If you’re a user of the Outlook Web Access (OWA) client, you might have come across this error – ‘The Content Can’t Be Displayed Because The S/MIME Control Isn’t Available’. It’s quite frustrating as this error prevents you from opening any of your emails or download any attachments.
In this guide, I’ll help you understand what this error is and I’ll also give you step-by-step instructions on how you can fix it easily.
What Is The ‘The Content Can’t Be Displayed Because The S/MIME Control Isn’t Available’ Error?
To understand what this error means, you should first know what is S/MIME.
S/MIME stands for Secure/Multipurpose Internet Mail Extensions. It is the technology that encrypts your emails and protects them from unwanted access. You can install S/MIME control for your Outlook Web Access to add further security to any emails that you’re sending or receiving. It will provide a digital signature that assures recipients that the emails are not being tampered with.
However, sometimes your Outlook client might have trouble working with the S/MIME control service, and you will not be able to open any more emails or attachments. That’s when you will get the error message – ‘The Content Can’t Be Displayed Because The S/MIME Control Isn’t Available’.
What Causes ‘The Content Can’t Be Displayed Because The S/MIME Control Isn’t Available’ Error?
Since many users have reported this error, I checked with a couple of them to find out what were the most common reasons for it to happen. Here they are.
- S/MIME Incompatible With Current Version Of Internet Explorer – If your S/MIME control service is not recognizing Internet Explorer as a browser, or if there are compatibility issues between the both, it can stop working and prevent you from accessing any more emails.
- Administrative Privilege Not Granted – Internet Explorer has to run in administrator mode so that necessary permissions can be granted to the S/MIME service.
- Incorrect Installation Of S/MIME – If S/MIME control is not installed, or if it wasn’t installed properly, it will not work as intended. A fresh install is advised in this case.

This is the first troubleshooting methods that you have to attempt.

Here’s how you can set the option to start IE with administrator privileges anytime you open it.
