    Hello,

    This issue is not related to Windows for Business or Windows 365 Enterprise. It is specifically tied to quota management in Azure/OpenAI service subscriptions.

    When you attempt to deploy models such as claude sonnet4.5 or opus4.5 and receive the message that “no quota is available in any zone,” it means your subscription does not currently have capacity assigned for those models. Azure OpenAI enforces quota limits per model family and per region. If your subscription has not been granted quota for those specific models, you will not be able to add them, regardless of the region you select.

    The resolution path is to verify your quota allocation in the Azure Portal under Azure OpenAI Resource > Quotas. If the models you are trying to use are not listed with available quota, you need to submit a quota increase request through the Azure Portal. Microsoft reviews these requests and grants quota based on subscription eligibility and capacity availability. If you already submitted a request and it was denied, then you will not be able to deploy those models until Microsoft expands availability.

    In short, the error is not a technical misconfiguration on your side but a quota allocation issue. You will need to request quota for the specific models and wait for approval. If approval is not granted, the models cannot be deployed in your subscription.

    I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

    If you are encountering a "no quota" message when trying to use the Claude Sonnet 4.5 or Claude Opus 4.5 models, it may be due to the quota limits set for these models in your Azure subscription. Currently, only Enterprise and MCA-E subscriptions are eligible for Claude model usage in Foundry, and there are specific rate limits for these models. If you are on a different type of subscription, you may not have access to these models.

    To resolve this issue, you can consider the following steps:

    1. Check your subscription type: Ensure that you have an Enterprise or MCA-E subscription.
    2. Request a quota increase: If you are eligible, you can submit a request through the quota increase request form to increase your limits.
    3. Monitor usage: Keep track of your token consumption and request patterns to ensure you are within the allowed limits.

    If you continue to have issues, you may want to refer to the common subscription-related errors documentation for more guidance.
