More info: Impact may also occur within Microsoft Teams on the web, and any file viewing requests reliant on the API leveraged for viewing files through Microsoft Teams may fail.
Current status: We've successfully reproduced the impact and confirmed that the issue is only reproducible in the Microsoft Teams desktop client; the web client is unaffected. We're reviewing logs captured from our reproduction and identified that requests to gather information are being misrouted as the sites themselves are created in English, rather than in the language of their organization's locale as intended. This results in requests to retrieve the document library failing due to the mismatch in languages. We're continuing to investigate our reproduction logs to determine why this is occurring and formulate potential remediation actions.

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

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.

Service:Microsoft 365 suite
Feature Group:Portal
Classification:incident
Last Updated:Tue May 13 19:42:55 2025
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.

Last Updated:Tue Apr 22 18:21:14 2025
Root Cause:We were deploying a configuration change, intended to improve the File Preview feature within Microsoft Teams, through our Safe Deployment Processes. The rollout had gone through a staged rollout through our internal rings and had reached a section of public preview/TAP environment, where it had been paused from advancing further whilst we monitored for an extended period and performed further validations. The configuration change was working as expected without any issues and had been active within the public preview/TAP environment for an extended period of time.

Description:Title: Users may have been unable to share new files or view previously shared files within Microsoft Teams
User impact: Users may have been unable to share new files or view previously shared files within Microsoft Teams.
More info: - Users attempting to share new files may have received the errors 'Oops, something happened with the editor. Reload'. - Users attempting to view previous Teams Chat/Channel messages that contained a shared file may have received the error 'Error encountered while rendering this message' for that specific message.
As a workaround during the issue, users were able to view/access previously uploaded files when accessing from the 'Shared' tab within all Teams clients. Additionally, users were able to upload new files directly into Chats/Channels, or view previously uploaded Files directly from Chats/Channels when using the Teams iOS app.
Final status: After reverting the configuration change, we’ve received multiple reports from previously impacted users that the issue is no longer occurring. Additionally, monitoring telemetry shows error rates have fallen to expected levels.
Scope of impact: Impact was specific to users who were currently configured on public preview or part of the Technology Adoption Program (TAP).

Root cause: We were deploying a configuration change, intended to improve the File Preview feature within Microsoft Teams, through our Safe Deployment Processes. The rollout had gone through a staged rollout through our internal rings and had reached a section of public preview/TAP environment, where it had been paused from advancing further whilst we monitored for an extended period and performed further validations. The configuration change was working as expected without any issues and had been active within the public preview/TAP environment for an extended period of time.
On Tuesday, April 15, we started the process to resume the deployment to the remaining sections of the public preview/TAP environment. During the process of reactivating the rollout, there was a manual error that inadvertently changed a specific rollout parameter format. The deployment system generated an error due to this identified parameter format change, and the assumption was made that deployment reactivation process did not continue. However, due to an unexpected behavior of the deployment system, the rollout did in fact go through with configuration change that included incorrect parameter format.
As the specific File parameter was now in a different format (a string, rather than an array), a validation check, made by the Teams client for any request related to File content sharing, failed because the Teams client expected the previous parameter format and was unable to process the result, causing impact.
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' devices may have been offered a Windows 11 upgrade despite Microsoft Intune policies being configured otherwise.
More info: While we worked to address the issue, admins in impacted organizations may have been able to circumvent impact by pausing Windows Feature Updates until the code fix was deployed.
The following article has the steps that impacted users could've followed: https://learn.microsoft.com/en-us/intune/intune-service/protect/windows-10-update-rings#pause
We've previously deployed a fix to ensure further devices don't encounter impact. Devices which hadn't yet reached the In Progress, Update state with the Install started substate were not impacted. These states could've been checked in "Organization report" if devices were enabled to share diagnostic telemetry.
Final status: We’ve confirmed from service telemetry that this issue is no longer occurring. We advise that previously affected admins remove the pause the on Windows Feature Updates gradually, rather than all at once, to experience full impact remediation, and contact a support representative should any issues persist.
Scope of impact: Some users that leverage Windows desktop devices may have been impacted.
