Let’s talk about something that might seem small but can cause some major headaches—managing attachments in Microsoft Outlook.

Whether you’re drowning in email attachments or wasting time searching for that one file you swore you saved, we’ve got you covered.

In this post, we’ll share 7 simple tips to help you master Outlook attachments and boost your productivity.

Please note:  NEVER open attachments unless you ABSOLUTELY KNOW they came from the person you expect them to come from.  When in doubt – CALL the person and ask if they sent you the attachment.  

Is Your Inbox Overflowing with Attachments?

If managing attachments is slowing you down, it’s time to get organized and save yourself from email overload! Let’s dive into these 7 pro tips for keeping your attachments under control.

1. Use OneDrive for Cloud Attachments

Instead of clogging up your inbox with large attachments, take advantage of OneDrive. When you attach files via OneDrive, you can send a link to the document rather than attaching the entire file. This not only saves space but also allows you to collaborate in real time—any updates made to the file are instantly available to everyone.  Depending on your comapny’s settings you may or may not be able to share from your OneDrive.  If you need assistance, reach out to DS Tech to check your permissions.

How to Do It:

  • Click Attach File > Browse Web Locations > OneDrive.

Stop Filling Up Your Inbox!

Using OneDrive for attachments keeps your inbox clutter-free and allows for seamless file collaboration.

2. Reduce File Sizes Before Sending

Large attachments can slow down your email and make it difficult for recipients to download or open them. To avoid this, compress your files or convert documents into smaller formats (like PDFs) before attaching them.  Lots of places may block .zip files by default for security so if this won’t work for you – skip it!

How to Compress Attachments:

  • Right-click the file and choose Send to Compressed (Zipped) Folder.

Make It Easy for Your Recipients

Don’t let large attachments be a barrier—compress files to ensure smooth delivery and quick access.

3. Take Advantage of Outlook’s Attachment Reminder

Have you ever forgotten to attach a file? Outlook has a built-in attachment reminder that scans your email for words like “attachment” or “attached” and prompts you if you forget to include the file. It’s a lifesaver for those “oops” moments.

How to Enable:

  • This feature is automatic, so you’ll get a reminder before hitting send if you forget to attach something.

Never Forget an Attachment Again!

Outlook’s attachment reminder is here to save you from embarrassing mistakes. Always double-check before hitting send.

4. Organize Attachments with Rules and Folders

If you receive frequent attachments, create rules in Outlook that automatically sort and organize your emails with attachments into designated folders. For example, you can create a rule to move all emails with PDF attachments into a specific folder.

How to Create a Rule:

  • Go to File > Manage Rules & Alerts > New Rule and follow the prompts to set up attachment-related rules.

Automation Is Your Best Friend

Stop sorting manually—let Outlook do the work for you by organizing attachments automatically.

5. Preview Attachments Before Downloading

Instead of downloading every attachment, you can preview files directly in Outlook. This feature is especially handy for quick document checks without cluttering your computer with unnecessary downloads.  Be careful not to click attachments unless they’re from a CERTAIN / KNOWN source.

How to Preview:

  • Simply click on the attachment in the reading pane, and Outlook will show a preview of the file.

Save Time with Quick Previews

Preview attachments without downloading to save time and reduce file clutter.

6. Convert Attachments to PDF for Easier Sharing

Sharing documents in PDF format ensures that the formatting stays consistent, and they’re easier for recipients to open. Plus, PDFs often have smaller file sizes, which reduces the chance of email delivery issues.

How to Convert to PDF:

  • Open your document, click Print >Choose Microsoft PDF > Save

Keep Your Files Consistent

Make sure your attachments look the same for everyone—convert to PDF before sharing.

7. Use Attachment Tools for File Cleanup

Outlook gives you the option to clean up old attachments from your emails. By using the Mail Attachment Remover tool, you can clear out large files that are taking up valuable inbox space without deleting the emails themselves.

How to Use:

  • Go to File > Tools > Mailbox Cleanup and use the cleanup tools to manage large attachments.
