How do I send encrypted emails?

You will need to have purchased and installed a digital id on your computer (How do I do that? )

  • To send someone a encrypted message you will need a copy of their recipient's digital ID. Ask them to send you a digitally signed message
  • Open the message
  • Right-click the name in the From field
  • Select Add to Outlook Contacts
  • Click Save and Close
  • Note: If an entry for them already exists, select Update new information from this contact to the existing one
  • Click OK
  • Click on New Email to open a new message
  • Click on the Options tab
  • On the More Options section click the arrow in the bottom right hand corner
  • Click Security Settings...

  • Check the Encrypt message and contents and attachments box
  • Then click the Change Settings...
  • Then click the Choose... and select the Encryption Certificate
  • Then Click OK then OK then Close

To configure Outlook to digitally sign all outgoing emails in Outlook:

  • Open Outlook and click on New Email to open a new message
  • Click on the Options tab
  • On the More Options section click the arrow in the bottom right hand corner
  • Click Security Settings...

  • Check the Add digital signature to this message box
  • Click OK

Note: We recommend that you DO NOT choose to Encrypt contents and attachments for outgoing messages as this means every person you email must have a digital certificate to read your messages.
