In this article, we’ll explore common issues and provide helpful solutions to ensure a seamless experience with attachments in Outlook Web App. So grab your coffee and let’s dive in!

Outlook Web App Attachment Download Issues in Google Chrome

Attachments are an essential part of communication in the digital era. However, some users have reported difficulties downloading attachments in Outlook Web App, particularly when using Google Chrome as their browser.

If you’re facing this issue, fear not – we have some tips to help you out!

One possible reason for the problem is that Google Chrome’s built-in security features may interfere with the download process. To resolve this, try disabling Chrome’s safe browsing features temporarily.

Here’s how:

1. Open Google Chrome and click on the three vertical dots at the top-right corner to access the browser’s menu.

2. Select “Settings” from the dropdown menu.

3. Scroll down and click on “Advanced” to expand additional settings.

4. Under the “Privacy and security” section, disable the “Safe Browsing” feature.

5. Restart your browser and try downloading the attachment again.

If disabling Chrome’s safe browsing features doesn’t work, you can also try whitelisting the sender and allowing specific file types. To do this:


Open Google Chrome and navigate to the “Settings” page as explained above. 2.

Scroll down to find the “Privacy and security” section. 3.

Click on “Site Settings” to access more options. 4.

Locate and click on “Content settings.”

5. Scroll down to the “Automatic downloads” section and click on “Additional content settings.”


Under the “Automatic downloads” section, click on “Add” to add a new rule. 7.

Enter the email address of the sender in the “Hostname pattern” field. 8.

Choose “Allow” from the “Behavior” dropdown menu. 9.

Click on “Add” and repeat the process for other trusted senders. 10.

Restart your browser and try downloading the attachment again.

Outlook Web App Attachment Preview and Safe Browsing Features

While downloading attachments may sometimes be challenging, Outlook Web App offers a useful feature that allows you to preview attachments without downloading them to your computer. This can help you decide if it’s safe to open the file or if you need to take additional precautions.

However, keep in mind that the preview feature also relies on the safe browsing features of your browser. To ensure a smooth experience, you can take the following steps:


Follow the steps mentioned above to access Google Chrome’s “Settings” page. 2.

Scroll down to the “Privacy and security” section and click on “Site Settings.”

3. Under the “Permissions” section, click on “Additional content settings.”


Look for the “PDF documents” or “Untrusted file types” subsection and make sure it is set to “Ask first” or “Open PDF files in the default PDF viewer.”

5. If necessary, click on “Add” to add additional file types that you want to preview.

6. Restart your browser for the changes to take effect.

By whitelisting trusted senders and allowing specific file types, you can enhance your attachment previewing experience while maintaining a secure browsing environment. Now that we’ve covered attachment download issues in Google Chrome and explored attachment preview features, let’s move on to another set of common problems and their solutions.

Outlook Web App Attachment Download Error for XML Files

XML files are commonly used for data exchange purposes, but sometimes they fail to download properly in Outlook Web App. If you’re encountering an attachment download error specifically for XML files, don’t worry – we have a solution just for you.

The issue might stem from the mailbox policy set by your organization. Some mailbox policies restrict the download of certain file types for security reasons.

To resolve this problem, you may need to consult with your IT department or someone with administrative access to your Outlook Web App. They can help modify the mailbox policy to allow XML file downloads.

Changing Mailbox Policy Using PowerShell to Allow Permitted Extensions

If you have administrative access to your Outlook Web App or you’re an IT professional, you can change the mailbox policy using PowerShell to permit specific file extensions. This ensures that users can download attachments without encountering any unnecessary errors.

Here’s a step-by-step guide:

1. Open PowerShell with administrative privileges.

2. Run the following command to connect to Exchange Online:





Enter your Office 365 Global Administrator credentials when prompted. 4.

Run the following command to check the current mailbox policy:




5. Identify the policy you want to modify and note down its name.

6. Run the following command to change the allowed file extensions for the desired policy (replace “PolicyName” with the name you noted down earlier):


Set-OwaMailboxPolicy -Identity PolicyName -AllowedFileTypes ‘.docx’,’.xlsx’,’.pdf’,’.jpg’


Modify the list of allowed file extensions as required.

7. Confirm the changes by running the following command:


Get-OwaMailboxPolicy | fl Identity,AllowedFileTypes


This command displays the updated policy and its allowed file extensions.

8. Close PowerShell.

By following these steps, you can modify the mailbox policy and permit specific file extensions, ensuring a smoother attachment download experience for your organization’s users. That wraps up our exploration of attachment issues in Outlook Web App.
