To request a callback, you typically need to follow the support process for the specific Microsoft product you are using. If you are using Microsoft Intune, you can provide a description of your problem and select your preferred method of contact in the admin center. Make sure to include your contact information and any relevant details to expedite the process. For urgent matters, you might want to specify the severity of your issue if you have a Premier or Unified support contract, as this will help prioritize your request.
If you're trying to get a callback from a call queue in Microsoft Teams, ensure that you wait for at least 60 seconds in the queue, as that is the eligibility time for a callback. Once eligible, you can request a callback, but keep in mind that the call queue timeout must be configured appropriately to allow for this.
For more detailed guidance, please refer to the relevant support documentation for the specific Microsoft service you are using.
