Install S/MIME

As a first step, please ensure that S/MIME is installed and you receive an error message if it does not work. Also, if you update your operating system, its installation may be interrupted or settings may be reset.

  3. To download the S/MIME control, click Settings, then S/MIME, then Download.

  5. Right-click on the message and select “Run on all websites” when your browser reloads.
  6. You will be prompted to run the security alert.

Add OWA to Trusted Sites and use the compatibility view

Add OWA to Trusted Sites in Internet Explorer to avoid many problems and use compatibility view to make it compatible with different versions of the web browser and OWA. This is the most effective way to fix the error – S/MIME control is not available.

  1. To open Internet Explorer’s Internet options, click on the gear icon at the top of the page.
  2. Click Trusted Sites – Sites on the Security tab.
  3. Select all sites within the area, and remove the server validation required (https:) by pasting the OWA site into the new window.
  4. You can find display settings for compatibility by clicking on the gear icon on the home page.
  5. Click on the “Add” button and paste the same link.

Uncheck the “Internet Options” section.

If the S/MIME control is not working in Internet Explorer, you can disable the option.

  1. You can find advanced options under Internet Options.
  2. Delete the checkmark in the Security section that prevents the disk from storing encrypted pages.

Use Internet Explorer as an administrator

In Internet Explorer, S/MIME requires administrator rights sometimes to work.

  1. Select the exe file’s properties by right-clicking it in C: Program Files: Internet Explorer.
  2. Make your changes by clicking “Shortcut” – > “Run as administrator”.
