Subject: Important: on-campus email service breach

We are aware of a breach involving our on-campus email service (Microsoft Exchange). This service has now been isolated. Most Microsoft Exchange accounts are currently housed in the cloud and are not affected. This means that for most people on campus, your email access is unaffected.

As we continue to investigate the impact of this breach, we may need to isolate more services which means you may not be able to access some systems throughout the day today. 

We will continue to share information as it becomes available on the IST News pages. If you have questions about access to systems today, please email with any questions you may have.
