The work is underway. We'll keep you updated on our progress.

Scheduled

We're making a change to Office 365, during which time the service will be available but at risk.

IMAP and POP3 are older methods used by computers to access email messages from a remote server. The connections do not support multi-factor authentication (MFA) and can be used by many hackers to access university information and send malicious emails.

While we don't expect any issues, sometimes unexpected things happen. We'll update this post with progress.
