Exchange Online
- Users may have been unable to access their Exchange Online mailboxes
- Admins may have been unable to provision Exchange Online mailboxes
Microsoft Teams
- Users may have been unable to create group scenarios, including chats, channels, and Teams

Final status: After an extended monitoring period, we confirmed that all services and scenarios impacted by this event have recovered.
Scope of impact: Users in any region leveraging Microsoft 365 services, whose requests were routed through the affected infrastructure were impacted by this event.
Start time: Monday, June 16, 2025, at 9:45 PM UTC
End time: Monday, June 16, 2025, at 11:30 PM UTC
Preliminary cause: Authentication Traffic Control (ATC) is a system in which we define a set of parameters by which we want to block traffic. We refer to this set of parameters as a traffic control policy. We perform policy changes via ECS so that they take effect more quickly.
We identified an opportunity to refactor ECS flights to improve internal manageability of the service and to ensure smooth rollout cadence as a step to better improve service resiliency.
In this particular scenario, we were working on blocking external and Hosted on behalf of (HOBO) traffic to harden our traffic pipeline. We deployed this change in our internal testing environment and did not observe any impact. Once validated, we continued our rollout and then we started to receive internal monitoring alerts.
We determined that the change was missing a key parameter, resulting in the service falling back to default values in the service configuration which resulted in inadvertent blockage of all traffic.
This issue was not detected within our internal environment as the change itself contained the correctly defined parameters; however, once it started to reach our Production environment, the parameters were defaulted.
Next steps:
For a more comprehensive list of next steps and actions, please refer to the Post Incident Review document.
We'll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.

| Root Cause: | The incident occurred because two changes were made in two separate deployment pipelines, and they required manual verification and sequencing of the deployments.
- Change 1 (A): Allowed a Copilot service to call Microsoft Graph with permissions to interact with Data Loss Prevention (DLP) policies.
- Change 2 (B): Included the DLP policy permissions in the token for when the clients acquire the token for Copilot services. |

| Description: | Title: Users may be unable to utilize Microsoft Copilot (Microsoft 365) services and features
User impact: Users may have been unable to utilize Microsoft Copilot services and features.
More info: Users may have received an error message stating that “Service Communication is currently unavailable” when submitting a prompt to Copilot.
Users may have experienced impact in all enterprise Copilot apps when submitting queries, including those for Microsoft Teams, OneDrive, SharePoint, and Microsoft 365 apps like Excel and Word. In most scenarios, users received a “something went wrong” error, or the error messages described below.
A small subset of affected users may also have seen a banner communication describing the impact in some Copilot apps.
Additionally, users may have received an error message stating “There was a problem reaching the app” when attempting to open the Microsoft Teams Copilot app.
Final status: We’ve completed the remediation process and verified through telemetry analysis and working with previously impacted customers that the issue is resolved.
Scope of impact: Any user attempting to leverage Copilot services and features may have been impacted.
Start time: Wednesday, June 4, 2025, at 5:15 PM UTC
End time: Wednesday, June 4, 2025, at 9:00 PM UTC
Root cause: The incident occurred because two changes were made in two separate deployment pipelines, and they required manual verification and sequencing of the deployments.
- Change 1 (A): Allowed a Copilot service to call Microsoft Graph with permissions to interact with Data Loss Prevention (DLP) policies.
- Change 2 (B): Included the DLP policy permissions in the token for when the clients acquire the token for Copilot services.
The second change (B) was dependent on the first change (A) being fully saturated across the environment.
Due to a process miss in the manual verifications and sequencing processes, an oversight occurred, and it was believed that the first deployment (A) had fully completed when it hadn’t, and the second deployment (B) was started. Clients started failing to acquire the tokens in sections of the environment that received the second change (B) but not the first change (A).
The issue was detected by client-side monitors, and a roll forward was required to revert the second change and fix the problem.
Next steps:
For a more comprehensive list of next steps and actions, please refer to the Post Incident Review document
We'll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.

| Description: | Title: Users may have been unable to submit web search requests under the Web tab in Microsoft Copilot (Microsoft 365)
User impact: Users may have been unable to submit web search requests under the Web tab in Copilot.
More info: Affected Copilot desktop users received the following error when submitting a search request: "Your organization has turned off web search. Copilot responses won't include the latest data from the web."
Users could have used Copilot web as a workaround while the Copilot desktop deployment was completed.
Final status: We’ve successfully deployed the desktop fix to the remaining environment that was affected and after an extended period of monitoring we’ve confirmed that impact has been remediated.
Scope of impact: Any user that submitted web search requests under the Web tab in Copilot may have been impacted by this issue.
Start time: Tuesday, May 27, 2025, at 4:35 AM UTC
End time: Saturday, May 31, 2025, at 6:28 AM UTC
Root cause: A recent update to organizational policies inadvertently disabled the Web and Work content grounding setting, which resulted in impact.
The update was designed to fix an issue where the toggle displaying the affected organization policy was always set to enabled. The update changed the policy to allow it to be disabled, but this value was accidently set as a two-value setting (enabled and disabled), instead of a three-value setting (enabled, disabled, and disabled for work/enabled for web) which misaligned the policy and disabled the setting in the Work and Web tabs.
Next steps:
- For a more comprehensive list of next steps and actions, please refer to the Post Incident Report document.
We'll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.

User impact: Users received an error when running flows and apps that utilize the RSS connector.
More Info: Users received the following error when attempting to load the Microsoft-managed blog websites for Power Apps, Power Automate, and Power Pages through the RSS connector:
'502: Bad Gateway'
Final Status: We investigated an issue where users received errors when executing flows and applications that utilize the Microsoft-managed blog websites for Power Apps, Power Automate, and Power Pages through the RSS connector. Our investigation identified that, following a recent service update deployment, the impacted RSS feeds were migrated to new URLs. However, the old URLs were not configured to redirect to the new URLs. Consequently, the outdated URLs remained cached within a portion of the infrastructure accessed by the RSS connector, which led to user impact. We have since cleared the cache on the affected infrastructure and updated the configuration to ensure the old URLs now redirect to the new ones. Following these actions, we reviewed connector diagnostics and confirmed the issue has been mitigated.
This is the final update on the incident.
Preliminary Root Cause: A recent service deployment updated a subset of Microsoft blog RSS feed URLs.
Next Steps: We're reviewing our standard service update procedures to avoid similar impact in the future.

User impact: Users may be unable to utilize automatic forwarding with their Exchange Online mailbox.
Final Status: We’ve concluded our testing effort and have determined that our fix is a viable solution for this issue. Representatives of organizations that would like us to re-forward any messages affected by this event are encouraged to contact Microsoft support and refer to this Service Health Dashboard post ID.
More info: New messages will be automatically forwarded, as per user settings with the deployment of the code fix. However, messages users attempted to forward between 2:04 PM UTC on May 11, 2025, and 5:00 AM UTC May 16, 2025, will not be replayed automatically.
Scope of impact: This issue may impact a subset of users attempting to utilize automatic forwarding with their Exchange Online mailbox.
Start time: Sunday, May 11, 2025, at 2:04 PM UTC
End time: Friday, May 16, 2025, at 4:32 AM UTC
Root cause: During mail flow for auto-forwarding, the transport infrastructure invokes a throttling service via a system call to determine if the target mailbox has exceeded daily auto-forwarding sending limits. If the throttling service determines the sending limit has been exceeded, it denies the requested action, and the auto-forwarding is skipped.
A recent update to the service responsible for enforcing daily sending limits on auto-forwarded messages introduced a code regression, which resulted in the failure to apply the correct limits. Consequently, all auto-forwarding messages were denied on machines where the recent update was deployed.

| Description: | Title: Some of users' Android devices may have become non-compliant, preventing access to any Microsoft mobile service
User impact: Users' Android devices may have become non-compliant, preventing access to any Microsoft mobile service.
More info: This impacts any Microsoft mobile service protected by App Protection Policies.
Admins can disable strong integrity and remove the strong integrity conditional launch check on app protection policies to prevent their devices from being marked as non-compliant
Current status: We've determined that the fix that was deployed by our third-party partner corrected a code issue in a recently deployed Android platform update. While this fix corrected the issue for some, the Android platform update also introduced a change to the compliance calculations that isn’t compatible with Microsoft Intune, leaving some users impacted. We've created and are deploying a code change to correct the compliance calculation compatibility issue to completely remediate impact.
Scope of impact: Some users attempting to access Microsoft services from Android devices with strong integrity enabled may be impacted.
Root cause: A recent update to the Android platform contains a change to the device compliance calculation, which is causing Android devices with strong integrity enabled to become non-compliant, resulting in impact.

| Description: | Title: Users may not receive search results for REST API "/postquery" calls in SharePoint Online
User impact: Users may have not received search results for REST API "/postquery" calls in SharePoint Online.
More info: Some users may have received partial or incomplete results.
Final status: We isolated the cause of impact following our systemic examination into our SharePoint infrastructure. A recent change to a portion of search code path that processes authentication tokens became degraded and resulted in incomplete or unsuccessful search result queries. We’ve disabled the offending change and after a period of monitoring and user confirmations, we’ve determined the functionality has been restored successfully.
Scope of impact: This issue may have affected any user performing searches that rely on REST API "/postquery" calls on SharePoint Online classic sites, SharePoint Framework (SPFx) and PnP PowerShell module search result web parts, and other custom search UIs if served through the affected infrastructure.
Start time: Tuesday, May 13, 2025, at 3:00 PM UTC
End time: Wednesday, May 14, 2025, at 12:30 AM UTC
Root cause: A recent change, intended to create and use a new data code path for authentication tokens for SharePoint Online search requests, was deployed. The new code path did not work as expected in certain scenarios, resulting in incomplete or unsuccessful search result queries.
SharePoint Online search gathers search results from background Store databases by opening a session with an internal service. When retrieving organization level search results, the type of session that needs to be opened with the internal service should be “System”. The recent change inadvertently changed the session type from “System” to “Best Access”, resulting in no search results being returned from the internal service, because the session type of “Best Access” is not configured to support the retrieval of organizational level data.
Next steps:
- For a more comprehensive list of next steps and actions, please refer to the Post Incident Report document.
A Post Incident Report (PIR) has been published for this event.

| Root Cause: | A small section underlying networking hardware in one of the Dallas regional data centers, used by Microsoft 365 services for Azure Front Door (AFD) routing infrastructure, entered a degraded state. A technical issue in the underlying hardware SKUs resulted in some background power throttling. When the throttling kicked in, the processing workloads on the impacted components were slowed down as the Central Processing Unit (CPU) frequency was reduced. This resulted in high CPU utilization and increased request latencies, eventually causing Border Gateway Protocol (BGP) flapping on the routing infrastructure and client disconnects. |
