Developing an add-in for Outlook on the Web for Sending Secure Email

I'm working on a project that involves the development of an add-in for outlook the web for the purpose of sending secure email.

I have a few requirements for this add-in:

  1. It must be able to have access to smart card reader and read certificates from it.
  2. It must be able to sign and encrypt mail using S/MIME
  3. Ideally, should also work on mobile (e.g. iPhone, Andriod).

From my current research, I understand that there are some restrictions regarding add-ins for Outlook. The main one being it won't be activated for encrypted mail... But I have noticed that some people are able to work around this limitation.

Hoping to get some promising leads from the experts here.

Thanks!

  • Currently add-ins are not supported on S/MIME encrypted messages and are not available for mobile compose scenarios. We track Outlook add-in feature requests on our user-voice page. Please add your request there. Feature requests on user-voice are considered when we go through our planning process.
