To work around this issue, close Internet Explorer 11, reopen the page in compatibility mode, and then the S/MIME option will work as expected.
- When you use this workaround, Internet Explorer 11 saves your Compatibility View settings for the website. Every time that you access the Outlook Web App site, Compatibility View will be used.
