The best part of message logic was that it allowed us all access from different locations with out having our own server or anything like this! It also allows for multiple users in one account which can be helpful if you are working remotely as well but I would recommend getting your first version because there were some bugs when we started using them at my work place (it took about 3 weeks before they fixed everything). We used their service mainly so people could send emails without sending through another domain/server since most companies don't allow non-domain mail servers anymore unless its specifically stated by someone higher up than me(which isn' t often!).
