There’s still an alternative. A few smart users have found their own solutions and we’ve collected them all into one place for you to look through.

What is the Reason the Content Can’t be Displayed Because The s/Mime Control Isn’t Available.

The message can’t be displayed due to the fact that the S/MIME control cannot be found” This error is typically encountered in software or email clients whenever they face issues related to the S/MIME (Secure/Multipurpose Internet Mail Extensions) control.

S/MIME is an extension protocol that’s utilized to secure messages in emails through encryption and signing digitally.

If the error message shows up it indicates there’s an issue with the control, which means it is not able to fulfill its functions as intended. There are a few common causes to be concerned about:

  • S/MIME is not enabled One of the most frequently cited reasons is that S/MIME’s functionality is not activated or correctly configured within the email client you use. It is possible to examine the settings of your email client to make sure that S/MIME is turned on and configured correctly.
  • Incorrect or outdated S/MIME plugin Your email client might require a particular S/MIME plugin or an extension in order to handle digitally signed and encrypted emails. If the plugin you are using is not installed or out of date, it may cause an error message. Check that you’ve got the required S/MIME software running and current.
  • Certificate Problems S/MIME uses digital certificates to confirm the legitimacy of the person sending the message and to decrypt and encrypt messages. When there is an issue in the certificate that is not valid, like an expired or invalid certificate, it could cause an issue. Make sure that the certificates you have are in good condition and properly configured within your email client.
  • Corrupted S/MIME Control The S/MIME control inside your email client could become damaged or fail. In these instances, you might need to update or reinstall the S/MIME control in order to correct the problem.
  • An Email Program that is Not Supported Some email clients work with S/MIME. If you’re using an email program that doesn’t have S/MIME support, you’ll experience this error while trying to open protected emails with S/MIME. You should consider using an email client with S/MIME support for secure email communications if it is important to you.
  • Firewalls or Security Software The use of overly restrictive firewalls or security settings installed on your system could hinder or block S/MIME’s functionality. It is possible to modify the settings of your firewall in order to let S/MIME be used.
  • Server configuration In certain cases the problem could lie at the server’s end. Incorrect configurations or restrictions in the server may hinder S/MIME from functioning properly. You should contact your email company or the IT department for assistance in identifying issues with servers.
