We are aware of some customer seeing an SSL or "Not Secure" connection warning when visiting their webmail. Our team is working on getting this back to secure, however in the meantime, please click through the message and it should load as normal the next time you visit the site. This does not impact your current ability to send and receive emails.
Given the advanced age of the platform, we continue to encourage our valued clients to work with our team on migrating your services to a newer and more robust service to ensure long-term reliability and to avoid repeat issues.
