11:32 AM		Status Service Degradation Impacted services Exchange Online Title: Users may be unable to view or use the scroll bar after composing an Outlook on the web email using the "To" button User impact: Users may be unable to view or use the scroll bar after composing an Outlook on the web email using the "To" button. More info: Specifically, the scroll bar for contact lists may not appear and while we work on remediation, users may be able to search for the intended user or utilize the desktop client as interim workarounds. Current status: Our HAR log analysis has focused our investigation to a potential code issue associated with the scroll bar within Outlook on the web. We're further analyzing a portion of the Outlook on the web code to help us confirm our findings and to isolate our next steps for remediating the impact. Scope of impact: Any user serviced by the affected infrastructure who is attempting to compose an email using the "To" button may be impacted.

Current status: We've developed and are preparing to deploy a service optimization to alleviate impact immediately. In parallel, we're continuing to review potential long-term restoration plans to fully resolve this issue. Scope of impact: Some users whose request are routed through the affected subset of infrastructure may see delays when accessing Exchange Online or leveraging features through Outlook on the web. Start time: Monday, April 1, 2024 at 10:00 AM ADT Root cause: A recent infrastructure update deployed a code change to an authentication component, which is causing the component to consume more resources than the infrastructure can handle, resulting in impact.
