A few months ago, I was asked to set up a dropbox folder for a work project. I set it up and invited my collaborators to the folder. Fast forward a few months, and one of these collaborators is claiming that I messed up because they had no idea the folder existed - definitely not true, as this particular member was the one who asked me to set it up - and that they were never invited to it.
Now, I did manually send them a link to the folder via email, so they could have requested access any time, but it is true that when I go to the list of members, their name isn't on there. So maybe I did forget to invite them via Dropbox's share function. But is there a way for me to find out whether I actually forgot to invite them, or if they were invited, but removed themselves from the member list to make it seem like it was my mistake? It doesn't matter all that much, I'm just curious if it is possible. And if I did make a mistake I would like to know about it.
Tldr: would their email still show up in the list of members, even if they removed themselves, or would it disappear? And if a user's name and email disappears from the members list when they remove themselves, is there a way to go back and see past members or invites anywhere?
