might only shrink to 45 MB. You need a different approach. The good news is that Outlook offers several ways to bypass this limit without breaking any rules.

How To Send A Large File On Outlook

This section covers the most reliable methods. Each one works with Outlook 2016, 2019, 2021, and Microsoft 365. Choose the option that fits your file size and your comfort level with technology.

Method 1: Use OneDrive Or SharePoint Integration

If you have a Microsoft 365 subscription, this is the easiest method. Outlook can automatically upload large files to OneDrive and send a shareable link instead of the actual file. The recipient clicks the link to download or view the file. This method works for files up to 2 GB or more, depending on your plan.

  1. Open a new email in Outlook.
  2. Click the “Attach File” button in the ribbon.
  3. Select the large file from your computer.
  4. Outlook will detect the file size. If it’s too large, a prompt appears asking if you want to upload to OneDrive and share a link.
  5. Click “Share as OneDrive link” or “Upload to OneDrive.”
  6. Outlook uploads the file and inserts the link into the email body.
  7. Add your message and send normally.

The recipient does not need a Microsoft account to view the file. They just click the link. However, if you set permissions, they might need to sign in. You can adjust permissions by clicking the link settings before sending.

Setting Permissions For OneDrive Links

Before sending, you can control who can view or edit the file. Click the small “pencil” icon next to the link in the email. Choose “Anyone with the link” for open access, or “People in your organization” for restricted access. You can also set an expiration date or password for extra security.

Method 2: Use A File Compression Tool

If you prefer to send the file directly as an attachment, compression is still worth trying. But you need to use the right tool. Windows built-in “Send to Compressed (zipped) folder” works, but it doesn’t always reduce size enough. Try a dedicated compression tool like 7-Zip or WinRAR. These tools let you choose compression levels and split large files into smaller parts.

  1. Install 7-Zip (free) or WinRAR (trial).
  2. Right-click the file you want to send.
  3. Select “Add to archive” or “Add to [filename].zip.”
  4. In the compression settings, choose “Maximum” compression level.
  5. If the file is still too large, check the “Split to volumes” option and set a size like 10 MB or 20 MB.
  6. Click OK. The tool creates multiple smaller zip files.
  7. Attach each part to separate emails, or send them all in one email if the total size is under 25 MB.

Compression works best for text-heavy files like Word documents or spreadsheets. Videos and images compress poorly. For those, use the OneDrive method instead.

Method 3: Use A Third-Party File Transfer Service

If you don’t have OneDrive or SharePoint, third-party services are a good alternative. Services like WeTransfer, Dropbox, and Google Drive let you upload files and share links. You can then paste the link into your Outlook email. Most free plans allow files up to 2 GB.

  1. Go to a file transfer service like WeTransfer.com.
  2. Click “Add your files” and select the large file.
  3. Enter your email and the recipient’s email (if required).
  4. Click “Transfer” or “Upload.”
  5. Once uploaded, the service provides a download link.
  6. Copy the link and paste it into your Outlook email body.
  7. Add a short message and send.

Be aware that some services delete files after a few days. Check the expiration policy. Also, avoid sending sensitive information through free services unless they offer encryption. For business use, consider paid plans with better security.

Method 4: Split The File Using Windows Tools

If you don’t want to use cloud storage, you can split a large file into smaller pieces using a file splitter tool. Then attach each piece to a separate email. The recipient must combine the pieces on their end. This method is more technical but works offline.

  1. Download a free file splitter like GSplit or HJSplit.
  2. Open the tool and select the large file.
  3. Choose a split size, such as 10 MB per piece.
  4. Click “Split.” The tool creates several numbered files.
  5. Attach each piece to a separate email and send them one by one.
  6. Inform the recipient to use the same tool to combine the pieces.

This method is time-consuming and confusing for non-technical recipients. Use it only as a last resort.

Common Errors When Sending Large Files

Even with the right method, you might hit snags. Here are frequent issues and how to fix them.

Error: “File Too Large” Message

This usually means your attachment exceeds Outlook’s limit. Try the OneDrive method or compress the file. If you already tried compression, switch to a link-sharing method.

Error: OneDrive Upload Fails

Check your internet connection. Large files need stable upload speeds. Also, ensure you have enough OneDrive storage space. Free Microsoft accounts come with 5 GB. Paid plans offer more. Delete old files if needed.

Error: Recipient Cannot Open The Link

Make sure the link permissions are set correctly. If you chose “People in your organization,” external recipients cannot access it. Change to “Anyone with the link” for public access. Also, check if the link expired.

Best Practices For Sending Large Files

Follow these tips to avoid problems and keep your data safe.

  • Always compress files before attaching, even if you plan to use a link. Smaller files upload faster.
  • Use descriptive file names so recipients know what they are downloading.
  • Set expiration dates on shared links to prevent unauthorized access later.
  • Avoid sending sensitive files through free services. Use encrypted options like OneDrive with password protection.
  • Test the link yourself before sending. Open it in a private browser window to confirm it works.
  • Inform the recipient about the file size and method you used. They might need to install software or sign in.
