Purpose: Secure Email (S/MIME) certificate installation guide
For Secure Email (S/MIME) certificate on Microsoft Outlook 2010 on Windows OS
The installation is in four parts:
1) Installing the S/MIME certificate in the personal certificate store
2) Updating Security Settings to link the S/MIME certificate to Outlook profile
3) Signing and encrypting messages
4) Storing a contact's secure email certificate (S/MIME exchange)
1. After your ECS Enterprise account administrator has approved the enterprise S/MIME request, or after you have placed your personal S/MIME order, you will be sent an email at the address listed on your request. Select that link.
2. Accept the Client Certificate Agreement that is presented in the browser that opens when you select the certificate pick-up link.
3. Once you have confirmed you can download the certificate, you are prompted with the below "Web Access Confirmation" pop-up. Select "Yes". The prompt is asking you to allow Entrus to perform digital certificate operations on your behalf, which is required to allow in order to complete the next steps.
4. Your browser will prompt you to download (open or save) a .p12 file. Open the file.
5. A Certificate Import Wizard will open. On the first prompt, select "Current User" and then Next.
6. Confirm you wish to import the .p12 file from the location shown by selecting Next.
7. When you requested the certificate, you were prompted to set up a password to protect the private key. Provide that password here. Select "Mark key as exportable..." in case you need to export your certificate in the future.
8. Select the option "Automatically select the certificate store based on the type of certificate".
9. Complete the Wizard by selecting Finish.

Part 3 of 4: Signing and Encrypting Messages
To Sign an Email Message, simply click the Sign button that now appears on a Compose Message email dialogue. There is no other setup required.
When users receive your email, they will see a message that the email has been digitally signed.
However, note to exchange secure emails with someone, there are some additional steps required.
To Encrypt an Email Message, you will need to provide your public key to the party you wish to encrypt for, and vice versa.
The recommended way to do this exchange is to send the other party a Signed email. This email will contain a copy of your public key. The other party should send you a signed message as well, so that you can obtain a copy of their public key.
After receiving the Signed email containing a copy of the other person's secure email certificate, you need to store that contact and certificate.
1. Rick click on the sender name.
2. Select Add to Outlook Contacts.
3. You can make sure the user's certificate has been stored by clicking on Certificates.
4. Click Save and Close.
| You can now exchange encrypted emails with that user. |
