Digitally Signed and Encrypted Email

Digital Signing and Digital Encryption Support

Digitally signed emails are supported with Hosted Exchange Email Professional accounts in Outlook or Outlook Web Access.

To sign or encrypt email digitally, you will need a Digital Certificate, such as those provided by Comodo. Go to their site and follow the "Get it Free Now" link.

Please Note: In order to digitally encrypt an email to any recipient, both you and the recipient must have a valid digital certificate. Also, you must save the recipient in your Contacts along with a copy of the recipient's public key. Therefore, before you can exchange encrypted emails with the recipient, you may need to first exchange digitally signed emails.

In order to digitally encrypt an email to any recipient, both you and the recipient must have a valid certificate. Also, you must save the recipient in your Contacts with the recipient's public key. Therefore, before you can exchange encrypted emails with the recipient, you may need to first exchange digitally signed emails. Alternately, if the recipient is a member of the Global Address List for your organization, the user can publish their certificate to the GAL using Outlook 2003/2007 (using the MAPI Protocol) and you'll be able to exchange encrypted emails without exchanging signed emails.

Then when you are composing a message in Outlook 2003/2007, simply select the Digital Encryption button to Digitally Encrypt your email.

In order to Digitally Encrypt an email sent using Outlook Web Access, you will need to match the following requirements:

• You must log into the Premium OWA over HTTPS (at https://ex.myhosting.com/owa) using Internet Explorer 7.0 or higher.
