Shared folders should take up space only from the owner's account, not from the members'.

Hey Hannah !  Thanks for this information.  The Remove My Access steps worked for me and that was very helpful. 

I can understand why it's more profitable for Dropbox to charge quota against everybody who contributes to the folder of the user who's paying for that storage even if I don't agree with it, so I get that Dropbox isn't going to change that practice any time soon.  But I feel like it might be helpful for people to understand what's going on a little more clearly--there's a potential that one user sees a folder they don't own counting against their storage, deletes it because they think it just gets deleted out of their storage, and they've just deleted someone else's files.

I suspect I'm not the only person to run into this situation.

I would also suggest that there be some way for a Basic user to actually contact Dropbox in the event of an issue--as we see here, I had to use the Feature Request to get someone's attention.  The chatbot just said it couldn't help me, directed me to the support page, and the support page told me I couldn't get support without paying Dropbox.  My next step would have been to look up your business registry information and start calling phone numbers, which honestly sucks for everybody.

I have multiple storage accounts, so paying to have my business e-mail address using storage I don't need just because a client also uses Dropbox isn't economical to me.  

yidanz - thanks for the Dropbox File Request suggestion! That would be useful and if I can ask my clients to use that, and it doesn't impact my own storage quota, that would help.  I've bookmarked the link and I'll keep it handy for in future.

Thank you both for the help.  I hope this experience is also helpful to Dropbox for future reference too.
