The ability to use this program in conjunction with our other programs. There is nothing I don't like about it, but if you do have any issues please contact them immediately! They provide very quick responses. This software makes keeping track of emails much easier than manually storing documents or emailing them back and forth between our attorneys for each document request we receive. It's also great how easy they make requests from clients when necessary as well. I like how easy it is to navigate through all of their options-they have many different tools for managing data, so you can do things quickly or take your time if needed! There's nothing i dislike about this program yet but there really isn't anything specific either (yet). It does what we need which makes us happy because they're constantly improving our experience with them as well. We use transperfect group e discovery mainly for legal hold management/file retention purposes.
