Title: Users may be unable to connect to multiple Microsoft 365 services 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: Failures may occur for scenarios including access to Safe Links, Safe Attachments, protection and submission policies, and attempts to view Quarantine, Threat Explorer, and Email remediation events. Additionally, delays may occur for Tenant Allow / Block list changes, unified Role-Based Access Control, reporting, message traces, content extraction, and outbound protection. Users clicking on wrapped/rewritten URLs typically processed by Safe Links will result in a failure to navigate, as Safe Links fails to process it. Users who are able to successfully access the Quarantine portal may encounter failures when attempting to release items from quarantine. - 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, when updating artifacts with sensitivity labels, or opening pbix with sensitivity label in Power BI Desktop. As a workaround, users can remove the sensitivity label from the affected item to complete the operation, if their organization's data protection policies allow it. - Microsoft Graph: API requests that access Exchange Online data, such as mail, calendar, and contacts, may time out and prevent users from managing Teams, Channels, Membership, Apps management and send activity notifications using Graph API. - Microsoft Intune: Scenarios including device enrollment, device check-in, and device compliance policies may have been intermittently impacted. - Microsoft Planner: Users are experiencing Plan and Task operation reliability issues. - Microsoft Power Apps: Users may be intermittently unable to sign-in to the Power Apps or Field Service mobile apps. Affected users may be able to utilize Power Apps or Field Service on the web as a way to circumvent impact, and users who are already signed in can potentially avoid impact by not signing out, clearing app data, or reinstalling while the issue is ongoing. - Microsoft Purview: Multiple Purview services including Authorization, auto-labeling, Data Loss Prevention (DLP) across Microsoft 365 services, Communication Compliance, Information Protection label and auto-labeling policies, Role-Based Access Control (RBAC) and Data Classification are impacted, and users may be unable to open or load Microsoft Purview portal pages or protected content. Audit searches, protected content creation, eDiscovery tasks such as search and export, Data Classification and On Demand Scan features may also be impacted. - Microsoft Teams: Most of the core functionality including joining calls, meetings, group chats, and channel messages are not impacted. Scenarios that depend on Exchange Online, including Calendar related failures with scheduling, invites, viewing, and meeting edits. Creation of Live or Virtual events fail. Failures with Copilot responses for outlook, calendar, or M365 files, read history, or adding to new chats. Navigating to App chats, adding new contacts or syncing contacts in settings fail. Standard channels are working fine but users may experience the inability to create or delete private or shared channels. - 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: Some users may experience issues when sharing SharePoint Online files with people outside their organization, where external sharing is permitted by both organization-level and site-level settings. Additionally, 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’re continuing to see increased server capacity stability after applying the upstream authentication/routing configuration component patch. With confirmation of server stability across the portions of infrastructure to which we've applied the patch, we’ve initiated its expansion systematically to focus on infrastructure supporting regions currently within or entering peak business hours. We’ll continue to monitor the status of changes applied and develop additional modifications intended to improve server stability and capacity. As of now, we are not aware of any malicious activity that is causing this incident. We will continue to treat this incident with urgency and priority until full resolution. Once mitigated, we will provide full details of the root cause, defense-in-depth repair items, and more within a Post-Incident Report. Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services. Next update by: Friday, November 13, 2026, at 9:00 AM UTC
Title: Some users may see delays receiving policies, apps, and other changes on Windows devices enrolled in Microsoft Intune User impact: Users may see delays receiving policies, apps, and other changes on Windows devices enrolled in Microsoft Intune. More info: A recent Windows security update, MSRC144654, can cause a single device check in to fail during installation. Affected devices receive pending changes at their next successful check in. Users can check in manually after the update finishes instead of waiting for the next scheduled check in. Current status: We’ve confirmed that a recent Windows security update, MSRC144654, can cause a single check in to fail during installation. We’re developing a fix to address this issue and anticipate its release for early December 2026. We’ll provide a better estimate for the delivery of our fix when available. Scope of impact: Some users with Windows devices enrolled in Microsoft Intune may experience delays receiving policies, apps, and other changes while their devices install Windows security update MSRC144654. This information may be updated as our investigation continues. Root cause: A recent Windows security update, MSRC144654, can cause a single check in to fail during installation.

Our team has identified the root cause of the issue affecting automations and is working to resume regular service usage. We are waiting on issues to be resolved on Microsoft's side, but we will continue to provide updates on any progress.
We have identified the issue of delayed email delivery to Microsoft inboxes. Due to a third-party provider dependency, messages may continue to be deferred before reaching recipient inboxes, though mail send is not impacted and queued messages will continue to retry. We will provide another update by 7:00AM PST or as soon as more information becomes available.
We continue to work with our underlying vendor affecting Microsoft Integrations. Our team is actively working on a resolution, and we will keep you informed with timely updates as progress is made. Thank you for your patience.

Fabric customers may encounter failures when exporting reports with sensitivity labels to PDF or PowerPoint, when publishing reports with sensitivity labels, when updating artifacts with sensitivity labels, or opening pbix with sensitivity label in Power BI Desktop. The cause is an ongoing Microsoft Exchange service outage. As a workaround, users can remove the sensitivity label from the affected item to complete the operation, if their organization's data protection policies allow it. We're monitoring Exchange recovery and will share an update by 1:00 AM PST.
