For quite a long time I have been trying to figure out a way to do this without modifying the 'EmailDisplay' Processor, and it looks like I finally managed to, partially thanks to ServiceNow introducing a new property to store the email body style settings in one of the last few releases.

What am I talking about? How about an easy, 1-click way to open a sys_email record straight from the Activity log?

Here's how to achieve this.

1. Create a new String property glide.ui.activity.style.email
2. Set its value to this script:
   } </style> <script> function goToEmail() { const queryString = window.location.search; const urlParams = new URLSearchParams(queryString); const email_id = urlParams.get('email_id'); window.open('/sys_email.do?sys_id=' + email_id, '_blank'); } </script><p><button onclick="javscript: goToEmail()">Open Email record</button></p> <style> <!-- PUT YOUR CUSTOM EMAIL BODY STYLE HERE --> body {​

And voilà! Now when you click the 'Show email details' link, you will see a button on top of the email body that, when clicked, will take you directly to the email record!

UPD: Now available on Share!
