You can submit a request for a quota increase directly from My quotas. Follow the steps below to request an increase for a quota. For this example, you can select any adjustable quota in your subscription.
Enter "quotas" into the search box, and then select Quotas.
On the Overview page, select a provider, such as Compute or AML.
Note
For all providers other than Compute, you'll see a Request increase column instead of the Adjustable column described below. There, you can request an increase for a specific quota, or create a support request for the increase.
On the My quotas page, under Quota name, select the quota you want to increase. Make sure that the Adjustable column shows Yes for this quota.
Near the top of the page, select New Quota Request, then select Enter a new limit.
In the New Quota Request pane, enter a numerical value for your new quota limit, then select Submit.
Your request will be reviewed, and you'll be notified if the request can be fulfilled. This usually happens within a few minutes.
If your request isn't fulfilled, you'll see a link to create a support request. When you use this link, a support engineer will assist you with your increase request.
