I was sharing a file with a client and I accidentally joined their team. How do I leave it?

Hey mbarbuto! Thanks for posting this on our Community today. 

Now, since I understand you’ve joined your client’s Dropbox team indeed, the admin of that team will need to remove you from it and convert your Dropbox account back to a personal one. 

Please make sure they follow these steps, so as to not delete your account instead during the process.

After that, your account should go back to a free Basic one, along with your existing files, and you can re-upgrade it to Plus, if you wish to. 

If you have further questions though, I’ll be here.
