Hi,
You can do this via the admin center, and the easiest way to do this is to use the Upgrade tab in the admin center. If this is not available you can call up Microsoft Support over here get-help-support
ave time by starting your service request online. We'll help you find a solution or connect you to technical support.
Go to the admin center at https://admin.microsoft.com. If you get a message that says you don't have permission to access this page or perform this action, you aren't an admin. For more information, see Who has admin permissions in my business?.
On the bottom right side of the page, select Help & support.
Type a question or keyword into the text box. If you get a drop-down list, select the one closest to your question, or continue typing your question, then press Enter.
If the results don't help, at the bottom, select Contact Support.
Enter a description of your issue, confirm your contact number and email address, select your preferred contact method, and then select Contact me. The expected wait time is indicated in the Contact support pane.
Hope this helps.
