Unsubscribe, Remove, or Reset Dynamics 365 for Finance and Operations, Business edition
When you have signed up for Dynamics 365, you can choose to cancel your subscription at any time. Similarly, you can choose to reset the company that you can been using in Dynamics 365. For a quick overview, see the Dynamics 365 blog.
Unsubscribing by removing Dynamics 365 from your Office 365 experience
If you have subscribed for Dynamics 365 using an existing Office 365 business account, you must ask your Office 365 administrator to remove the Dynamics 365 license from your user account.
User accounts and licenses are managed in the Office Portal. Only administrators can remove Dynamics 365 licenses from user accounts. The Office 365 administrator can remove Dynamics 365 from your user account or remove the subscription from your company's account. If Dynamics 365 is removed from your user account, and other people from your company continue the subscription, they will still have access to your shared data in the Dynamics 365 company.
Unsubscribing from Dynamics 365 without Office 365
If you signed up for Dynamics 365 using a non-Office 365 business account, you do not have an Office 365 administrator. Instead, you must unsubscribe by contacting the Dynamics 365 Cancelation team. Currently, you must contact the team by sending an email message at firstname.lastname@example.org. You must include the name of your Dynamics 365 tenant in the message so that we can identify you. The easiest way to do that is to copy the URL from your Dynamics 365 Home page.
Resetting your Dynamics 365 experience
If you have added data to your Dynamics 365 preview and you want to start over with a fresh experience, you can create a new company and then reset the first company. If you open the Companies page, you can create a copy of your current company, sign out and then sign into your new company, and then reset the original company.
When you reset a company that you are sharing with other people from your organization, you must make sure other people are not logged in when you reset the company.
Removing Dynamics 365 from your app launcher
If you want to hide Dynamics 365 from your app launcher, you can quite simply unpin it. This does not remove any data, and it does not cancel your subscription.
