Unable to access the sustainability manager free trail
Some organizations don't allow their team members to sign up for trials directly. Therefore, when you try to sign up for the Microsoft Sustainability Manager trial, you might receive the following message: "Your company doesn't allow team members to sign up with their work email." In this case, you must work with your IT team and have the organization's Microsoft 365 administrators complete the process of joining your organization to the trial.
In order to deploy the trial
A Microsoft 365 administrator of your organization must follow these steps to deploy the Microsoft Sustainability Manager trial.

In the left navigation, select Billing and then Purchase services.
Search for the keyword Sustainability.

Select Start free trial to initiate an order and checkout process.
Select Try now to complete the checkout process. This step effectively purchases a license for the Microsoft Sustainability Manager trial and applies it to your organization free of charge ($0.00).
Review the order confirmation, and then select Continue to return to your home page in the Microsoft 365 admin center.
You have now obtained a Microsoft Sustainability Manager trial license for your organization.
