Summary

When you try to open a Zero download message through OWA, the following error message shows:

The message could not be opened

Details

This issue happens because the critical software updates that provide support for safe HTTP are required to read Zero Download messages in OWA. Some mail scanners and content filters may also cause this error message by modifying the HTM file.

To resolve the issue, do one of the following:

For Exchange 2007, apply Service Pack 1 and the latest updates. Execute the command below on the Exchange administration console:
Set-OwaVirtualDirectory -identity "Owa (Default Web Site)" -FilterWebBeaconsAndHtmlForms DisableFilter

For more details, refer to the Microsoft article Configure Web Beacon and HTML Form Filtering for Outlook Web App.
For Exchange 2003, apply the patch from the Microsoft article A software update for the Safe HTML filtering feature is available to enable you to use the POST method in HTML forms in Outlook Web Access for Exchange Server 2003.
