Status bar message "An error occurred while formatting. Press ESC to close window." and extremely limited and/or corrupt display of email.

IBM Notes 9.0 Client
Resolving the problem
Enable the use of the system's embedded browser (this is the default). This will use the system's web browser to display the HTML content of MIME-formatted emails, bypassing the limitations of Notes' parsing and rendering.
