If you’re experiencing trouble with attachments not downloading in Outlook, you’re not alone. This issue can prevent you from accessing important files sent via email, causing frustration and delays. Fortunately, most problems are fixable with some straightforward troubleshooting steps. This guide will walk you through how to resolve attachment download issues in Outlook, whether you’re using the desktop app or Outlook on the web. Before starting, ensure your internet connection is stable, as a poor connection can interfere with downloads. Also, check if your Outlook is up to date, since outdated software can cause compatibility issues.
What You’ll Need
- Stable internet connection
- Access to your Outlook account (email and password)
- Optional: Administrator rights on your device (for some settings changes)
Step-by-Step
- Check Your Internet Connection: Ensure you are connected to a reliable network. Try opening a webpage or streaming a video to confirm connectivity.
- Update Outlook: Open Outlook and go to File > Office Account > Update Options > Update Now. Installing the latest updates can fix bugs that cause download issues.
- Disable Add-ins Temporarily: Sometimes, add-ins interfere with email functions. Go to File > Options > Add-ins. At the bottom, select COM Add-ins and click Go. Uncheck all add-ins, then restart Outlook and try downloading attachments again.
- Check Attachment Settings: In Outlook, go to File > Options > Trust Center > Trust Center Settings > Attachment Handling. Ensure that the setting “Turn off Attachment Preview” is unchecked, and that attachments are set to download automatically.
- Clear Outlook Cache: Close Outlook. Navigate to %localappdata%
Microsoft or Outlook. Delete the contents of the Cache folder. Restart Outlook and attempt to download attachments again. - Adjust Security Settings: Sometimes, security software blocks downloads. Temporarily disable your antivirus or firewall and test if attachments download. If they do, add Outlook to your software’s exception list.
- Use Outlook Web Access: If the desktop app fails, try accessing your email via Outlook on the web at outlook.live.com or your organization’s webmail portal. Download attachments directly from there to determine if the issue is local or server-side.
- Check Storage Space: Ensure your device has enough free storage space. Lack of space can prevent files from downloading properly.
- Reset Outlook Profile: If issues persist, create a new Outlook profile. Go to Control Panel > Mail > Show Profiles > Add. Set up your email account again and test attachment downloads.
Common Mistakes
- Ignoring software updates — outdated versions can cause bugs.
- Disabling security software permanently — this can expose your device to threats.
- Attempting to open attachments in unsupported formats — ensure you have the correct applications installed.
- Not checking internet connectivity — unstable connections are a common cause of download failures.
- Overlooking storage space — insufficient space prevents files from saving.
Tips
- Always keep Outlook and your device’s OS updated to benefit from bug fixes and security patches.
- Use the Outlook web app as a quick alternative if desktop issues persist.
- Regularly clear cache and temporary files to improve Outlook performance.
- Scan your device for malware if you suspect security software is blocking downloads.
- Contact your IT department if you’re in a corporate environment for server-side issues.

- Restart your device to clear temporary glitches.

- Check your email server status—outages can prevent attachment downloads.
