This problem may indicate an underlying problem on your PC or with your account. Let’s find out what the problem can be. 

Why Can’t I See Attachments in Outlook App for Windows 10?

If your Outlook Web App has problems downloading attachments, the issue can be caused either by the browser you’re running the Outlook Web app, your account, or Outlook’s own functionality.

Here are some of the associated problems:

  • Browser compatibility issues. This is common with Google Chrome. 
  • Poor Internet or low Internet bandwidth.
  • Conflicting cache, cookies, or user data. This can interfere with or break the Outlook Web App’s functionality.
  • Restriction or conflict with security software.
  • Unsupported file attachment extension or document.
  • Suspicious attachment sender.
  • Blocked attachment extensions.
  • Incompatible browser add-on or extensions that conflict with Outlook on the web.
  • New or updated user interface: A recent feature change triggers an HTTP 302 redirect to a static Office 365 URL. This causes the Outlook attachment error. It often occurs if you’ve opened an additional mailbox in OWA and then you try to download or preview an attachment.

Security Note: Outlook accepts a wide variety of file types, but will block potentially unsafe attachments (including .bat, .exe, .vbs, and .js files) whose files can contain malware/viruses. Even with Outlook attachment protection, always be careful when opening any attachment, especially if it’s from someone you don’t know or trust. Confirm the attachment's authenticity with the sender if you're in doubt. Also, keep your computer antivirus software open and always up to date.

How to Resolve the Unable to Download Attachments from Outlook Web App Issue

If you can’t download attachments from your Outlook Web App, first check if you have stable Internet bandwidth. Low bandwidth or unstable Internet can cause error. 

Also, check and confirm that the file is from a trusted sender. If Outlook doesn’t trust the sender for any reason, it will block the attachment’s preview or download. This might be the reason you can’t preview or download the file. 

Besides, the issue might be on the Outlook Server and not your account or browser. So, check if the issue is on the server side. You can try downloading the file from another computer or another network to see if the error persists. If it persists, then it might be on the server. 

Also, log out from Outlook and then, re-login and, enter your details, then try to download the file. If the problem was because of any bugs, this solution should solve it.

Check and make sure the attachment has a supported file extension. Outlook Web App blocks file extensions that your PC doesn’t support.

How to Fix Outlook Web App Cannot Download Attachments

If you cannot download your files after these solutions, proceed to the solutions below.

1] Download File as a ZIP File

If the email has more than one file attachment, Outlook Web can compress all files into a single ZIP file and allows you to download it as a ZIP file. You can download the ZIP file using the following steps:

  1. Launch your browser. 
  2. Launch the Outlook Web App from the browser and sign in to your account using your credentials.
  3. Open the email with the multiple file attachments you want to download.
  4. In the location of the attachments, select Download All.
    outlook web app mail

  5. If you’ve not already set the download location, you will use the browser’s Save dialog box to choose the location and then save the ZIP file. 

The email's subject will be the ZIP file's default name. You can replace the name if you want to give the file a different name.

2] Run Outlook Web App on a Different Browser

Some web browsers have compatibility issues with Outlook on the web and may prevent some of its features and functionalities. So, if you are unable to download attachments from Outlook Web App, try running on a different web browser and see if the issue goes away. 

In addition, since the issue can also be caused by corrupt cache and cookie files, running Outlook Web App on a different browser can help isolate the issue. 

3] Clear the Cache and Cookies

Depending on your browser, you can consider clearing the browser’s cache and cookies.

If you’re using Chrome, use the following steps to clear cache and cookies:

  1. On your computer, launch Chrome.
  2. At the top right, click More (the three vertical dots on the top right).
  3. Next, click More tools and then click Clear browsing data on the context menu.
  4. At the top dialog box, choose a time range within which you want to delete the data. To delete everything, just select All time.
  5. Now, check the checkboxes next to “Cookies and other site data” and “Cached images and files”.
  6. Finally, click Clear data and all your cookies and cache will be deleted.

If you use Microsoft Edge, here are the steps to clear delete cookies:

  1. Launch your Microsoft Edge.
  2. Select Settings and more (three horizontal dots).
  3. Select Settings (the gear-shaped icon).
  4. Now, select Privacy and services.
  5. Under the section of Clear browsing data, select Choose what to clear.
  6. Under the Time range dialog box, choose a time range.
  7. Next, select Cookies and other site data, then select Clear now.

If you are using Safari or another browser, you can check their support site for instructions for deleting their browser cookies and cache.

Once you’re done deleting cookies and cache, launch Outlook Web App and see if you can now download the attachments.

4] Disable Chrome’s Safe Browsing 

If you’re using Chrome to access Outlook Web App, you should know about possible issues such as safe browsing, ad blocking, flagging settings, etc. These Chrome features may not be compatible with Outlook Web App. You can consider removing or disabling them to allow you to use OWA without any issue,

  1. Launch Google Chrome.
  2. In the browser's search bar, type in chrome://settings/

  4. Next, locate the Safe Browsing (Protects you and your device from dangerous sites) option.
  5. Toggle it off using the toggle button.

5]  Save Attachments on OneDrive

Outlook allows users of the Outlook Web App to save attachments directly to OneDrive. But this is limited to OneDrive for Business. When you save files to the OneDrive app, they’re added to the email attachments section in OneDrive for Business. 

You can choose the “Save to OneDrive” option to access the files from there. 

Here’s what to do:

  1. In Outlook Web App, open the email with the attachments you cannot download.
  2. Click on the dropdown menu next to the attachment.
  3. Now, select and click on “Save to OneDrive”.
  4. If there's more than one attachment that can’t open, click on “Save all to OneDrive”.
  5. Once you’ve added a file to OneDrive for Business, you should see a confirmation message “Saved to Email attachments.”

Now, you can access the files from the Email attachments in OneDrive.

6] Enable Attachment Preview

Here’s how to unblock attachments in Outlook Web App:

  1. Launch your browser and launch the Outlook Web App.
  2. Click “Settings” (the Gear icon).
  3. Select “Options”.
  4. Next, click on “Active view settings”.
  5. Now, select “Always show previews” (for instance, photos and videos).
  6. Save the changes.

Note: This option works well, especially with photo and video attachments on the Outlook Web App.

7] Use Outlook Web App Light Version

If you are using a low bandwidth Internet connection or an older web browser, you can use the light version of Outlook Web App to solve your attachment download needs. 

Here’s how to access the Outlook Web App light version: 

  1. On your Outlook Web App, click “Settings” (the gear icon on the upper right corner).
  2. Click on “Mail”.
  3. Select and click on “General”.
  4. Check the box next to the “Use the Light version of Outlook Web App” option.

Alternatively, you can go to the Outlook Web App Light Version Page here:

Once you’re there, sign in to your account and check if you can download the attachments.

8] Use the Old Outlook Web App User Interface

The updated version of the Outlook Web App has some amazing features. But these add-ons come with functionality issues, glitches and make the application heavy. This might be the reason the “unable to download attachments” issue is common among users.

If this is the case, you can revert to the application’s old user interface, sign in to your account and see if you can download the attachments. Here’s what to do:

  1. Launch your web browser.
  2. Now on the search bar, search the old Outlook Web App (you can copy and paste this URL:
