| Description: | Title: Some users may incorrectly receive suggestions by Microsoft Copilot (Microsoft 365) to generate a file download link
User impact: Users may incorrectly receive suggestions by Copilot to generate a file download link.
More info: This issue occurs for declarative agents when code interpreter is disabled and users are returned a broken link. When Copilot generates a file, the link provided points users to "sandbox:/mnt/data/FILE_NAME" which isn't an accessible environment.
This behavior is encountered when using either a declarative agent or a notebook.
Users using a Copilot declarative agent can enable code interpreter to alleviate impact while we continue to investigate this incident.
Current status: We've determined that code interpreter must be enabled to generate a file download link and that Copilot is attempting to perform this function when it isn't enabled by default. Based on our improved understanding of this event, we’ve updated the Title, User impact, and Scope of impact fields of our communication. To remediate impact, we're identifying ways of to correct Copilots behavior so that it informs users that this function isn't available if code interpreter isn't enabled.
Scope of impact: Some users may incorrectly receive suggestions by Copilot to generate a file that result in a broken download link while code interpreter is disabled.

| Description: | Title: Users may be unable to access their mailbox using any connection methods
User impact: Users may have been unable to access their mailbox using any connection methods.
More info: Impacted connection methods included, but may not have been limited to:
- Representational State Transfer (REST) API
- Outlook on the web
- Exchange ActiveSync (EAS)
- Messaging API (MAPI)
Final status: The configuration change has fully saturated in all affected infrastructure. We've verified that the service is healthy by monitoring telemetry and confirming resolution with previously affected customers.
Scope of impact: Users attempting to access their Exchange Online mailbox using any connection methods may have been impacted.
Start time: Wednesday, July 9, 2025, at 10:20 PM UTC
End time: Thursday, July 10, 2025, at 4:41 PM UTC
Preliminary Root Cause: A recent service update to an authentication component unintentionally prevented access for a subset of users, resulting in intermittent service unavailability.
Specifically, two certificates within the service configuration were not expected to be in active use and subsequently decommissioned. Our standard procedure includes deleting these certificates in stages via our Safe Deployment Practices (SDP) however, a recent system regression inadvertently caused the deletion of these certificates to occur in all environments simultaneously, resulting in 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.

More info: Users may experience errors in policy distribution status, or events failing to trigger the necessary retention label actions such as deletion or re-labelling.
Current status: After investigating the unexpected issues we encountered during the validation phase of the previously mentioned fix, we’ve identified that a time zone mismatch within another part of our service infrastructure is causing failures when processing the right objects, thus resulting in the validation delays. We’ve developed a secondary code fix to address the time zone mismatch and are deploying it to our internal environment to validate it prior to deployment. In parallel, we’ve also completed the validation process for the first fix, which we’ll provide timelines for deployment for both fixes once validation of the second fix has completed.

User impact: Users may have experienced issues with various Microsoft 365 services
More info: We've confirmed that impact occurred, though was not limited, to the following services:
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
-Users' status information may have been stale
Microsoft Purview and Microsoft Defender for Office
- Users may have faced intermittent authentication failures when attempting to access solutions tabs and features in Microsoft Purview and Defender portal
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.

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.

| 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.
