Latest Message<\/th>\nTitle: Some users may be unable to access or receive prompt responses with Microsoft 365 Copilot Chat or Copilot Notebooks <\/p>\n

User impact: Users may be unable to access or receive prompt responses with Copilot Chat or Copilot Notebooks. <\/p>\n

More info: Users may experience failing requests for the following scenarios:
– Image generation requests in Copilot Chat
– Prompt generation requests in Copilot Chat
– Failures when attempting to access or view Copilot Notebooks <\/p>\n

Current status: We’ve developed a fix that we expect will resolve the issue and are validating its efficacy before proceeding with deployment. We’ll provide a timeline for the deployment as one becomes available. <\/p>\n

Scope of impact: This incident impacts some users attempting to generate images or prompts using Copilot Chat or accessing Copilot notebooks. This section may be updated as the investigation progresses. <\/p>\n

Root cause: A licensing mismatch in the request flow is causing Copilot to view affected users as unlicensed, preventing them from completing requests or accessing Notebooks. <\/p>\n
