Before you install an email certificate

Make sure you request and download your S/MIME certificate first. Learn more about how to request and download a GlobalSign S/MIME certificate.

Note
The certificate must be issued to the same email you are sending from. If the certificate was issued to your friendly email (e.g. firstname.lastname@uwaterloo.ca), please enter it into the Full Email Address field, otherwise you can enter your 8-character username @uwaterloo.ca (e.g. j25rober@uwaterloo.ca)
