Microsoft Outlook/Exchange is popular due to its user-friendliness and its advanced features, which give a big boost to productivity:

• Up-to-date: Exchange stores everything centrally, so you always see the latest version of your email, files, calendar and contacts.
  
  
• Mobile access: Exchange is the software that powers email for handhelds like the BlackBerry or Treo. It also offers sophisticated Web mail, so you will always be in-sync with your team.
  
  
• Shared calendars: Lets employees see colleagues' availability to schedule or rearrange meetings, book conference rooms, and plan projects.
  
  
• Shared task lists: Allows ‘to do’ lists to be created and assigned, then shared with team members. Managers can check off items as they are completed.
  
  
• Shared contacts: Company or shared address books means your customers‘ contact details will never be lost or misplaced.
  
  

Microsoft Outlook/Exchange lets employees share information and work together extremely productively, in a way that is otherwise impossible.
