How to share a folder with external users?

Ok so something like this?.....

• Team Folder (give acces to Group containing team members)
  • Sub-folder 1 (also give access to exteranl users 1 & 2)
    • Sub-folder 1.1
    • Sub-folder 1.2
    • Sub-folder 1.3 (also give access to external users 3 & 4)
    • Sub-folder 1.4
    • Sub-folder 1.5

Hmmmm ok, so like this?.....

• Team Folder (give acces to Group containing team members, manually give external users 1 &2)
  • Sub-folder 1 
  • Sub-folder 2
  • Sub-folder 3 (also give access to external users 3 & 4)
  • Sub-folder 4
  • Sub-folder 5

I want to clarify because I tried that but it seems I can only add Groups to a team folder... not external users manually.

Ok, i'm i bit confused... what did you mean by "That would work perfectly yes! You can even add the external users to the top level folder also if needed, you will just need to add them manually instead of with the group, as you can only add team members to a group."

Can you please clarify what you meant there?  It sounds like you were saying to add the external users to the Team Folder manually, instead of with the group... which is not  possible.  Was that your mistake? Or my misunderstanding?

Thanks for clearing that up!   The logical next question is: how do i use this 'new' Team Folder?  Doing it the sub-folder within a sub-folder way in order to have the ability to share with externals seems like a workaround.   The 'new' Team Folder might be less confusing for the end users.   

Thanks for that clarification, didn't realize it was an early access feature.   Unfortunately I only see 'New Desktop Dropbox App', no others... i'm guessing this means our business doesn't have the option to use this feature until it moves out of early access?

"I’d also like to note that the way the external user would see the folder wouldn’t change at all, since they will see the folder you share with them (regardless of its location within your team folder) as the “top level” folder in their account like how a shared folder appears.".  Yes.. I can think of situations where you'd not want the external user to know the internal folder structure. 

Howerver, although this sounds like a benefit, being able to see the parent folder is can be useful because it gives context to the folder they in fact are allowed to access.  It sounds like this means we have to name that folder as if it was standalone so the external folks know what they are looking at.  (Imagine naming it 'Photos' or something generic... if the external user had folders shared with them from other people named in a similarly generic fashion they'd have a hard time knowing which is which). 

Actually, maybe you have a solution for that.  How does one differentiate between two or more folders that had been shared with them that are the same... ie. if i have a bunch of people sharing a folder named 'Photos' with me, how do I tell which is which without the benefit of seeing (but not accessing data in) their parent folders?
