Microsoft Exchange Server, more widely known as Microsoft Outlook or Outlook Web access, is an email management system that centralises a user's messages, contacts and calendar through Microsoft Exchange software and stores it on a server.
Lifewire summarises its communication and organisational features as:
- Email hosting
- A calendar component, including collaborative features like meeting invites, shared calendars and bookable resources
- Contact management providing an organisation-wide address book, as well as personal contact stores
- Collaborative task management, such as the ability to delegate tasks to another user
- Sticky notes, files and others
For years, it's been the backbone of business. Thousands of SMBs and corporate customers have used it as their primary mail server. But soon, the groupware server is undergoing changes that may impact them in a big way.
