OIT will be migrating all active ES Mail (aka Webmail) accounts to either Google Workspace or Microsoft 365 in an effort to increase email security. Migration will happen on a rolling schedule, and each user group will be notified with ample time prior to their ES Mail accounts being migrated and subsequently deactivated.
Why is OIT Decommissioning ES Mail (aka Webmail)?
As part of the larger security initiative championed by UC Regents, the Email Security Initiative was created to proactively address an increasing frequency of malicious online attacks worldwide.
Attacks on email systems, such as phishing, account compromises, malware injections, and data breaches cost the higher education sector almost $3M on average per incident. Data belongs to the institution, and our objective is to minimize UCI’s vulnerabilities to potential attacks by moving to modern, secure services.
Decommissioning ES Mail and migrating existing users and their data to enterprise-grade, secure email systems is a key step in our plan to raise the bar on the security and integrity of UCI’s data.
