DetailsTitle: Admins' Microsoft 365 Copilot usage reports within the Microsoft 365 admin center may be delayed

User impact: Admins' Microsoft 365 Copilot usage reports within the Microsoft 365 admin center may be delayed.

More info: The affected Copilot usage reports consist of the following:

-Microsoft 365 Copilot usage reports

-Microsoft 365 Copilot Chat usage reports

-Microsoft Graph API Copilot usage reports

These reports will be delayed beginning Wednesday, June 10, 2026, at 12:00 AM UTC.

Current status: Our service telemetry alerted us to an issue in which admins in North America and Asia Pacific regions may receive Copilot usage reports delayed through the Microsoft admin center. We've identified that a delay in our upstream process for Copilot source data is preventing Copilot usage reports from publishing up-to-date data and is resulting in delayed reporting. We're examining this affected upstream process to pinpoint the underlying cause for the delay and to develop a remediation strategy.

Scope of impact: Any admin located in North America and Asia Pacific regions attempting to view up to date affected Copilot usage reports through the Microsoft 365 admin center listed in the more info section may be impacted by this event. This section may be updated as our investigation continues.

Root cause: A delay in our upstream process for Copilot source data is preventing Copilot usage reports from publishing up-to-date data and is resulting in delayed reporting.

ID: MO1332784Issue type: Advisory

Status: Service Restored

Impacted services M365 suite

User impact: Users' Windows devices with configured policies to prevent auto updates might have been installing drivers.

More info: As we worked to remediate the impact, we determined that the drivers installed were Microsoft approved/signed and that they didn't pose a security threat.

Final status: We've validated that this issue is resolved following impact remediation confirmation from a subset of previously affected users.

Scope of impact: This issue may have caused drivers to be installed for users with a Windows device configured to prevent auto updates.

Start time: Tuesday, June 02, 2026, at 1:00 PM UTC

End time: Wednesday, June 03, 2026, at 5:30 AM UTC

Root cause: A caching service used by the Windows Update service temporarily dropped device enrollment information. As a result, affected Windows devices were briefly treated as non-enrolled, preventing the expected driver-approval controls being applied.

Next steps:

- We're continuing to review how this caching service temporarily dropped Windows device enrollment information to better inform how to detect, prevent, and respond to similar service issues in the future.

This is the final update for the event. https://status.dal.ca/service.php?Service=39 2026-06-04 09:14:31 Users' Microsoft Teams Webinar registration confirmation email messages are delayed up to three hours

User impact: Users' Microsoft Teams Webinar registration confirmation email messages are delayed up to three hours.

More info: Impact typically occurs for one to three hours between the time frame of 1:00 PM UTC to 11:00 PM UTC.

Current status: We've identified an increase in request traffic to the portion of service infrastructure responsible for facilitating Webinar registration confirmation email messages which is causing delays when delivering them to end users. We're evaluating mitigation options to determine the most efficient method to remediate the impact. https://status.dal.ca/service.php?Service=38 2026-06-03 09:39:26 Some users' Windows devices with policies configured to prevent auto updates may be installing drivers

User impact: Users' Windows devices with configured policies to prevent auto updates may be installing drivers.

More info: As we work to remediate the impact, we've determined that the drivers being installed are Microsoft approved/signed and that they don't pose a security threat.

Current status: We've identified a potential service cache misconfiguration that we believe could be causing drivers to become unexpectedly installed when policies are configured to prevent it. We're further analyzing our service cache configurations to confirm our findings, and so we can determine the next steps for remediating the impact. https://status.dal.ca/service.php?Service=38 2026-06-03 08:35:08 Microsoft Copilot:

User impact: Users may have been unable to start screen sharing in 1:1 calls using Microsoft Teams web client.

More info: This issue only affected users leveraging Chromium-based browsers, such as the Edge or Chrome browser, attempting to screenshare in a 1:1 call on the Teams web app. Additionally, the first screen sharing session in each call wasn't affected; only subsequent screen-sharing attempts may have been impacted.

While we were working to remediate this issue, affected users could still perform screen sharing by:

- Using the desktop or mobile apps

- Leveraging a non-Chromium-based browser

- Adding another user to the call

- Ending and restarting the call

Final status: Our fix is now fully deployed to both Mac and Windows devices, and any users still encountering the issue can update their Teams web client to the latest version to receive the fix and remediate impact. https://status.dal.ca/service.php?Service=12 2026-05-28 07:56:22 Beginning Monday, June 1st, crews will be mobilizing to start necessary structural repairs to the exterior concrete ramp located on the west side of the building.

Temporary fencing will be installed around the ramp area to clearly identify and secure the work zone for the duration of the project.
