If you ever have any questions or issues with your Office 365 system, Microsoft has a responsive and knowledgeable support team. To get support for your Office 365 or Dynamics CRM Online, navigate to the Admin Center page in the Microsoft Online Portal, and click on Service Requests. From here, you can create a new request and specify the details of your issue. A Microsoft engineer will contact you shortly (typically the same day, and oftentimes within minutes) to help you with your issue.
For creating a service request ticket with the Office 365 team via phone, simply dial 1-800-865-9408. Note: This number is only for United States Office 365 clients.
