We’re getting reports that some Outlook and Office 365 users may be experiencing issues with logging into OWA and Microsoft 365 services. Affected users are unable to authenticate to and access Microsoft 365 services. Microsoft has identified a degraded portion of infrastructure that manages authentication requests and have restarted that infrastructure to mitigate impact. We're investigating the issue, and working with Microsoft to fix the problem. We will update when we know more.
If you’re one of the affected users, or would like more details, please contact us at (310) 825-8000 or help@it.ucla.edu.
