User impact: Users may be unable to view on-premises or cross-tenant free/busy availability when scheduling meetings.
More info: Cross-tenant or on-premises free/busy lookups via the Outlook Scheduling Assistant fail for attendees in a specific domain. As a result, availability consistently appears as “Unknown,” preventing effective meeting scheduling.
Current status: We've isolated that impact is not limited to users in the Asia Pacific region, and we've updated the "Scope of impact" field of our communications to reflect this. We're working with a subset of affected users to schedule a debugging session to collect additional logging during a reproduction of impact to assist with furthering our root cause analysis.
Scope of impact: Impact is specific to some users attempting to view free/busy availability. This information may be updated as our investigation continues. https://status.dal.ca/service.php?Service=39 2026-05-11 09:27:30 Users may see incorrect characters in incoming Microsoft Teams call notifications when display names contain diacritics

User impact: Users may have been unable to adjust their camera brightness in Microsoft Teams settings.
More info: When attempting to adjust camera brightness, users may have received a message stating "Adjust brightness is unavailable. Check your network connection, or contact your IT admin."
Affected users will need to upgrade to Teams build version 26093.415.4620.1935 for Windows clients and version 26093.311.4599.3126 for Mac clients in order to fully remediate impact.
Final status: We've confirmed that the builds have deployed to the remaining affected users and the impact is remediated.
Scope of impact: This issue may have affected any user attempting to adjust their camera brightness in Microsoft Teams settings.
Start time: Friday, February 27, 2026, at 4:37 AM UTC
End time: Thursday, May 07, 2026, at 6:38 PM UTC
Root cause: The ability to adjust camera brightness was no longer operable due to an unrelated issue where crashes in Teams meetings were occurring due to a code issue relating to the setting, which resulted in impact.
Next steps: We're reviewing our code testing and validation procedures to identify and prevent similar issues with crashes in Teams meetings that cause the ability to adjust camera brightness to no longer be operable, which will help us prevent similar impact from occurring in the future.
