When we think about email collaboration/unified messaging the first things comes into our mind is Microsoft exchange, probably not because they pioneered email collaboration but because they have great success of with all enterprise segments, more importantly the end users to felt the impact of email collaboration. Microsoft Exchange Server 4.0 was released at 1996 something that could be integrated to directory services; it was probably the first competitor to Lotus notes released in early 90s.
Let’s not forget novel. In 1990 brought the release of WordPerfect Office 3.0, adding Macintosh and UNIX to the client mix and supporting multiple servers with cross-server email, calendaring and scheduling. The next version 3.1 even included remote sync.
Today’s email Collaboration / Unified messaging
Today when try to understand email collaborative software, we think about something more than email and address book. It is also called unified messaging. Enables us to share calendar events and task lists, update presence information, advanced email routing, global/corporate address book, sharing documents and other media without having to attach it, email auto responders; most importantly, access to all these through push notification support from of your favorite desktop collaboration application, mobile, tablet, or just any web browser. Email collaboration systems are also expected to be integrated with the directory services as well as other collaboration system running within the enterprise.
Things we take for granted, antivirus, anti spam, central authentication, high availability, monitoring, backup etc.
