If you're a Dropbox Business team admin, follow these steps to cancel your Dropbox Business trial:

1. Sign in to the Dropbox website.
2. In your business account, enter your Admin Console from the left sidebar.
3. Go to your team's Account page.
4. Click the Cancel Dropbox Business link in the bottom-right of the page.

If during your trial you connected a personal and a work Dropbox, your Dropbox Business account will become a second personal Dropbox. Your original personal Dropbox will remain the same.
