If you're a Dropbox Business team admin, and you don’t want your team members to access both a personal and work Dropbox account on their desktops, you can decide to allow only a single account on each computer.

Allow only a single Dropbox account on each computer

1. Sign in to dropbox.com with your admin account.
2. Click Admin Console in the sidebar on the left.
3. Click Settings.
4. Under Device security, click Multiple accounts.
5. Click No and team members will only be able to link their work Dropbox to their computer.

If a team member has already signed in to both a personal Dropbox account and work Dropbox account, and you subsequently allow only a single Dropbox account, whichever account was signed in to second will be unlinked from the member's desktop. The account that was signed in to first will remain linked to the desktop. Team members will still be able to access both accounts via the website and the Dropbox mobile app.
