To view the settings, you have two options:
Option 1: From the inbox, press ‘File’, then ‘RMail Settings’.
Option 2: From the feature pop-up, press the ‘Settings’ button.
The attachment options control the ‘Convert to PDF’, ‘Metadata Cleaning’, and ‘File Compression’ settings on the feature pop-up.
The ‘Convert to PDF’, ‘Metadata Cleaning’, and ‘File Compression’ settings each have two options. The first is to enable the feature on the feature pop-up. The second is to have the feature pre-selected for all messages that include attachments. All three options have the first option checked and are enabled on the feature pop-up.
