Title: Some users with edit and full control permissions may be unable to access or share some files in Microsoft OneDrive
User impact: Users with edit and full control permissions may have been unable to access or share some files in OneDrive.
More info: Specifically, this issue impacted files, folders, and list items that were deleted and recently restored from the recycle bin. Impacted users attempting to access or share some folders experienced failures in sharing and permission operations in OneDrive.
Additionally, processes that attempted to enumerate permissions on these items may have seen failures.
Site administrators still had complete access to the content that was been deleted and restored.
Final status: We've monitored service health telemetry to confirm that our fix has remediated the impact.
Scope of impact: Some users with edit and full control permissions who were attempting to access or share some folders in OneDrive that were deleted and restored from the recycle bin may have been impacted.
Start time: Monday, October 13, 2025, at 3:50 PM UTC
End time: Friday, February 20, 2026, at 10:45 AM UTC
Root cause: A recent deployment contained a code regression that introduced a compatibility issue between code that was preventing items that had been deleted and recently restored from being accessible again.
Next steps:
- We're reviewing our update procedures to understand why impact to file access wasn't caught during the testing phase. This will allow us to drive service improvements by proactively identifying similar issues in the future and improve our update testing processes.
This is the final update for the event. https://status.dal.ca/service.php?Service=21 2026-02-20 15:12:02 Resolved:

User impact: Users' MailTips may not reflect free/busy correctly in Outlook desktop and crashes may occur when adding mailboxes.
More info: This issue is specific to the Outlook desktop client in organizations with a hybrid environment using Exchange Web Services (EWS) for MailTips. Users may notice that the MailTips free/busy feature isn’t operating as expected and may see an error stating “we can’t show MailTips right now.”
The Outlook desktop crashes occur when attempting to add a new on-premise mailbox.
Admins may be unable to create new on-premise mailboxes and their cross-tenant AutoDiscover requests general may fail from hybrid environments.
Current status: We’ve determined that a routing change for Autodiscover requests introduced a header duplication issue causing a backlog of requests that ultimately fail or timeout, resulting in the impact. We’ve confirmed that, in addition to AutoDiscover failures and Outlook crashes, users may experience the MailTips free/busy feature isn’t operating as expected and may see an error stating “we can’t show MailTips right now.” As we develop a fix to address this issue, affected admins may be able to mitigate the impact by recycling the Autodiscover application pool. We anticipate having an estimation for the delivery of the permanent fix to resolve this issue by our next scheduled update.
Scope of impact: Any admins’ cross-tenant AutoDiscover requests may fail from hybrid environments, causing MailTips free/busy not to show and crashing for users’ Outlook desktop clients when adding additional on-premises mailboxes. This information may be updated as our investigation continues.
Start time: Tuesday, January 27, 2026, at 12:30 AM UTC
Root cause: A routing change for Autodiscover requests introduced a header duplication issue causing a backlog of requests that ultimately fail or timeout, resulting in the impact.
Next update by: Monday, February 9, 2026, at 8:30 PM UTC https://status.dal.ca/service.php?Service=6 2026-02-09 10:20:06 Title: Some users' legitimate email messages may be marked as phish and quarantined in Exchange Online
User impact: Users' legitimate email messages may be marked as phish and quarantined in Exchange Online.
Current status: We're continuing to release the quarantine messages for the affected users to fully resolve this problem. In parallel, we're actively working to evaluate additional remediation actions to perform in order to expedite the process of recovery.
Scope of impact: Some users attempting to send or receive Exchange Online email messages may be impacted.
Root cause: The email messages are getting incorrectly marked as phish and quarantined in Exchange Online due to ever-evolving criteria aimed at identifying suspicious email messages, as spam and phishing techniques have become more sophisticated in avoiding detection.
Next update by: Saturday, February 7, 2026, at 12:30 AM UTC https://status.dal.ca/service.php?Service=39 2026-02-09 10:16:48 Title: Users may be unable to select or find meeting rooms when creating channel meetings in Microsoft Teams
User impact: Users may have been unable to select or find meeting rooms when creating channel meetings in Microsoft Teams.
Final status: We've monitored the deployment progress of the fix and we've now confirmed that it has fully deployed, resolving the impact.
Scope of impact: Any user attempting to select or find meetings rooms when creating channel meetings in Microsoft Teams may have been impacted.
Start time: Thursday, January 22, 2026, at 12:09 AM UTC
End time: Friday, February 6, 2026, at 5:00 AM UTC
Root cause: A code regression inadvertently introduced in a recent update was causing a graph API which Microsoft Teams relies on for scheduling channel meetings with a meeting room to fail.
Next steps:
- We're reviewing our update procedures to understand why the code regression wasn't identified during our testing phase. This will help us to improve our testing processes and proactively identifying similar issues in the future.
