User impact: Users may be unable to view mailbox storage data in Outlook and Outlook on the web.

More info: Affected users are shown the following error message "Storage data is temporarily unavailable" when trying to view mailbox storage data for multiple mailboxes.

Current status: We've identified that a recent service build introduced an unsupported property into mailbox statistics data. When the service attempted to retrieve mailbox storage information, the unsupported property caused the request to fail and prevented mailbox storage data from being displayed. We've deployed a code fix to remove the unsupported property and are monitoring service telemetry to verify its success in fixing the issue.

Scope of impact: Some users attempting to view mailbox storage data in Outlook and Outlook on the web may be impacted. This information may be updated as our investigation continues.

Root cause: A recent service build introduced an unsupported property into mailbox statistics data returned by a backend process.

DetailsTitle: Users had access to scheduled prompts in 365 Copilot Chat when they shouldn't have

User impact: Users had access to scheduled prompts in Copilot Chat when they shouldn't have.

Current status: We identified that an update to a related service incorrectly allowed access to the paid service feature of scheduled prompts for users without an add-on Copilot license in Copilot Chat. A fix was applied to the service to correct this by changing the scope of users allowed to see the feature. This change removed the scheduled prompts feature from Microsoft 365 Copilot chat users.

- Microsoft reported and resolved an issue where users may have seen blank reports when downloading PBIX files from semantic models within Power BI. This issue is no longer actively occurring, and reports can be downloaded as expected from semantic models within Power BI. Affected users could download full reports for semantic models directly from .pbix files. https://status.dal.ca/service.php?Service=39 2026-06-17 15:14:16 Resolved:

This is being done due to concerns about the future of Cacti, as well as frustrations with Cacti and its (in)ability to gather complicated statistics such as Cisco-style traffic policies. The new implementation is a Grafana frontend with a Prometheus time series database backend. Grafana is far more modern and interactive, and the Prometheus database is non-lossy and has an easier and more predictable stats-gathering protocol.

The Grafana interface is up and running at https://graf.its.dal.ca/ , and uses the existing Dalhousie Active Directory for authentication just as Cacti does. Unfortunately, permissions to access graphs can't be assigned before the user first logs in.

When you have a spare moment, please attempt to log into the Grafana interface with your normal username and password. If the login fails, please let us know roughly when you tried and we'll investigate. If the login succeeds, please remember that there will likely be no visible graphs right away. We will be monitoring new logins on our side and will assign proper permissions as new users appear, so you should be able to see your traffic graphs by the day afterward.

At the moment we are trying to make the new graphs emulate the old Cacti graphs as much as possible, but if you have ideas on how you'd like the data to be presented, feel free to let us know and we'll attempt to make it happen if Grafana is capable of accommodating it.

Please contact brandon.hume@dal.ca if you run into any login problems, or for any customization requests. https://status.dal.ca/service.php?Service=6 2026-06-17 07:58:06 Users may be unable to see the free/busy status of multiple cross-tenant mailboxes in Exchange Online

User impact: Users may be unable to see the free/busy status of multiple cross-tenant mailboxes in Exchange Online.

More info: This impact occurs only when two or more mailbox statuses are requested.

Current status: We've validated that the source of impact was a NetCore deployment, which introduced a regression where headers were being dropped during free/busy status requests for cross-tenant scenarios, resulting in back-end authentication requests failing. Our fix to address the regression is currently at 90 percent saturation in the affected environment, and we've reached out to affected users to begin testing for remediation. https://status.dal.ca/service.php?Service=39 2026-06-17 07:56:17 Users may be unable to search and add addresses for emergency calling in auto suggest dialog in Microsoft Teams

User impact: Users may be unable to search and add addresses for emergency calling in auto suggest dialog in Microsoft Teams.

Current status: We're investigating a potential issue with Microsoft Teams and checking for impact to your organization. We'll provide an update within 30 minutes. https://status.dal.ca/service.php?Service=39 2026-06-16 11:11:11 Resolved Issue:

User impact: Users in North America may have experienced issues with Microsoft Teams.

Final status: While we were in the process of analysing service monitoring telemetry to isolate the source of the problem, system monitoring indicated that the service had returned to normal health. We've confirmed that the problem is no longer occurring, and we'll continue to monitor the service to ensure that the problem does not happen again. https://status.dal.ca/service.php?Service=6 2026-06-15 08:01:59 Active Issue:

User impact: Users may have been intermittently unable to copy an agent created through the Agent Builder into the full Copilot Studio.

Final status: We've completed deploying our aforementioned targeted fix and confirmed with our service telemetry that this issue is resolved. https://status.dal.ca/service.php?Service=38 2026-06-15 07:56:05 Users are unable to submit a prompt in Microsoft 365 Copilot Chat and receive an error message

User impact: Users are unable to submit a prompt in Microsoft 365 Copilot Chat and receive an error message.

More info: Microsoft 365 Copilot Chat returns the following error message "Something went wrong." for users when they submit a prompt.

Current status: While we continue to analyze the newly obtained HTTP Archive format (HAR) logs, we’ve identified a specific failure from service side telemetry and are looking into this further to determine the next steps required. https://status.dal.ca/service.php?Service=38 2026-06-15 07:46:41 Users may not see accurate usage data for Copilot Chat in usage reports within the admin center

User impact: Users may not see accurate usage data for Copilot Chat in usage reports within the admin center.

More info: This issue only affects usage data for unlicensed Copilot Chat users. Users may see lower than expected data reported for unlicensed Copilot Chat users.

Current status: We've determined that the under-reporting of usage data is being caused by a recent upgrade to the functionality of Copilot Chat for unlicensed users, which was not accounted for in current usage logging logic. We're investigating the recent upgrade to determine the next best steps for remediation. https://status.dal.ca/service.php?Service=8 2026-06-12 13:52:44 DetailsTitle: Some users may be unable to create new online meetings from shared calendar events in Exchange Online

User impact: Users may have been unable to create new online meetings from shared calendar events in Exchange Online.

More info: Affected users could create online meetings from their personal calendars as an alternative method, and existing shared calendar events remained unaffected.

Final status: We've confirmed that the fix to address the impact to the authorization component of the calendar service has completed and, after monitoring service health metrics to ensure the associated failures have ceased, we've verified the impact is remediated.

Scope of impact: Impact was specific to some users attempting to create new online meetings from shared calendar events in Exchange Online. https://status.dal.ca/service.php?Service=8 2026-06-12 09:43:21 CAUTION: The Sender of this email is not from within Dalhousie.

More info: Affected users may have been returned an error message stating, "Oops! Something happened. Can you try again?"

Users reported low-quality or inaccurate responses when Copilot Chat was prompted to respond on content within uploaded files.

Additionally, users who attempted to send a message with file grounding may have received the following response, "I tried to open your file {file name}, but I’m currently unable to retrieve its contents due to an access/activity limit on the file."

Final status: We've completed the scale-out of our configuration change to prevent retries from adding more load during OneDrive or SharePoint Online file uploads. After a period of monitoring for file upload traffic across affected regions, we've confirmed that our actions successfully remediated impact.
