Affected users may face difficulties accessing their mailboxes through Outlook on the web, Outlook desktop, Exchange ActiveSync and REST-based connections. Email delivery may also be delayed.
Microsoft said the Microsoft 365 admin centre pages might fail to load, while users of Microsoft 365 applications could be unable to access their recently used files.
Microsoft 365 Copilot users may also experience problems loading Copilot Chat or receiving responses. Some Copilot features may be unable to access workplace data, including emails, calendars and files.
Microsoft Teams' core functions, such as joining calls and meetings, group chats and channel messaging, were largely unaffected, the company said. However, calendar-related services, the creation of live or virtual events, Copilot responses and contact synchronisation were among the affected features.
Other services reporting disruptions include Microsoft Defender for Office 365, Defender XDR, Microsoft Fabric, Microsoft Graph, Microsoft Intune, Microsoft Planner, Microsoft Purview, Microsoft To Do, Power BI, SharePoint Online, Universal Print and Windows 365.
Microsoft said its investigation was focused on sustained traffic management imbalances. The company is reviewing traffic flows and affected infrastructure to identify opportunities to optimise routing and determine the reasons behind the service failures.
