Separation of accounts in the folder list

There needs to be a much clearer visual cue between accounts in the folder list- currently it is very easy to scroll past the end of one account’s folders and in to the next account’s folders with out realizing you have done so. I’m sorry to say, but the delineation that Outlook 2016 provides is better.

I don’t see much difference between the two clients in this regard.

But I do agree that some personalization in the folder tree would enable the accounts to appear more separate.
