Symptoms

When you try to preview an Office file attachment in the Microsoft Outlook reading pane, you receive the following error message:

This file cannot be previewed because of an error with the following previewer

Cause

This problem occurs if both of the following conditions are true.

• Windows Firewall service is not running.
• You're using Outlook on a Windows 10, Windows 8.1, Windows 8, or Windows Server 2012-based computer.

Resolution

To resolve this issue, start the Windows Firewall service:

1. Press the Windows key+R (to open the Run dialog box).
2. Type services.msc, and then select OK.
3. In the Services window, right-click Windows Firewall, and then select Properties.
4. Make sure that the Startup type is set to Automatic, and then select OK.
5. Right-click Windows Firewall, and then select Start.

More information

The Previewer feature in Outlook uses the Protected View feature (also known as a sandbox). This feature was introduced in Microsoft Office 2010. In Windows 10, Windows 8.1, Windows 8, and Windows Server 2012, the Protected View feature has been improved in conjunction with the AppContainer feature. This provides stronger process isolation, and it also blocks network access from the sandbox.

The Disconnect Chrome extension causes this. The easiest is to disable it for Gmail (the same goes for Inbox).

Just click og the disconnect plugin next to the address bar and the click on Whitelist site. This reloads Gmail and the attachment should now be available. After clicking Whitelist site the text changes to Blacklist site.

That means the attachment you are previewing is not a valid attachment for being able to open by Google apps (like document, excel sheet, zip file, image, etc.). If any attachment is not considered as secure for security reasons then in that case also, Google won't make it available for preview. The only remaining option that Google can do for you in this situation is to let you download so that you may find some other tools to open that attachment.

I solved it reenabling Flash option in Chrome settings (for mail.google.com site)

Another option is if you have another email provider, like Yahoo for example, you can send the email to your Yahoo account and open the attachment there.

This related to security settings which IT department of companies set in order to make documents handling more secure. Contact your IT department. They should be able to provide a solution to this. It has got nothing to do with Google figuring out what is secure/ not secure documents.
