Windows File Explorer does not preview .msg file in Preview Pane when Outlook is not installed or when you have the 64-bit version of Microsoft Outlook installed. In this situation, you receive the following error message:

After you select OK, the following error message is displayed in the Preview Pane:

Cause

The Windows preview host requires a 32-bit application previewer. When 32-bit Outlook is installed, it acts as the previewer. Without 32-bit Outlook installed, there is no previewer available for .msg files.

Workaround Method 1 - Use 32-bit Outlook

If you prefer to preview .msg files in Windows File Explorer, install the 32-bit version of Outlook instead of the 64-bit version.

Workaround Method 2 - Use MSG Viewer

1. In Windows File Explorer, on the View tab, select the Preview pane to disable it.
2. Install MSG Viewer and preview the .msg files.

Standalone & Installer versions

MSG Viewer can be used as a portable application or installed as a Windows application. The software doesn't require Microsoft Outlook to be installed on the PC.

Advanced Search Option

Based on your preference, use Instant Search or Advanced Search with various search keywords to narrow your search criteria for better searches in .msg files.

Open Email Files with One Click

The MSG Viewer can be set as the default application for .msg and .eml files to open, read and search for e-mail files on your hard drive, network share or USB drive.
