In a previous article, we provided a step-by-step guide on email encryption for webmail accounts. This article shows how to enable email encryption on Microsoft Outlook 2010.
To start encrypting your Outlook email, you'll need to get a Digital ID first. A Digital ID is an electronic signature that you can use to ‘sign’ your messages, to prove that the sender is in fact you and you alone. Don’t confuse it with the message signature, i.e. the ‘signature’ text at the bottom of emails – those can easily be copy-pasted no matter how flashy or formal they look.
How to generate a Digital ID:
From there, follow the steps to get a Digital ID. Note: some services will charge you for a Digital ID.
Now, if you already have your own Digital ID, the next step is to share digital IDs with the person you plan on sharing encrypted messages with. To do that, you need to send them a digitally-signed message that uses the Digital ID you just got.
How to send a digitally-signed message:
From there, you should see a new option in the Permission Group, namely the Sign Message button. Click that, compose your message, and then send it. From there, have the other party reply to it with a digitally-signed message of their own, so you can add their Digital ID.
To add their Digital ID, right-click on their name in the From box, then click Add to Outlook contacts. If you already have them added to your contact list, then simply select Update information of selected contact.
Set Outlook to encrypt your messages:
That last step enables email encryption on MS Outlook. Again, remember that you need to be using the same encryption method with the person you’re sending the encrypted messages to.
