Global Microsoft 365 Outage

User impact: Users may be unable to connect to multiple Microsoft 365 services.

More info: Features of the Microsoft 365 services below that interact with Exchange Online and email services are impacted. Elements of those services that do not depend on interaction with Exchange Online remain functional.

• Exchange Online: Users may be unable to access their mailbox using Outlook on the web, Outlook desktop (MAPI), Exchange ActiveSync (EAS), or REST-based connections, and email delivery may be delayed.
• Microsoft 365 admin center: Admins may be unable to load some admin center pages.
• Microsoft 365 apps: Users may be unable to view their recently used files. -Microsoft 365 Apps Admin Center: Multiple services including Cloud Update, Cloud Policy, and Inventory are affected.
• Microsoft 365 Education: Features including Assignments, Reading Progress, and Speaker Progress may be impacted.
• Microsoft Copilot 365: Users may be unable to load Copilot Chat or receive responses in the web and desktop apps, and Copilot experiences may be unable to access work data such as email, calendar, and files.
• Microsoft Defender for Office 365: Safe Links may be unable to verify URLs, which may impact users clicking links in Outlook and Teams.
• Microsoft Defender XDR: Users may be unable to load Microsoft Defender portal pages or solution tabs.
• Microsoft Fabric: Users may encounter failures when exporting reports with sensitivity labels to PDF or PowerPoint, or when updating artifacts with sensitivity labels.
• Microsoft Graph: API requests that access Exchange Online data, such as mail, calendar, and contacts, may time out.
• Microsoft Intune
• Microsoft Planner: Users are experiencing Plan and Task operation reliability issues.
• Microsoft Purview: Multiple Purview services including Authorization, auto-labeling, Data Loss Prevention (DLP), Communication Compliance, and Data Classification are impacted, and users may be unable to load Microsoft Purview portal pages.
• Microsoft Teams: Scenarios that depend on Exchange Online, including calendar, meeting scheduling, and creating chats for organizations using Information Barriers, may fail. Core messaging and online meetings remain largely functional.
• Microsoft To Do: The app may not load, and users may see operation failures.
• Power BI: All users may intermittently be unable to export reports with MIP sensitivity labels to PDF in Power BI.
• SharePoint Online: Features that depend on Exchange Online may be impacted. Accessing files stored directly in SharePoint Online remains functional.
• Universal Print: Users may encounter errors submitting print jobs or using admin features.
• Windows 365: Customers who have configured their tenant and Cloud PCs to use Microsoft Purview Customer Key for Windows 365 Cloud PCs may have users who are unable to connect to their Cloud PCs.

Current status: We've reviewed known impact scenarios and have revised the list of impact services and features, which can be viewed in the "more info" section of this communication. We're continuing our work to isolate the issue affecting server availability, as well as other workstreams.

Previous status: While the servers we've returned to service initially remain healthy, we've observed that they can become unresponsive again once they begin receiving traffic. We're analyzing diagnostic data from these servers with our networking and platform experts to determine what's triggering this behavior. Building on the protective traffic management measures we've implemented, we're also temporarily limiting which types of traffic can reach the affected infrastructure in specific locations. This will help us determine whether a particular type of request is contributing to the impact and allow us to restore service incrementally. Additionally, we're rebuilding a subset of affected servers using a previous software configuration to validate whether this prevents them from becoming unresponsive, and we'll expand this approach to additional servers if we observe positive results.

Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.

There is currently a Global Microsoft 365 Outage impacting Outlook, Teams and Sharepoint.

For updates, please refer to Microsoft Status Page https://status.cloud.microsoft/

User impact: Users may be unable to connect to multiple Microsoft 365 services.

More info: Potentially impacted services include:

• Exchange Online
• Microsoft Teams
• SharePoint Online
• Microsoft Copilot 365
• Microsoft Defender XDR
• Microsoft Planner
• Microsoft To Do
• Microsoft Intune
• Microsoft Defender for Office 365
• Microsoft Purview: Multiple Purview services including Authorization, Auto Labelling, Data Loss Prevention (DLP), Communication Compliance, and Data Classification are impacted.
• Power BI: All users may intermittently be unable to export reports with MIP sensitivity labels to PDF in Power BI.
• Microsoft 365 Apps Admin Center: Multiple services including Cloud Update, Cloud Policy, and Inventory.
• Universal Print: Users may encounter errors submitting print jobs or using admin features.

Current status: We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We’ve also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.

We've streamlined our recovery process to expedite returning the remaining affected servers to service. To further support recovery, we're implementing protective traffic management measures in a specific location to reduce load on the affected infrastructure, and we'll expand these measures to additional locations if we observe positive results. As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service.

Previous status: We’re continuing to pursue all available pathways to restore service, as our actions taken thus far have not provided the anticipated relief. Our investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss.

To validate a potential recovery approach, we're fully isolating a portion of our service infrastructure, restarting the affected components, and gradually reintroducing traffic to confirm our services remain stable before applying this approach more broadly. We're also analyzing traffic patterns across our entire service infrastructure and evaluating whether isolating traffic within each region may allow affected regions to recover independently.

Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.
