If you want all your outgoing emails to be encrypted, click on the ‘File’ tab then choose ‘Options’ in that select ‘Trust Center’ and then ‘Trust Center Settings’. Now to make every email message encrypted, click on ‘Email Security’ once the window opens. Now, check the box which reads as ‘Encrypt contents and attachments for outgoing messages’. You can even choose a specific Digital ID by heading over to Settings in the same window.
The recipient of the email should have matching Digital ID to access the emails. Else, they’ll see this notice:
“This item cannot be displayed in the Reading Pane. Open the item to read its contents”.
In spite of it, if they try to open they’ll see the below message:
"Sorry, we’re having trouble opening this item. This could be temporary, but if you see it again you might want to restart Outlook. Your Digital ID name cannot be found by the underlying security system".
