I have a user who says that every time they log in they are taken to their address book. They'd prefer that their inbox is the default. Is there a fix or a setting for this? I can't reproduce.
My guess is they that they bookmarked RoundCube when they where in the address book (<RC url>/?_task=addressbook) so every time they click on the bookmark it will take them to the login page which will automatically forward them to the address book once they login.
