I logged into my email account using Horde. I selected the option for address book, I get an option for a drop down menu with other people's names there as well as mine. I click to send a new message, click on address book, and the other people's books with their list of addressees is there, as well as my own. Why am I seeing their address book as well as my own? That could also mean the other people can see my address book as well, which is not appropriate. What's the fix for both of those situations, their books showing up and who has access to what?
