Impacted servicesMicrosoft 365 Copilot Chat


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.

Scope of impact: Users without an add-on Copilot license had access to scheduled prompts in Copilot Chat when they shouldn't have. https://status.dal.ca/service.php?Service=8 2026-06-29 08:44:31 DetailsTitle: Users may be unable to sign into Microsoft Teams Rooms (MTR) on Windows devices
