Digital signatures identify/authenticate you as the document signer and allow document recipients to verify that no one has modified the contents of the document since you signed it. Signing, Encrypting and reading will vary depending on the applications that are involved.

Things to Note..

Depending on the following scenarios you may have to import your Digital ID into your Windows personal Certificate Trust Store.

  • If one of these two scenarios effects you then reference our guide. How To Import A Digital, Email or Code Signing Certificate Into A Windows System.
    • Your Digital ID was picked up using Firefox. Firefox has its own trust stores separate from Outlook/Windows and therefore Outlook will never see the certificate on your system.
    • You are moving your Digital ID from one System to another.
  • Sending and viewing encrypted email messages requires both sender and recipient to share their digital ID, or public key certificate. This means that you and the recipient each must send the other a  digitally signed message, which enables you to add the other person’s certificate to your Contacts. You can’t encrypt email messages without a digital ID. So if this is a first time deal then send a digitally signed document at first, once they respond with their own digitally signed email, then you can start encrypting. 

Otherwise or after your Digital ID has been imported into the trust stores of your windows system continue with the below configuration instructions. If you already configured your Outlook with your email certificate skip to the below Step 2: How to digitally sign and encrypt an email in Outlook:
