Zimbra Email and Collaboration

Benefits of Collaboration beyond Email

Every organization has access to basic email or a standard email server, but fewer have shared calendars- and fewer still mobility or document management. That’s a serious loss of potential productivity- and often legacy platforms contribute to this imbalance by presenting complexity and financial obstacles relegating most organizations to limited functionality.

Next-generation email and collaboration platforms offer solutions to these and many other common pain points by providing innovative features for end-users and IT administrators at lower total cost-of-ownership (TCO).
